Abstract
Keratin found in human nails is a eukeratin [1]. It is degraded by keratinase produced by bacteria like Bacillus sp. Degradation
of human nails was brought about by soil inhabiting bacteria isolated from soil samples of Melmaruvathur, Tamil Nadu, India. The
growth curve of the bacteria was determined. Inhibition was studied using various mixtures of lime juice, salt and ginger extract in
alcohol. The growth of the bacteria producing keratinase isolated by us is found to be inhibited by a mixture of lime juice, salt and
alcohol. It was also found that ethanol was more effective than methanol in its inhibitory action [2].
