Talk about the development trend of modern microbiology.

the emergence and development of biotechnology

biotechnology, as a high-tech technology, was born in the early 197s with the invention and application of DNA recombination technology and lymphocyte hybridoma technology. Over the past 3 years, the rapid development of biotechnology has opened up broad prospects for the development of medical industry, pharmaceutical industry, agriculture, animal husbandry and environmental protection industry, which has greatly improved people's lives. All countries in the world have identified biotechnology as the key technology and emerging industry for the development of science and technology in the 21st century.

China's biotechnology industry has been widely used in medicine, agriculture, food, environmental protection, light chemical industry, energy and other fields since it started in the early 198s. Enterprises engaged in the development of biotechnology products have mushroomed. From 1985 to 2, product sales increased by 75.99 times. The average annual growth rate is 33.58%. In 2, the output value of China's biotechnology industry reached 2 billion yuan, especially the genetically engineered pharmaceutical industry developed rapidly. In 1996, the sales of genetically engineered drugs and vaccines reached 22 million yuan, reaching 2.28 billion yuan in 2. The average annual growth rate is 79.42%. In recent years, the average annual growth rate of biotechnology industry has remained above 2%.

There are about 5 enterprises involved in modern biotechnology in China, with more than 5, employees, including more than 3 enterprises involved in pharmaceutical biotechnology and more than 2 involved in agricultural biotechnology. Some newly-established biotechnology companies are on the rise. Nearly 1 new companies are added every year. More than 2 biotechnology parks have been established in Beijing, Shanghai, Fuzhou, Guangzhou, Shenzhen and other places, and some preferential policies have been introduced to give comprehensive support to biotechnology enterprises in taxation, finance, talent introduction, import and export, etc. At present, a large number of new enterprises have been cultivated, which plays a leading role in the development of biotechnology in China.

With the rapid development of biotechnology industry in China and even around the world, it is of great significance to biotechnology enterprises. This is probably the largest piece, and it can cultivate strains suitable for industrial raw material production, antibiotics, soil improvement, environmental protection, mineral smelting and other fields.

2. Microbial membrane structure, mainly the function and structure of membrane proteins;

3. Microbial metabolic network, or metabolic engineering;

4. Nucleoid structure and gene expression regulation;

5. Traditional taxonomy may be declining, and molecular systematics will be popular.
