BIOACTIVITY AND PHYTOCHEMICAL ANALYSIS OF THE MUSHROOM Rigidoporus lignosus (Klot) IMAZEKI

The antagonistic effect of hot and cold water extracts Rigidoporus lignosus was investigated in-vitro against some pathogenic microorganisms: Staphylococcus aureus , Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae Candida albicans. showed a wide spectrum antimicrobial activity. minimum inhibitory concentration (MIC) the were 16g/150ml 20g/150ml respectively. For albicans, MIC 14g/150ml respectively.The E. coli for both extracts.The did not inhibit aeruginosa pneumoniae. bactericidal (MBC) extract 20g/150ml. an MBC greater than this organism. E >20g/150ml.With extract, C. albicans but >20g/150ml using extract.The lowest zone inhibition 6.00± 00mm at 6hours either or water. This organism had widest 12.67± 0.33mm 24 hours next with diameter 12.36±0.09mm 72hours extract. significantly different (P=0.05) from that S.aureus (12.33±0.33mm) 16g/150ml. Phytochemical analysis it to contain flavonoids, saponins alkaloids which are probably responsible its biological Both mushroom will be helpful in managing bacterial fungal infections employed as food preservative.
