Chromate detoxification potential of Staphylococcus sp. isolates from an estuary.

Chromium (Cr) pollution is an emerging environmental problem. The present study was carried out to isolate Cr-resistant bacteria and characterize their Cr detoxification and resistance ability. Bacteria screened by exposure to chromate (Cr) were isolated from Mandovi estuary Goa, India.

Response to chromate challenge by marine sp. NIOMR8 evaluated by differential protein expression.

Liquid Chromatography-Mass Spectrometry-Quadrupole Time of Flight (LC/MS QToF) protein profiling of marine-derived NIOMR8 was carried out to evaluate proteins conferring chromate (Cr) resistance and possible metabolic pathways that were altered as a result. Expressional (up or down-regulation) responses to varying Cr (0, 50, 100, 150, and 200 µg mL) concentrations varied, with as many as 346 proteins identified. Most number of proteins-their numbers in parentheses-were up-regulated when grown in medium with 50 µg mL (162) and, down-regulated in medium with 100 (281) or 200 µg mL Cr (280).

Improved Sprouting and Growth of Mung Plants in Chromate Contaminated Soils Treated with Marine Strains of Species.

Marine bacteria possess a wide variety of bioremediation potential which is beneficial environmentally and economically. In this study, bacterial isolates from marine waters were screened for tolerance and growth in high concentrations of chromate (Cr). Two isolates, capable of tolerating Cr concentrations 300 µg mL or higher, and found to completely reduce 20 µg mL Cr were grown in Cr (50 and 100 mg kg) spiked garden soil.

Efficient bioremediation of tannery wastewater by monostrains and consortium of marine Chlorella sp. and Phormidium sp.

This study evaluated the bioremediation potential of two marine microalgae Chlorella sp. and Phormidium sp., both individually and in consortium, to reduce various pollutants in tannery wastewater (TW).
