Biotechnology
In 1917, Chaim Weizmann used a pure microbiological culture to manufacture acetone from corn starch using Clostridium acetobutylicum. This process met the United Kingdom's desperate need for explosives during World War I. Long before this industrial moment, early farmers in Mesopotamia and Egypt selected crops with the highest yields to support growing populations. These ancient societies also utilized fermentation to produce beer by converting grain starch into sugar and then alcohol. Lactic acid fermentation created preserved foods like soy sauce and leavened bread thousands of years ago. Louis Pasteur did not fully understand these biological processes until his work in 1857. Humans have practiced selective breeding for thousands of years to improve livestock and crop production. Charles Darwin later added scientific observations about changing species to this body of knowledge.
Modern biotechnology is generally thought to have been born in 1971 when Paul Berg conducted successful gene splicing experiments at Stanford University. Herbert W. Boyer and Stanley N. Cohen significantly advanced the technology in 1972 by transferring genetic material into a bacterium. Their method allowed imported material to be reproduced within the host organism. The commercial viability of the industry expanded on the 16th of June 1980, when the US Supreme Court ruled that a genetically modified microorganism could be patented. This decision involved Indian-born Ananda Chakrabarty working for General Electric. He had modified a Pseudomonas bacterium capable of breaking down crude oil to treat oil spills. The court case Diamond v. Chakrabarty established legal precedents for intellectual property rights in the sector. Biosensor MOSFETs were also developed between 1955 and 1960 at Bell Labs. Leland C. Clark and Champ Lyons invented the first biosensor in 1962.
In 1978 Genentech developed synthetic humanized insulin by joining its gene with a plasmid vector inserted into Escherichia coli bacteria. Previously doctors extracted insulin from the pancreases of cattle or pigs found in abattoirs. These engineered bacteria produce large quantities of synthetic human insulin at relatively low cost. Pharmacogenomics analyzes how an individual's genetic makeup affects their response to drugs. Researchers correlate gene expression or single-nucleotide polymorphisms with drug efficacy or toxicity. This approach promises personalized medicine where treatments are optimized for each person's unique genetics. As of 2011, several hundred genetic tests were in use to identify changes associated with inherited disorders. In 2021 nearly 40% of pharmaceutical biotech company value was active in Oncology. Neurology and Rare Diseases remain other major application areas for these companies.
Commercial sale of genetically modified foods began in 1994 when Calgene marketed its Flavr Savr delayed ripening tomato. Between 1996 and 2011 the total surface area of land cultivated with GM crops increased by a factor of 94. Ten percent of the world's crop lands were planted with GM crops in 2010. By 2011 eleven different transgenic crops grew commercially on farms across twenty-nine countries including Brazil Argentina India and China. Farmers widely adopted GM technology to resist pests and herbicides like Roundup Ready soybeans. The FDA approved the first GM salmon for commercial production and consumption in 2015. A scientific consensus states that currently available food from GM crops poses no greater risk than conventional food. Yet public perception differs significantly from scientific opinion regarding safety. Golden rice is engineered to have higher nutritional content to combat malnutrition in India and other nations.
Industrial biotechnology applies biological processes to create useful products such as chemicals detergents paper pulp textiles and biofuels. Synthetic biology serves as an essential cornerstone due to its financial and sustainable contribution to manufacturing. Scientists re-engineer metabolic pathways of Escherichia coli using CRISPR systems to produce 1,4-butanediol for fiber manufacturing. This process increased yield from 0.9 to 1.8 grams per liter through specific gene modifications. The Department of Energy estimates ethanol usage could reduce US petroleum-derived fuel consumption by up to thirty percent by 2030. Rising demand for biofuels benefits the biotechnology sector significantly. Companies develop genetically modified seeds that resist pests and drought to boost farm productivity. These innovations help move the economy away from petrochemical-based production toward renewable raw materials.
Regulation of genetic engineering varies between countries with marked differences occurring between the United States and Europe. The European Union differentiates between approval for cultivation within its borders and approval for import and processing. Only a few GMOs have been approved for cultivation in the EU while many are allowed for import and processing. The EUginius database helps companies and authorities find precise information on GMO presence and detection. Members of the public are much less likely than scientists to perceive GM foods as safe. Economic concerns arise because these organisms are subject to intellectual property law. Some nations ban or restrict GM crops entirely while others permit them with varying degrees of regulation. The legal status of GM foods depends on intended use such as food versus non-food applications. Ongoing debate continues regarding coexistence of GM and non-GM crops across global markets.
Common questions
When did Chaim Weizmann use microbiological culture to manufacture acetone?
Chaim Weizmann used a pure microbiological culture to manufacture acetone from corn starch in 1917. This process utilized Clostridium acetobutylicum to meet the United Kingdom's need for explosives during World War I.
