Biossurfante and use of same in remediation of soils impacted by oil.

摘要

Biossurfatante and use of same in remediation of soils impacted by oil is described biossurfatante consisting of culture medium free of microbial cells, resulting from the cultivation of a strain of Pseudomonas aeruginosa isolated from the environment of oil producing raminolipu00eddeos by ferm The guideline conducted under aeration by diffusion of oxygen through the membranes.In batch or fed sodium nitrate and using as a carbon source, glycerol in concentration ranging from 1% to 3% v / v. the biossurfatante is preponderant proportion of raminolipu00eddeos in C ~ 10 ~ C ~ 10 ~, which imparts a higher hydrophobicity at the same. The biossurfatante is applied in the remediation of sandy soils impacted by oil spills.The action of the biossurfatante is similar to that of biossurfatantes commercial concentrates.
