| Abstract: | Marine isolates from sea nodules can be
worthy catalysts to explore the possibilities of faster bioleaching of low
index ocean nodules mined from Indian Ocean.
The native microbes were isolated from Indian Ocean Nodules in Artificial Sea water Nutrient Broth at pH
7.0. Organisms have been found to tolerate up to 7% salt concentration. These
species were found to be typically elongated gram positive bacilli and having a
good generation time (0.7-1.3 h). The faster growth kinetics was found to
useful in sequential adaptation on various metal concentrations. Both species exhibited good
resistance towards 1000 ppm Ni (II) concentration; whereas resistance towards
Cu(II) and Co(II) could only been seen at a metal concentration of 100 ppm thereby proving their efficacy in metallurgical applications. |
