Abstract: A group of microorganisms, composed of Lactobacillus sp. strain K03D08, Bacillus sp. strain K03B01 and Kazachstania sp. strain K03K02G, which allows the hydrolysis of casein in different dairy products and the production of short-chain fatty acids and hydroxylated short-chain fatty acids; a process for obtaining a casein-free dairy derivative and enriched in short-chain fatty acids and hydroxylated short-chain fatty acids using the aforementioned microorganisms; compositions containing the microorganisms; and the production method of each of the microorganisms.

Abstract: 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.
