Abstract

One hundred and forty eight bacterial strains were isolated from ANZALI LAGOON and NEIDASHT SPRING to determine selenooxyanions and TELLURITE reduction ability. Only one strain, identified and called as Bacillus sp. STG-83, was able to tolerate SELENITE and TELLURITE at high concentrations up to 640 mM and 1250 mM, respectively. The strain reduced the oxyanions. Morphological studies of Bacillus sp. STG-83, grown in presence of SELENITE, showed that the cells initially produced dark and condense granules at their surface and after 24 h they formed round bodies, but in the presence of TELLURITE the cells grew longer than their normal size. Bacillus sp. STG-83 was able to reduce 1 mM sodium SELENITE during 32 h but it reduced only 50% of potassium TELLURITE at 1 mM concentration after 104 h. Amount of elemental selenium in the precipitate was measured by Proton Induced X-ray Emission apparatus.The atmospheric gas of cultures was entrapped in gas washing bottle and then analyzed by Hydride Generation Atomic Absorption Spectrophotometery. The result showed that Bacillus sp. STG-83 was able to produce volatile compounds of selenium and tellurium.
