Antibacterial Activity of Macromycetes Mycelia and Culture Liquid
Krupodorova, Tetiana A.,Barshteyn, Victor Yu.,Zabeida, Elena F.,Pokas, Elena V. The Korean Society for Microbiology and Biotechnol 2016 한국미생물·생명공학회지 Vol.44 No.3
The antibacterial activities of thirty mushroom species belonging to Basidiomycetes and Ascomycetes, cultivated on two liquid media, were evaluated against gram-positive (Bacillus subtilis and Staphylococcus aureus) and gram-negative (Escherichia coli) bacteria by the disk diffusion method. All of the mushrooms, except Auriporia aurea, Fomes fomentarius, and Lyophyllum shimeji, showed different antibacterial activity levels—from 9.5 mm in diameter of the inhibition zone to full inhibition of growth of the test bacteria. The antibacterial activities of Crinipellis schevczenkovi, Hohenbuehelia myxotricha, Oxyporus obducens, and Spongipellis litschaueri were observed for the first time. The antibacterial potential of culture liquids of the investigated species was higher than that of their mycelia activity. Dependence of the intensity of antibacterial activity on the culture medium was shown. The antibacterial efficiency of the most active species (Lentinus edodes, Piptoporus betulinus, and Phellinus igniarius) was verified and compared with those of some commercial antibiotics and natural essential oils of Salvia and Eucalyptus. The culture liquid of Piptoporus betulinus, obtained after cultivation on glucose-peptone-yeast culture medium, is a potential substance for further creation of antibacterial products.

Ivanova, Tetiana S.,Bisko, Nina A.,Krupodorova, Tetiana A.,Barshteyn, Victor Yu. The Korean Society for Microbiology and Biotechnol 2014 한국미생물·생명공학회지 Vol.42 No.1
A new substrate, breadcrumbs, was investigated for biomass accumulation, the pH of the cultural broth, the formation of primary metabolites such as the proteins and endopolysaccharides of Schizophyllum commune 1768 and Trametes versicolor 353, as well as its bioconversion efficiency. The results showed that S. commune gives more mycelial mass ($23.96{\pm}0.8g/l$) and in a shorter period (4 days) than T. versicolor ($15.76{\pm}0.5g/l$ in 5 days). The pH values changed from the initial 6.1 to 3.6 in S. commune cultural broth and to 4.4 in T. versicolor cultural broth. Maximal endopolysaccharide content in the mycelia of S. commune and T. versicolor were 7.13% and 6.42%, correspondingly. Crude protein content in S. commune mycelium was 18.83 % on the 4th day of cultivation, and 20.03%, in the mycelium of T. versicolor, on the 6th day of cultivation. Kinetic parameters for the quantitative estimation of cultivation efficiency were calculated for biomass, endopolysaccharide, and crude protein concentrations.
