7957-402: The early 2000s, BioFETs such as the DNA field-effect transistor (DNAFET), gene-modified FET (GenFET) and cell-potential BioFET (CPFET) had been developed. A factor influencing the biotechnology sector's success is improved intellectual property rights legislation—and enforcement—worldwide, as well as strengthened demand for medical and pharmaceutical products. Rising demand for biofuels

8066-400: The engine itself, although this depends on the fuel rail design. Since biodiesel is an effective solvent and cleans residues deposited by mineral diesel, engine filters may need to be replaced more often, as the biofuel dissolves old deposits in the fuel tank and pipes. It also effectively cleans the engine combustion chamber of carbon deposits, helping to maintain efficiency. Biodiesel

8175-490: The engine or car), is less corrosive and less water-soluble than ethanol, and could be distributed via existing infrastructures. Escherichia coli strains have also been successfully engineered to produce butanol by modifying their amino acid metabolism . One drawback to butanol production in E. coli remains the high cost of nutrient rich media , however, recent work has demonstrated E. coli can produce butanol with minimal nutritional supplementation. Biobutanol

8284-608: The environment if spilled. However, production requires large amounts of energy and fertilizer, the produced fuel degrades faster than other biofuels, and it does not flow well in cold temperatures. By 2017, due to economic considerations, most efforts to produce fuel from algae have been abandoned or changed to other applications. Third and fourth-generation biofuels also include biofuels that are produced by bioengineered organisms i.e. algae and cyanobacteria. Algae and cyanobacteria will use water, carbon dioxide, and solar energy to produce biofuels. This method of biofuel production

8393-445: The evidence for the harm and lack of substantial equivalency of studied GMOs. We emphasize that with over 1783 published articles on GMOs over the last 10 years it is expected that some of them should have reported undesired differences between GMOs and conventional crops even if no such differences exist in reality. and Biofuel Biofuel is a fuel that is produced over a short time span from biomass , rather than by

8502-607: The fact these organisms are subject to intellectual property law. Biotechnology has several applications in the realm of food security. Crops like Golden rice are engineered to have higher nutritional content, and there is potential for food products with longer shelf lives. Though not a form of agricultural biotechnology, vaccines can help prevent diseases found in animal agriculture. Additionally, agricultural biotechnology can expedite breeding processes in order to yield faster results and provide greater quantities of food. Transgenic biofortification in cereals has been considered as

8611-407: The feedstock used. Electronically controlled ' common rail ' and ' Unit Injector ' type systems from the late 1990s onwards can only use biodiesel blended with conventional diesel fuel. These engines have finely metered and atomized multiple-stage injection systems that are very sensitive to the viscosity of the fuel. Many current-generation diesel engines are designed to run on B100 without altering

8720-698: The fermentation of sugars or starches (easiest to produce) or cellulose (more difficult to produce).The IEA estimates that ethanol production used 20% of sugar supplies and 13% of corn supplies in 2021. Ethanol fuel is the most common biofuel worldwide, particularly in Brazil . Alcohol fuels are produced by fermentation of sugars derived from wheat , corn , sugar beets , sugar cane , molasses and any sugar or starch from which alcoholic beverages such as whiskey , can be made (such as potato and fruit waste, etc.). Production methods used are enzyme digestion (to release sugars from stored starches), fermentation of

8829-468: The first biosensor in 1962. Biosensor MOSFETs were later developed, and they have since been widely used to measure physical , chemical , biological and environmental parameters. The first BioFET was the ion-sensitive field-effect transistor (ISFET), invented by Piet Bergveld in 1970. It is a special type of MOSFET, where the metal gate is replaced by an ion -sensitive membrane , electrolyte solution and reference electrode . The ISFET

8938-416: The first forms of biotechnology. These processes also were included in early fermentation of beer . These processes were introduced in early Mesopotamia , Egypt , China and India , and still use the same basic biological methods. In brewing , malted grains (containing enzymes ) convert starch from grains into sugar and then adding specific yeasts to produce beer. In this process, carbohydrates in

9047-428: The fuels either grow on arable land but are byproducts of the main crop, or they are grown on marginal land. Second-generation feedstocks also include straw, bagasse, perennial grasses, jatropha, waste vegetable oil, municipal solid waste and so forth. Biologically produced alcohols , most commonly ethanol, and less commonly propanol and butanol , are produced by the action of microorganisms and enzymes through

9156-429: The global production of bioethanol and biodiesel is 2.2 and 1.8 EJ per year, respectively. Bioethanol is an alcohol made by fermentation , mostly from carbohydrates produced in sugar or starch crops such as maize , sugarcane , or sweet sorghum . Cellulosic biomass , derived from non-food sources, such as trees and grasses, is also being developed as a feedstock for ethanol production. Ethanol can be used as

