Subterranean Microhabitat Dependent Intra Versus Extracellular Enzyme Secretion Capabilities of Deinococcus radiodurans

Deinococcus radioduransis one of the most yet discovered extremophilic microbe, the isolation of which from the various habitats of Kotumsar cave is always a matter of enticement to discover its ecological economics. In the present work we studied the intra versus extracellular alkaline protease and glucose isomerase secretion capabilities of; KCB21, KCB50, KCB93 isolated from three distinct subterranean niches of Kotumsar cave. The selected niches/zones were the entrance zone, transient zone and the deep inner zone from where the soil sediments were collected to isolate the bacterial strains.The results revealed high extracellular alkaline protease activity from the strain which was isolated from the deeper zones of the cave, whereas no such phenomenon was revealed for glucose isomerase. The possible reason for the obtained results has been discussed.
