Removal of chromium by Staphylococcus saprophyticus subsp. bovis strain 1

摘要: The present study was taken up to carry out the removal of chromium by bacteria. Chromium is a heavy metal which concern as it causes toxicity in both plants and animals. The tanneries are a major source release into the water bodies, hence this aimed at identifying the potential chromium-tolerant bacterium studying the bacterium for its maximum tolerance removal capacity. A total 20 samples each soil industrial effluents were collected from the Peenya area, Bangalore, India. The bacterial isolates screened resistance supplementing the nutrient media with 300 µg/ml chromium. The  growth the  bacteria measured terms O.D. 670 nm. The isolates further increasing the concentration 300 3000 µg/ml. The isolate S105c showed better compared other identified Staphylococcus saprophyticus  subsp. bovis strain 1 based on 16S rRNA sequencing. Optimization temperature, pH, carbon sources, nitrogen sources carried S. saprophyticus subsp. 1.  Atomic absorption spectrophotometric analysis the mineral salts medium supplemented chromium. Out 40 effluent collected, a total 51 obtained. isolates, 7 gave the highest values the presence S10-5c 3000 µg/ml S.  able remove 2% the medium the end 24 hours under optimized conditions. It can be concluded that the organism used effluents.