9265-416: The grains broke down into alcohols, such as ethanol. Later, other cultures produced the process of lactic acid fermentation , which produced other preserved foods, such as soy sauce . Fermentation was also used in this time period to produce leavened bread . Although the process of fermentation was not fully understood until Louis Pasteur 's work in 1857, it is still the first use of biotechnology to convert

9374-478: The highest yields) to produce enough food to support a growing population. As crops and fields became increasingly large and difficult to maintain, it was discovered that specific organisms and their by-products could effectively fertilize , restore nitrogen , and control pests . Throughout the history of agriculture, farmers have inadvertently altered the genetics of their crops through introducing them to new environments and breeding them with other plants — one of

9483-511: The lab for research and medical purposes, and fermentation , which is used to produce a wide range of products such as beer, wine, and cheese. The applications of biotechnology are diverse and have led to the development of essential products like life-saving drugs, biofuels , genetically modified crops, and innovative materials. It has also been used to address environmental challenges, such as developing biodegradable plastics and using microorganisms to clean up contaminated sites. Biotechnology

9592-718: The market, but in 2015 the FDA approved the first GM salmon for commercial production and consumption. There is a scientific consensus that currently available food derived from GM crops poses no greater risk to human health than conventional food, but that each GM food needs to be tested on a case-by-case basis before introduction. Nonetheless, members of the public are much less likely than scientists to perceive GM foods as safe. The legal and regulatory status of GM foods varies by country, with some nations banning or restricting them, and others permitting them with widely differing degrees of regulation. GM crops also provide

9701-432: The material that is fossilised or embedded in geological formations". This means that coal or other fossil fuels is not a form of biomass in this context. First-generation biofuels (also denoted as "conventional biofuels") are made from food crops grown on arable land. The crop's sugar, starch, or oil content is converted into biodiesel or ethanol , using transesterification , or yeast fermentation. To avoid

9810-815: The methods of genetic engineering . These techniques have allowed for the introduction of new crop traits as well as a far greater control over a food's genetic structure than previously afforded by methods such as selective breeding and mutation breeding . Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its Flavr Savr delayed ripening tomato. To date most genetic modification of foods have primarily focused on cash crops in high demand by farmers such as soybean , corn , canola , and cotton seed oil . These have been engineered for resistance to pathogens and herbicides and better nutrient profiles. GM livestock have also been experimentally developed; in November 2013 none were available on

9919-417: The most commonly used ethers in fuel to replace lead. Ethers were introduced in Europe in the 1970s to replace the highly toxic compound. Although Europeans still use bioether additives, the U.S. Energy Policy Act of 2005 lifted a requirement for reformulated gasoline to include an oxygenate, leading to less MTBE being added to fuel. Although bioethers are likely to replace ethers produced from petroleum in

10028-542: The new technology in 1972 by transferring genetic material into a bacterium, such that the imported material would be reproduced. The commercial viability of a biotechnology industry was significantly expanded on June 16, 1980, when the United States Supreme Court ruled that a genetically modified microorganism could be patented in the case of Diamond v. Chakrabarty . Indian-born Ananda Chakrabarty , working for General Electric , had modified

10137-404: The original on October 9, 2022. In spite of this, the number of studies specifically focused on safety assessment of GM plants is still limited. However, it is important to remark that for the first time, a certain equilibrium in the number of research groups suggesting, on the basis of their studies, that a number of varieties of GM products (mainly maize and soybeans) are as safe and nutritious as

10246-425: The potential land-use change required to produce additional biofuel feedstocks. The outcomes of lifecycle assessments (LCAs) for biofuels are highly situational and dependent on many factors including the type of feedstock, production routes, data variations, and methodological choices. This could be added to emphasize the complexity and variability in assessing the environmental impacts of biofuels. Estimates about

10355-437: The process of anaerobic digestion of organic material by micro-organisms . Other trace components of this mixture includes water vapor, hydrogen sulfide , siloxanes, hydrocarbons, ammonia, oxygen, carbon monoxide, and nitrogen. It can be produced either from biodegradable waste materials or by the use of energy crops fed into anaerobic digesters to supplement gas yields. The solid byproduct, digestate , can be used as

10464-463: The production of a chemical known as 1,4-butanediol , which is used in fiber manufacturing. In order to produce 1,4-butanediol, the authors alter the metabolic regulation of the Escherichia coli by CRISPR to induce point mutation in the glt A gene, knockout of the sad gene, and knock-in six genes ( cat 1, suc D, 4hbd , cat 2, bld , and bdh ). Whereas CRISPRi system used to knockdown

