Q. Explain microbiology of water?
Ans. Unlike air, natural waters contain their natural flora, as well as, microorganisms from soil and possibly from animals and sewage. The kinds of bacteria in natural water are chiefly species of Pseudomonas, Chromobacterium, l'roteus, Micrococcus, Bacillus, Streptococcus, Enterobacter and Escherichia. The microbial load of any water depends upon, whether it is stream water, stored water or ground water. Stored water will have more number of microbes than ground water.
