Molecular Characterization and Phylogenetic Analysis of Cellulase Producing Streptomyces griseorubens ( Strain St-1 ) Isolated from Indian Soil

Abstract

The present study was aimed at characterization of the cellulose degrading actinomycete strain St-1, isolated from soil samples of Patna region in India, on the basis of morphological, cultural, physiological and molecular characterization. Based on morphological and analysis of 16S rRNA sequence, the strain St-1 was identified as Streptomyces griseorubens (Accession no. AB 184139). The strain was able to grow in a wide range of pH (5-11) and temperature (4-45 0 C) with 7 and 28 o C being the optimum pH and temperature, respectively. The strain was able to survive at up to 6 % NaCl concentration through the optimum growth was observed at 1% NaCl concentration.
