“…Another approach for screening potential biosurfactant producing microbes is the estimation of emulsifying activity. In this study, EI24 of BF40 strain was less than 45.0% in all treatments (Figure 2), which was much lower than the efficient emulsification activity of 65.0% reported by Bento et al (2005). Salt concentrations had a significant effect on EI24, which decreased sharply with NaCl concentrations greater than 1.0%.…”

An ideal strain for crude oil degradation in saline soils would be one with high salt-tolerance. A novel bacterial strain, Serratia sp. BF40, was isolated from crude oil contaminated saline soils. Its salt-tolerance, surface activity and ability to degrade crude oil in saline soils were evaluated. It can grow in liquid culture with NaCl concentration less than 6.0%. Its surface activity characterized as an efficient surface tension reduction, was significantly affected by salinity above 2.0%. BF40 inoculation could decrease surface tension of soil solutions and facilitate crude oil removal in soils with 0.22-1.20% salinity, but the efficiency was both significantly lower than its biosurfactant addition. The BF40 strain has a high potential for biodegradation of crude oil contaminated saline soils in view of its high surface activity and salt-tolerance, which is the first report of biosurfactant producing by the genus Serratia for petroleum degrading. We suggest that biosurfactant addition is an efficient strategy. Simultaneously, the growing status of the strain and how to boost its surface activity in saline soils should deserve further studies in order to achieve a continuous biosurfactant supply.

“…The degradation percentage was determined according to [26]. This was calculated by subtracting the residual diesel after treatment from the diesel content of untreated sample and divided by the diesel of the untreated sample multiplied by one-hundred.…”

“…Since the 1940's, the susceptibility of hydrocarbons to microbial degradation is well documented (Zobell 1946) .The extent of the degradation varies according to their chemical structures. Previous studies on bioremediation have yielded good results for the decontamination of diesel oil contaminated soil in temperate climates (Huang et al 2004;Ghazali et al 2004;Bento et al 2005;Riffaldi et al 2006). However, the bacterial diversity of tropical ecosystems is less explored.…”
