The purification of organic compounds is tedious unlike inorganic compounds because large number of them decomposes on heating, some are sensitive to other reagents and resist the solvent action of water. Depending on the nature of the compound and nature of impurities present, various methods can be employed for the purification of a particular compound. … Read more

by

Nutritional environment regulates the bacterial growth. When a bacterium inoculated in a suitable liquid medium is incubated, its growth leads to an increase in the number of bacterial cells which follows a definite course. When bacterial count of such culture is determined periodically and plotted, a curve is obtained i.e. called growth curve. The growth … Read more
