Bioactivity of Biomass and Crude Exopolysaccharides Obtained by Controlled Submerged Cultivation of Medicinal Mushroom .

The aim of this study is to characterize the bioactivity of mycelial biomass and crude exopolysaccharides (EPS) produced by NBIMCC 8939 and to reveal its nutraceutical potential. The EPS (1.58 g/L) were isolated from a culture broth.

Isolation, Characterization and Amino Acid Composition of a Bacteriocin Produced by Strain BM47.

Members of the bacterial genus are known as producers of a broad spectrum of antibiotic compounds of proteinaceous nature that possess inhibitory activity against different saprophytic and pathogenic microorganisms. In the current research, a peptide synthesized by strain BM47, previously isolated from a natural thermal spring in Bulgaria, was identified and characterized as a bacteriocin. antimicrobial screening of the crude bacteriocin substance of BM47 showed activity against the plant pathogenic fungi , , sp.
