Abstract
Aim. Evaluation of the reishi mushroom, Ganoderma lucidum, vegetative mycelium and water extracts of basidiocarps influence on the growth of opportunistic microorganisms. Materials and methods. Antimicrobial activity of vegetative mycelium and water extracts of basidiocarps from two strains of Ganoderma lucidum (Сurtis) P. Karst. ONU F101 and ONU F102 was screened by the agar diffusion method. Bacterial strains of Pseudomonas aeruginosa АТСС 27853, Proteus vulgaris ATCC 6896, Micrococcus luteus ATCC 4698, Bacillus subtilis ATCC 6633, Enterococcus faecalis ATCC 29212 and yeast-like fungus Candida albicans ATCC 18804 were used as the test-objects. Results. It was established that both reishi mushroom strains are able to inhibit the growth of opportunistic microorganisms under cultivation. Activity of water extracts was lower than vegetative mycelium of the fungus. The strains of different origin differ by the level and range of antimicrobial activity. Conclusions. The antimicrobial activity of the ONU F102 G. lucidum strain was lower than the ONU F101’s strain. The water extracts had less active activity compared with vegetative mycelium.
