Biochemistry is considered an interdisciplinary subject between biology and chemical engineering. Although China's bio-chemical industry has developed slowly from thousands of years of brewing, making sauce and vinegar, traditional bio-chemicals are also limited to the food industry such as brewing, pharmaceutical industry such as vitamins (vitamin B, vitamin C), antibiotics. (penicillin, streptomycin), and bio-pesticides such as jinggangmycin (control rice blast), qingfengmycin (control rice blast), but since the 1980s, with microbiology, biochemistry, Genetics, cytology and molecular biology, as well as the development and application of modern experimental technology, electronic technology, and computer technology, have greatly developed biotechnology. On the basis of traditional biotechnology, genetic recombination technology, cell fusion technology, and cells have been formed. A large number of modern bioengineering technologies with strong vitality such as technology and bioreactor technology, and gradually applied to the fields of medicine, food, chemical, metallurgy, energy, medicine, agriculture, forestry, animal husbandry, and environmental protection and monitoring, providing human and society Goods and services. In recent years, the status of bio-chemicals in biotechnology is on the rise, and biotechnology is shifting from traditional medicine to agriculture to bio-chemicals.
Compared with the traditional chemical industry, biochemical has the following characteristics:
a. Mainly using renewable resources as the main raw material.
b. The reaction conditions are mild, mostly normal temperature, normal pressure, low energy consumption, good selectivity and high efficiency.
c. Less environmental pollution.
d. Simple equipment and low investment.
e. It can produce high-performance compounds that cannot be produced or are still unknown, and can develop new varieties.
f. High atomic utilization is an ideal green chemical technology.
Traditional biochemistry focuses on the processing of biological resources and produces many useful products by fermentation. Such as MSG, alcohol, amino acids and so on. Now biochemical technology has been widely used in medicine, food, basic organic chemical raw materials, biological pesticides and so on. With the development of modern biotechnology, based on genetic engineering and microbiology engineering as the core, quantitatively modify and utilize the vital functions of organisms at the molecular and cellular levels to make vitamins, hormones, vaccines, biological pesticides, and organisms. Fine chemicals such as surfactants, acrylamides and organic acids have reached new levels.
Deluxe chandeliers can give your home a more noble feeling.
Most of our luxury chandeliers are made of aluminum as the main body and acrylic as the accessories. The whole lamp is basically made of these two materials. The crystal clear acrylic sets off the beauty of the lamp, and the led reflected from the light source makes the whole lamp body more beautiful.
