Abstract: The polysaccharides from Ganoderma lucidum by boiling water method was extracted. These crude extracts were tested for antimicrobial activitiy to three kinds of plant pathogens (Erwinia carotovora, Penicillium digitatum, Botrytis cinerea) and five kinds of food farmful bacteria(Bacillus cereus, Bacillus subtilis, Escherichiacoli, Aspergillus niger and Rhizopus nigricans) with the agar diffusion method. The results showed that the polysaccharides liquid had a powerful inhibiting effect on Erwinia carotovora, a weak inhibiting effect on Penicillium digitatum and nearly non- in?? hibiting effect on Botrytis cinerea for the plant pathogens. For the food harmful bacteria, the polysaccharides liquid had a strong inhibiting effect on Bacillus subtilis and Bacillus cereus, a weak inhibiting effect on Escherichia coli and As pergillus niger, nearly non??inhibiting effect on Rhizopus nigricans. In a word, the antimicrobial activity of polysaccha?? rides from Ganoderma lucidum was higher on bacteria than that of on fungi.

Key words: Ganoderma lucidum polysaccharides, Antimicrobial activity, Inhibiting effect
