Biotechnology major is a second-class doctoral program independently established by Nanjing Agricultural University in 2002 under the first-class discipline of national doctoral crop science. The major's main related scientific and technical fields are microbiology, botany, biochemistry and molecular biology, and its main research fields are environmental biotechnology, microbial degradation of pollutants, microbial fermentation and enzyme engineering, genomics, protein genomics and immunology technology. It has made remarkable achievements and distinctive features in environmental pollution control and remediation, plant biochemistry, modern immune technology, microbial fermentation technology and product development. There are nearly 4 doctoral supervisors. Relying on the key open laboratory of agricultural environmental microbial engineering and the key open laboratory of animal disease diagnosis and immunization of the Ministry of Agriculture, this subject has good scientific research conditions. The employment destination of graduate students is mainly scientific research, teaching, management and enterprise units.

Main disciplines of biotechnology: main courses of biology: microbiology, cell biology, genetics, biochemistry, molecular biology, genetic engineering, cell engineering, microbial engineering, biochemical engineering, downstream technology of bioengineering, enzyme engineering, fermentation engineering equipment, etc. Main practical teaching links: including teaching practice, production practice and graduation thesis (design). , usually arranged in 10-20 weeks. Length of study: four years Degree awarded: Bachelor of Science.

Biological engineering, biological science and biotechnology are all similar. Specifically, the school you attend is slightly different from the class you attend, but it is all basic knowledge of biology, which is useless. Biomedical engineering is better, close to medicine and engineering, involving biomaterials and so on. These majors were not distributed in great detail until graduate students graduated.
