Metal Tolerance in Halotolerant Bacteria

Scientific Study from the year 2012 in the subject Biology - Micro- and Molecular Biology, Nirma University (Institute of Science), language: English, abstract: Five halotolerant bacteria were isolated from saline soil of Gujarat. Their identification and characterization with respect to optimum pH and salt concentration, and metal tolerance was carried out. Among all isolates Virgibacillus marismortui exhibited better metal tolerance/resistance. In certain cases stimulatory effect of metal ions on growth was also observed. Such organisms can serve as a good model for study of stress response among prokaryotes, and can also be explored for their potential of bioremediation of metal polluted saline sites with alkaline pH.
