| Abstract |
An attempt has been made to explore the stability of protease enzyme (isolated from Bacillus sp.) by statistical method. More than 100 isolates were screened for extracellular protease activity derived from various potable water samples of Mahabubnagar district, Telangana State, India. The activity of protease is found to be varying from sample to sample, the highest being reported by the isolate from water sample of Kalwakurthy mandal, Mahabubnagar district and therefore was selected for further studies. The 16S rRNA (ribosomal ribonucleic acid) gene sequence of the isolate showed closest similarity with Bacillus sp. and the sequence was submitted to National Center for Biotechnology Information (NCBI) gene bank (accession number GU566359) and the culture was deposited in three international culture deposition centers (KCTC-13725: MTCC-10465: JCM-16713). The present study revealed that, this Bacillus sp. showed a greater amount of protease production with the inherent characters of thermo, alkali and oxidant stability which makes it a potential alternative protease producing strain in various industrial applications.
