摘要: Seven hydrocarbonoclastic new bacterial isolates were isolated from dredged sediments of a river estuary in Italy. The contaminated by shipyard activities since decades, mainly ascribable to the exploitation diesel oil as fuel for recreational and commercial navigation watercrafts. able utilize sole carbon source. Their metabolic capacities evaluated GC-MS analysis, with reference depletion both normal branched alkanes, nC18 fatty acid methyl ester unresolved complex mixture organic compounds. They taxonomically identified different species Stenotrophomonas Pseudomonas spp. combination amplified ribosomal DNA restriction analysis (ARDRA) repetitive sequence-based PCR (REP-PCR) analysis. interest analyzed relation single strains latter multibacterial system. After 6 days incubation mineral medium source, sp. M1 strain depleted 43-46 % Cn-alkane C28 up C30, 70 % 46 % On other hand, NM1 76 % ester, 50 % multispecies system was completely deplete C30 95 % isolates, either system, proposed candidates bioaugmentation bio-based processes decontamination sediments.
