Studies on Keratinolytic Activity of Alkaline Proteases from Halophilic Bacteria
Alkaline proteases producing halophilic bacteria isolated from Sambar Lake, Rajasthan were investigated for keratinolytic activity. The aim of this study was to optimize culture conditions for maximum enzyme production as well as characterization of proteases with keratinolytic action. Casein was used as sole carbon and nitrogen source for alkaline protease production at 37°C and 150 rpm. Highe...
متن کاملGrowth factor requirements of halophilic bacteria.
Despite the wide interest in halophilic bacteria for practical and scientific reasons, very little has been done on their organic nutritional requirements, although their inorganic requirements have received considerable attention (Robinson, 1950; Schoop, 1935). Various complex media utilizing fish infusions (Gibbons, 1936; Harrison and Kennedy, 1922; Lochhead, 1934), beef and yeast extracts or...
متن کاملProteolytic enzymes from extremely halophilic bacteria.
Halobacterium strains produce a truly extracellular proteinase which degrades gelatine and casein. It has a pH optimum of about 8 and depends upon divalent cations and a high concentration of NaCl or KC1 for activity and stability. Proteolytic enzymes were also found in cell homogenates obtained by ultra sonic treatment. A caseinolytic enzyme, probably different from the extracellular one, is a...
