Biotechnology is the industrial production of penicillin pdf of scientific and engineering principles to the processing of materials by biological agents to provide goods and services.

From its inception, biotechnology has maintained a close relationship with society. Yet the formation of a new field, genetic engineering, would soon bring biotechnology to the forefront of science in society, and the intimate relationship between the scientific community, the public, and the government would ensue. The field of genetic engineering remains a heated topic of discussion in today’s society with the advent of gene therapy, stem cell research, cloning, and genetically modified food. Biotechnology arose from the field of zymotechnology or zymurgy, which began as a search for a better understanding of industrial fermentation, particularly beer. Beer was an important industrial, and not just social, commodity. In late 19th-century Germany, brewing contributed as much to the gross national product as steel, and taxes on alcohol proved to be significant sources of revenue to the government.

The heyday and expansion of zymotechnology came in World War I in response to industrial needs to support the war. Max Delbrück grew yeast on an immense scale during the war to meet 60 percent of Germany’s animal feed needs. With food shortages spreading and resources fading, some dreamed of a new industrial solution. The Hungarian Károly Ereky coined the word “biotechnology” in Hungary during 1919 to describe a technology based on converting raw materials into a more useful product. He built a slaughterhouse for a thousand pigs and also a fattening farm with space for 50,000 pigs, raising over 100,000 pigs a year. This catchword spread quickly after the First World War, as “biotechnology” entered German dictionaries and was taken up abroad by business-hungry private consultancies as far away as the United States.

In Chicago, for example, the coming of prohibition at the end of World War I encouraged biological industries to create opportunities for new fermentation products, in particular a market for nonalcoholic drinks. The belief that the needs of an industrial society could be met by fermenting agricultural waste was an important ingredient of the “chemurgic movement. Fermentation-based processes generated products of ever-growing utility. In the 1940s, penicillin was the most dramatic. While it was discovered in England, it was produced industrially in the U.

Penicillin was viewed as a miracle drug that brought enormous profits and public expectations. Even greater expectations of biotechnology were raised during the 1960s by a process that grew single-cell protein. When the so-called protein gap threatened world hunger, producing food locally by growing it from waste seemed to offer a solution. It was the possibilities of growing microorganisms on oil that captured the imagination of scientists, policy makers, and commerce. MIT to provide an acceptable and exciting new title, avoiding the unpleasant connotations of microbial or bacterial. The “food from oil” idea became quite popular by the 1970s, when facilities for growing yeast fed by n-paraffins were built in a number of countries.

First, the price of oil rose catastrophically in 1974, so that its cost per barrel was five times greater than it had been two years earlier. Second, despite continuing hunger around the world, anticipated demand also began to shift from humans to animals. This was particularly vocal in Japan, where production came closest to fruition. For all their enthusiasm for innovation and traditional interest in microbiologically produced foods, the Japanese were the first to ban the production of single-cell proteins.

The Japanese ultimately were unable to separate the idea of their new “natural” foods from the far from natural connotation of oil. 8 paraffin-fed-yeast plants that the Soviet Ministry of Microbiological Industry had by that time. In the late 1970s, biotechnology offered another possible solution to a societal crisis. The escalation in the price of oil in 1974 increased the cost of the Western world’s energy tenfold. 10 percent alcohol added, as an answer to the energy crisis.

Biotechnology seemed to be the solution for major social problems, including world hunger and energy crises. In the 1960s, radical measures would be needed to meet world starvation, and biotechnology seemed to provide an answer. However, the solutions proved to be too expensive and socially unacceptable, and solving world hunger through SCP food was dismissed. In the 1970s, the food crisis was succeeded by the energy crisis, and here too, biotechnology seemed to provide an answer. The origins of biotechnology culminated with the birth of genetic engineering. There were two key events that have come to be seen as scientific breakthroughs beginning the era that would unite genetics with biotechnology.

Genetic engineering proved to be a topic that thrust biotechnology into the public scene, and the interaction between scientists, politicians, and the public defined the work that was accomplished in this area. Technical developments during this time were revolutionary and at times frightening. In December 1967, the first heart transplant by Christian Barnard reminded the public that the physical identity of a person was becoming increasingly problematic. Responses to scientific achievements were colored by cultural skepticism. Scientists and their expertise were looked upon with suspicion. In 1968, an immensely popular work, The Biological Time Bomb, was written by the British journalist Gordon Rattray Taylor. The author’s preface saw Kornberg’s discovery of replicating a viral gene as a route to lethal doomsday bugs.
