Hii Harshita!
Sertoli cells provide nourishment to the germ cells. This nurses the growing germ cells and helps in the process of spermatogenesis. At the end, they absorb the extra cytoplasm from the newly formed spermatozoa. These cells are activated by FSH hormone.
The microbes used in the formation of vinegar are mainly the acetic acid bacteria. This process is oxidative fermentation. Mainly Acetobacter and Glucanobacter species are seen.
Hope this helps.
Good luck!
