- What is industrial microbiology?
Industrial microbiology refers to a subdivision of applied microbiology where microorganisms are utilized in specific industrial processes. The procedures are the generation of high-worth products like electricity, fuels, chemicals, and drugs.
- What is a bioreactor?
A bioreactor is a gadget used for growing organisms like cells, animals, bacteria, or yeast under a controlled state.
- Which microorganisms are used for the production of vitamin B12?
A limited number of bacteria are recognized for their massive production of vitamin B12; they are Propionibacterium freudenreichii, Bacillus megaterium, and Pseudomonas denitrificans.
- Which is the organism used to produce riboflavin?
Escherichia coli (Bacher et al., 1996), and Bacillus subtilis (Perkins and Pero, 2002)
- How are antibiotics produced?
Antibiotics are generated through an industrial process of fermentation, where the microorganism that acts as a source is grown in a large container (110,000 – 160,000) with a liquid growth intermediate.
- What is fermentation technology?
This refers to the field of technology that involves the utilization of enzymes and microorganisms for the generation of compounds that contain application in the food industry, chemical, pharmaceutical, material, and energy.
- Brief about microbes used in food production?
Nature utilizes microorganisms to perform the process of fermentation, and for many years man has used bacteria, moulds, and yeast to make products of food like cheese, yoghurt, vinegar, wine, etc.
