Frequently asked questions
What microbe-to-product matches are tested most?
Lactobacillus in curd formation, Saccharomyces cerevisiae in bread/wine fermentation, and Penicillium/Streptomyces as antibiotic sources are the most frequently asked matches.
Is sewage treatment tested in technical detail?
At a basic level — knowing the primary, secondary (activated sludge), and anaerobic sludge digestion stages, and the role of BOD as a pollution indicator, is usually sufficient.
How does this chapter relate to Biotechnology?
It covers traditional/industrial microbiology, while Biotechnology covers genetic engineering — NEET treats them as related but distinct question pools.
