Aerobic biogenesis of selenium nanospheres by Bacillus cereus isolated from coalmine soil.

ABSTRACT:

Background

Microorganisms that are exposed to pollutants in the environment, such as metals/metalloids, have a remarkable ability to fight the metal stress by various mechanisms. These metal-microbe interactions have already found an important role in biotechnological applications. It is only recently that microorganisms have been explored as potential biofactories for synthesis of metal/metalloid nanoparticles. Biosynthesis of selenium (Se 0) nanospheres in aerobic conditions by a bacterial strain isolated from the coalmine soil is reported in the present study.

Results

The strain CM100B, identified as Bacillus cereus by morphological, biochemical and 16S rRNA gene sequencing [GenBank:GU551935.1] was studied for its ability to generate selenium nanoparticles (SNs) by transf
