BREVIBACILLUS LATEROSPORUS BACTERIUM STRAIN INHIBITING AND PREVENTING DEVELOPMENT OF MICROPHYTIC ALGAE OF VARIOUS TAXONOMIC TYPES

摘要

FIELD: agriculture.;SUBSTANCE: Brevibacillus laterosporus "ВКПМ" В-9405 bacterium strain is separated by means of multistage selection from the natural Brevibacillus laterosporus "ВКПМ" В-8287 strain. The algicide activity is estimated by the strain lytic action on microalgae defining residual optical density (OD). OD is 10.1%. The strain algistatic activity is estimated by defining optical density. The optical density is 1.950.;EFFECT: strain is capable of algicide and algistatic activity in relation to microphytic algae.;5 tbl, 5 ex
