During an initial screening in samples of bilge water, four bacterial strains capable to oil degrade have been isolated. Two strains, named isolates BW-1 and BW-2, were clustered with Acinetobacter genus (a similarity of 100% and 99%, respectively) and two strains, named isolates BW-3 and BW-4 were related to Rhodococcus genus (a similarity of 99% and 98%, respectively). During growth (8?days) in M9 medium with Arabian Light Crude Oil (1%, w/v), measures of microbial abundance, surface tension, emulsification index (E 24) and oil degradation, were carried out. During cultivation, isolates BW-1 and BW-2 are good biosurfactant producers and about 80% of crude oil is degraded. Also, isolates BW-3 and BW-4 show, during cultivation, production of biosurfactant but only 40% of total oil is degraded. Data obtained give important results in order to utilise these isolate native bilge waste microorganisms in the studies/process of bioremediation. 相似文献

Effect of a Bioemulsificant Exopolysaccharide (EPS2003) on Abundance and Vitality of Marine Bacteria
S. Cappello A. Crisari M. Hassanshahian M. Genovese S. Santisi M. M. Yakimov 《Water, air, and soil pollution》2012,223(7):3903-3909
The aim of this work has been to analyze the effects of a bioemulsificant exopolysaccharide (EPS2003) on the abundance and vitality of natural marine microbial population. Harbor seawater microcosms, supplemented with bioemulsificant EPS2003 (at different concentrations), were monitored over 20?days. The microbial community dynamic was analyzed by measurement of bacterial density (total and cultivable count) and vitality (live/dead count and total RNA amount). The results obtained show that addition of bioemulsificant (also at different concentrations), as sole carbon source, supported growth of the indigenous bacterial populations and revealed that this substance is optimal for use in the participations of recovery of environment polluted from oil. In comparison, an analysis with commercial dispersant was also carried out. 相似文献
