MTCC 13131: An Amide-Hydrolyzing Thermophilic Bacterium Isolated from a Hot Spring of Manikaran.

UNLABELLED

MTCC 13131, an amide hydrolyzing bacteria was isolated from a hot spring in Himachal Pradesh and identified through 16S rRNA gene sequence analysis. The amidase derived from this bacterium exhibited hydrolyzing catalytic ability against aliphatic and aromatic amides. The isolate was characterized for morphological and biochemical properties. Further, the production of amidase enzyme from this isolate was evaluated using approach of one-variable-at-a-time and response surface method. The Response Surface Methodology based study indicated the importance of nitrogen sources and growth period for amidase production. Optimal production was achieved at a temperature 55 °C, and production pH 7.5 in the production medium comprising diammonium hydrogen phosphate (0.4%), peptone (0.45%) and yeast extract (0.3%). The wide substrate affinity of the strain suggests its potential role in biotransformation of amides to corresponding acids of industrial significance along with its strong capacity to degrade the toxic amide in polluted environmental samples.
