Bacteria products, as the cornerstone of food processing, provide the necessary microbial activity for the production of daily foods such as bread and beer.
Enzyme products, with their efficient and specific catalytic properties, optimize multiple links from food processing to pharmaceutical production.
Metabolite products, whether primary or secondary metabolites, provide humans with rich nutritional and therapeutic resources.
Biotransformation products, with their environmental protection and high efficiency, provide a greener and more sustainable alternative to chemical synthesis.
1. Bacteria products
The core of bacteria products is the bacteria itself, which plays an important role in the production of foods such as bread and beer:
Microbial cells: As food for humans or animals, they provide protein and other nutrients, sometimes called single-cell proteins or bacterial proteins.
Probiotics: These microorganisms help regulate and maintain the health of the human intestine and are beneficial to the digestive system.
2. Enzyme products
Enzyme products are the purified and processed form of biocatalysts. Enzyme preparations are used in food, textile, feed, detergent, papermaking, leather, medicine and other industries. They have the following characteristics:
High catalytic efficiency: Enzymes can significantly increase the speed of chemical reactions.
Specificity: Each enzyme usually only catalyzes a specific chemical reaction.
Mild action conditions: Enzymes work at relatively low temperatures and pressures, reducing the impact on the environment.
3. Metabolite products
Metabolite products are divided into primary and secondary metabolites:
Primary metabolites: Produced during the logarithmic growth period of microorganisms, they are substances necessary for cell growth and maintenance of life activities, including amino acids, nucleotides, proteins, nucleic acids, vitamins, etc.
Secondary metabolites: Produced after the microorganism grows to a certain stage, with complex chemical structures, and may not have obvious physiological functions for the microorganism. This type of product includes antibiotics, toxins, hormones, pigments, etc., and the secondary metabolites produced by different types of microorganisms are different.
4. Biotransformation products
Biotransformation products involve the process of converting one compound into another by microbial cells or the enzymes they produce:
Conversion reaction types: including dehydrogenation, oxidation, hydroxylation, condensation, decarboxylation, amination, deamination or isomerization, etc.
Application examples: converting ethanol into acetic acid, or producing steroids, chiral drugs, etc. through biotransformation processes.
Compared with chemical synthesis, biotransformation usually has fewer steps, milder conditions, less waste and by-products, and is more environmentally friendly.
