BAI Dan,CHANG Nai-tao,LI Da-hai,LIU Ji-xia,YOU Xue-yan(Key Laboratory of North Crop Disease Immunity,Ministry of Agriculture,Shenyang Agricultural University,Shenyang 110161,China)  
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,Escherichia coli,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-inhibiting 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 Aspergillus niger,nearly non-inhibiting effect on Rhizopus nigricans.In a word,the antimicrobial activity of polysaccharides from Ganoderma lucidum was higher on bacteria than that of on fungi.
