FIELD: chemistry.
SUBSTANCE: described is a novel cyclodecapeptide antibiotic laterocin, produced by the Brevibacillus laterosporus VKPM V-10531 strain. Laterocin is a white amorphous solid substance of formula [cyclo-(L-Val-L-Orn-L-Leu-D-Tyr-L-Pro-L-Phe-D-Phe-L-Asn-L-Asp-L-Met-)] and molecular weight 1240.6 Da. Laterocin has algicidal (antagonistic) effect on various types of microalgae, particularly blue-green algae Nostoc, Anabaena, Microcystis aeruginosa.
EFFECT: biologically active compound laterocin can be used as an agent for inhibiting growth of blue-green microalgae.
