Use of a bacterium isolated from the genus
The present invention relates to an isolated bacterium from the genus Pseudoalteromonas for its use as a probiotic, the use of said strain as a preservative, cyclolipopeptides which may be obtained from this bacterium, a composition comprising at least such a cyclolipopeptide, as well as to their uses.
1. A method of treatment to improve animal breeding, which comprises the administration of an effective amount of an isolated bacterium Pseudoalteromonas hCg-6 , capable of producing cyclolipopeptides or formula A:
wherein:
R is selected from the group consisting of
(a) alkyl groups comprising between 4 and 20 carbon atoms, except nonyl and undecyl groups;
(b) alkylene groups comprising between 4 and 20 carbon atoms, except undec-4-ylene and tridec-6 -ylene groups;
(c) alkyl groups substituted with an —OH group and comprising between 4 and 20 carbon atoms; and
(d) alkylene groups substituted with an —OH group and comprising between 4 and 20 carbon atoms.
2. The method according to claim 1 , wherein the isolated bacterium is Pseudoalteromonas hCg-6 , a strain deposited according to the Budapest Treaty, on May 22, 2013, at the Collection Nationale de Culture de Microorganismes (CNCM, Paris, France) under the number I-4753.
3. The method of claim 1 , wherein the animal breeding occurs in aquaculture.
4. The method of claim 1 , wherein the animal is a fish, shellfish, crustacean, abalone or oyster.
