| Abstract | PAHs are widespread in aquatic environments and are major contributors to marine pollution. In the present study, a deep-sea bacteria Brevibacterium atlanticum was isolated from the depth of 1500 m deep-sea sediment of Bay of Bengal was capable of degrading pyrene. The response of bacteria towards degradation for the free and immobilized cells was studied. An immobilization study was carried out using coco peat. The growth rate of B. atlanticum for free cells was significantly different from the growth for coco peat immobilized cells. The degradation percentage reached 83.4 and 91.2% for free and immobilized cells respectively within a retention period of 8 days. The presence of 1, 2-Benzenedicarboxylic acid in GC-MS analysis and functional groups like carboxylic acid, aliphatic C-H group, C-N stretch of amide groups in FTIR confirmed the organism B. atlanticum follows phthalic acid degradation pathway. The enhanced biodegradation of pyrene in cocopeat-immobilized cells indicate the high potential of hydrocarbonoclastic cells immobilized agro-residues for bioremediation of hydrocarbon contaminated marine sites. |
