A bacterial strain that assimilates fucoidan from Cladosiphon okamuranus as sole carbon source was isolated as Luteolibacter algae H-18. It was found that it degraded fucoidan by intracellular enzymes, and that the degradation reactions were catalyzed by multiple enzymes. One enzyme, designated fraction B, was established to exhibit the deacetylation reaction of fucoidan. Other enzyme(s), designated fraction A, catalyzed the reaction(s) lowering the molecular weight of fucoidan.