10573-460: The production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics. For example, this technique was used with corn to produce the largest and sweetest crops. In the early twentieth century scientists gained a greater understanding of microbiology and explored ways of manufacturing specific products. In 1917, Chaim Weizmann first used

10682-441: The products). The utilization of biological processes, organisms or systems to produce products that are anticipated to improve human lives is termed biotechnology. By contrast, bioengineering is generally thought of as a related field that more heavily emphasizes higher systems approaches (not necessarily the altering or using of biological materials directly ) for interfacing with and utilizing living things. Bioengineering

10791-422: The purpose of sustainable operations (for the return from bottomless initial investment on R & D) and gaining durable patents rights (for exclusives rights for sales, and prior to this to receive national and international approval from the results on animal experiment and human experiment, especially on the pharmaceutical branch of biotechnology to prevent any undetected side-effects or safety concerns by using

10900-761: The reaction of reactive iso-olefins, such as iso-butylene, with bioethanol." Bioethers are created from wheat or sugar beets, and also be produced from the waste glycerol that results from the production of biodiesel. They also enhance engine performance, while significantly reducing engine wear and toxic exhaust emissions . By greatly reducing the amount of ground-level ozone emissions, they contribute to improved air quality. In transportation fuel there are six ether additives: dimethyl ether (DME), diethyl ether (DEE), methyl tert -butyl ether (MTBE), ethyl tert -butyl ether (ETBE), tert -amyl methyl ether (TAME), and tert -amyl ethyl ether (TAEE). The European Fuel Oxygenates Association identifies MTBE and ETBE as

11009-422: The regulation of GMOs between countries, with some of the most marked differences occurring between the US and Europe. Regulation varies in a given country depending on the intended use of the products of the genetic engineering. For example, a crop not intended for food use is generally not reviewed by authorities responsible for food safety. The European Union differentiates between approval for cultivation within

11118-404: The respective conventional non-GM plant, and those raising still serious concerns, was observed. Moreover, it is worth mentioning that most of the studies demonstrating that GM foods are as nutritional and safe as those obtained by conventional breeding, have been performed by biotechnology companies or associates, which are also responsible of commercializing these GM plants. Anyhow, this represents

11227-574: The same chemical properties as petroleum-based diesel. It does not require new engines, pipelines or infrastructure to distribute and use, but has not been produced at a cost that is competitive with petroleum . Gasoline versions are also being developed. Green diesel is being developed in Louisiana and Singapore by ConocoPhillips , Neste Oil , Valero , Dynamic Fuels, and Honeywell UOP as well as Preem in Gothenburg, Sweden, creating what

11336-442: The sugars, distillation and drying. The distillation process requires significant energy input to generate heat. Heat is sometimes generated with unsustainable natural gas fossil fuel, but cellulosic biomass such as bagasse is the most common fuel in Brazil, while pellets, wood chips and also waste heat are more common in Europe. Corn-to-ethanol and other food stocks has led to the development of cellulosic ethanol . Methanol

11445-534: The three competing genes ( gab D, ybg C, and tes B) that affect the biosynthesis pathway of 1,4-butanediol. Consequently, the yield of 1,4-butanediol significantly increased from 0.9 to 1.8 g/L. Environmental biotechnology includes various disciplines that play an essential role in reducing environmental waste and providing environmentally safe processes, such as biofiltration and biodegradation . The environment can be affected by biotechnologies, both positively and adversely. Vallero and others have argued that

11554-542: The time, testing is used to find changes that are associated with inherited disorders. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder . As of 2011 several hundred genetic tests were in use. Since genetic testing may open up ethical or psychological problems, genetic testing is often accompanied by genetic counseling . Genetically modified crops ("GM crops", or "biotech crops") are plants used in agriculture ,

11663-570: The total company value of pharmaceutical biotech companies worldwide were active in Oncology with Neurology and Rare Diseases being the other two big applications. Pharmacogenomics (a combination of pharmacology and genomics ) is the technology that analyses how genetic makeup affects an individual's response to drugs. Researchers in the field investigate the influence of genetic variation on drug responses in patients by correlating gene expression or single-nucleotide polymorphisms with

11772-426: The very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial biowaste . Biofuels are mostly used for transportation, but can also be used for heating and electricity. Biofuels (and bioenergy in general) are regarded as a renewable energy source. The use of biofuel has been subject to criticism regarding

11881-507: The world's crop lands were planted with GM crops in 2010. As of 2011, 11 different transgenic crops were grown commercially on 395 million acres (160 million hectares) in 29 countries such as the US, Brazil , Argentina , India , Canada, China, Paraguay, Pakistan, South Africa, Uruguay, Bolivia, Australia, Philippines, Myanmar, Burkina Faso, Mexico and Spain. Genetically modified foods are foods produced from organisms that have had specific changes introduced into their DNA with
