Abstract: The antimicrobial activities of Russula vinosa Lindbl mycelium and its submerged culcure fermentation broth were determined by primary-explant and filter paper disk test methods. The results indicated that the mycelium of Russula vinosa Lindbl has the strongest antimictrobial effect against bacteria, but weak inhibiting effect on yeast and mould. The results also showed that the antimicrobial activities of the submerged culture fermentation broth of Russula vinosa Lindbl against Escherichia coli and Staphylococcus aureus are the strongest, but the activities angainst Aspergillus niger and Aspergillus oryzae are weak. The antimicrobial activity of the submerged 4-day culture fermentation broth of Russula vinosa Lindbl, is up to maximum.

Key words: Russula vinosa Lindbl, mycelium, submerged cultivation fermentation broth, antimicrobial activitiy
