Production of biosurfactants by bacteria collected in soil contaminated by diesel oil on the Antarctic Continent

Currently, the whole world strives for a sustainable development to avoid depletion of natural resources. Therefore, search new biotechnological products such as biosurfactants has generated interest due its low toxicity, biodegradability and ecological acceptability. Furthermore, have several applications emulsification, wettability, foaming, cleaning, reduction crude oil viscosity. The objective this work was identify bacteria collected in Antarctica evaluate their capacity produce biosurfactants. In study, diesel contaminated soil around Comandante Ferraz Antarctic Station were identified (Rhodococcus erythropolis, Rhizobium radiobacter, Microbacterium liquefacien, Pseudomonas libanensis veronii) analyses carried out confirm whether these Interestingly, compounds isolated from showed droplet propagation reduced surface tension water, which are properties carbohydrates molecular composition. Given findings, species potential application areas, bioremediation environments by cosmetic personal care emulsifier. addition, use waste carbon source becomes an attractive alternative because it reduces environmental contamination cost.
