  Conditions favourable for fermentation :

1.     Optimum temperature range for fermentation s 25-30 oC. At higher temperature enzymes are coagulated.

2.     Certain inorganic substances, (NH4)2SO4, phosphate etc are added as food for ferment cells.

3.     Solution to be fermented should be dilute.

4.     Substances like boric acid, mercury slats etc. should not be present as they retard fermentation.

5.     Proper aeration should be maintained in fermentation.

Note : The name fermentation has been derived from Latin word ferver meaning to boil, because during fermentation there is lot of frothing due to evolution of CO2 and this gives the appearance of boiling liquid.
