摘要：
Marine waste extract was tested as nitrogen rich growth substrate for Sulfate Reducing Bacteria (SRB). A liquid extract was prepared from marine waste and characterized. The extract contained 14.541 g L-1 of nitrogen, 12.345 g L-1 of total organic carbon, 90.322 g L-1 of protein and 1.48 mg L-1 of magnesium. The extract supplemented medium exhibited improved performance as compared to Postgate B medium for their ability to promote the growth of SRB. It supported 95 % sulfate reduction at a rate upto 21 mg L-1 h(-1) and 1.21x10(13) cells/ml of SRB population. This indicates that the potential exists for the use of marine waste extract as growth substrate for SRB.
