Endoglucanase gene of M42 aminopeptidase/endoglucanase family from thermophilic Bacillus sp. PW1 and PW2 isolated from Tattapani hot spring, Himachal Pradesh, India.

ABSTRACT:

Background

Thermostable cellulases are in constant demand for several biotechnological applications. Two thermophilic bacterial strains PW1 and PW2 isolated from Tattapani hot spring were found to have cellulolytic activity. Subsequently, PW1 and PW2 were identified and mined for genes encoding cellulase activity.

Results

Sequencing of the 16S rDNA of PW1 and PW2 identified them as Bacillus sp. PW1 (Acc no. KU711837) and Bacillus sp. PW2 (Acc no. KU711838), respectively, which clustered in the clades containing thermophilic members of Bacillus sp. and Geobacillus species. Phylogenetic analysis revealed that despite the morphological and sequence identities, Bacillus sp. PW1 and Bacillus sp. PW2 are different at the genetic level. The cellulase genes (~ 1.1 kb) of the two bac
