“…Bacteria in the genus Gordonia have been isolated from various petroleum hydrocarbon-contaminated sites, including oily seawater (Arenskötter et al, 2004;Brito et al, 2006;Quatrini et al, 2008;Shen et al, 2008). Earlier reports demonstrated that Gordonia persist in severe conditions and possess special cellular physiology, including high cell surface hydrophobicity, emulsifi cation activity and EPS synthesis, to enhance hydrophobic substrate uptake (Arenskötter et al, 2004;Franzetti et al, 2009;Fusconi et al, 2006Fusconi et al, , 2010. Thus, it is possible to use Gordonia sp.…”

“…There have been numerous studies on the washing of crude oil contaminated soil with surfactants but their purpose was only to clean the soil and not to recover the oil (Urum et al, 2006;Franzetti et al, 2009). After these treatments, further treatment is generally needed for oil-containing wastewater.…”

“…For example, Pseudomonas aeruginosa produces rhamnolipids, and Bacillus subtilis produces a lipopeptide called surfactin (11). Franzetti and colleagues (6) demonstrated that the crude oil removal by bioemulsans produced by Gordonia sp. BS29 strain was comparable to the rhamnolipid one in the same experimental conditions and the promising use of this bioemulsans as washing agents for remediation of hydrocarbon-contaminated soils.…”

The contamination of ecosystems with heavy metals is an important issue in current world and remediation technologies should be in according to environmental sustainability concept. Bioemulsifier are promising agents to be used in metal removal and could be effective to many applications in environmental industries. The aims of this work was screening the potential production of bioemulsifier by microorganisms isolated from an oil contaminated mangrove, and evaluate cadmium and zinc removal potential of those strains from a hazardous industrial residue. From that, bioemulsifier-producing bacteria were isolated from urban mangrove sediments. Four isolates were identified as Microbacterium sp by 16S rRNA analysis and were able to reduce up to 53.3% of culture medium surface tension (TS) when using glucose as carbon and energy source and 20.2% when sucrose was used. Suspensions containing bioemulsifier produced by Microbacterium sp. strains show to be able to remove cadmium and zinc from contaminated industrial residue, and its ability varied according carbon source. Significant differences in metal removal were observed by all strains depending on the carbon source. When glucose was used, Cd and Zn removal varied from 17 to 41%, and 14 to 68%, respectively. However, when sucrose was used it was observed only 4 to a maximum of 15% of Cd removal, and 4 to 17% of Zn removal. When the same tests were performed after ethanol precipitation, the results were different: the percentages of removal of Zn (7-27%) and Cd (14-32%) were higher from sucrose cultures. This is the first report of heavy metals removal by bioemulsifier from Microbacterium sp.
