摘要：
The invention discloses a bacterial strain of non pathogenic Cobetia marina useful in aquaculture, corresponding to an isolated Cobetia marina strain, Gram negative, oxidase positive, deposited under registry number CECT N°7764； grows with dibenzothiophene (DBT) as the only carbon source. Also disclosed is a method to obtain a biosurfactant surfactant extract comprising growing strain Cobetia marina (MM1IDA2H-1) CECT N° 7764 in a reactor with liquid growth medium from 24 to 48 hours at a temperature between 10 and 35° C., pH 6 to 8； constant stirring between 100 to 400 rpm and oxygen saturation between 10 to 21%； until obtaining a grown cell culture and extracellular products plus inorganic salts； separating the cells, lyophilizing supernatant, sieve the obtained powder and dry. Further disclosed is a biosurfactant surfactant and uses thereof for treating infectious pathologies in aquaculture； use as additive for paint formulations for submergible surfaces； and use as food additive for fish, for inducing an immune response.
