Description 1116-1127
In order to examine the bacterial diversity and enzymatic potential, the isolates were screened for the amylolytic, cellulolytic, lipolytic and proteolytic activities using selective media. Significant proportion of the isolates (44%) exhibited lipase activity, while only few (11%) had protease activity. The 16S rRNA gene sequence analysis revealed that most of the isolates related to the genera Bacillus, Acinetobacter, Staphylococcus, Aeromonas, Psychrobacter, Dietzia and Isoptericola. Examined bacteria displayed significant tolerance against varying salt concentrations. Most of the isolates displayed antagonism against 10 selected target organisms. Bacteria were also assessed for their resistance and sensitivity against different antibiotics. Staphylococcus epidermis MJMG8.1 and Dietzia sp. MJMG8.2 grew significantly in the presence of different organic solvents.
