The optimal temperature and pH was 30-35 C and 4-4 5 respectively in a glucose-ammonium chloride medium and polysaccharide concentration reached l 6mg ml. Agitation and aeration influenced the formation and secretion of polysaccharide. The optimal rotating speed was 150 rpm in 7-day flask cultures while the agitation speed employed in fermenter culture greatly affected the production rate and maximum concentration of polysaccharide. Although higher speeds enhanced mixing efficiency and polysaccharide release higher shear stress had a detrimental effect on mycelial growth and polysaccharide formation. 1998 Elsevier Science Ltd. All rights reserved Keywords Ganoderma lucidum polysaccharide submerged culture. Introduction Ganoderma lucidum Fr. Krast Polyporaceae and related species are fungi used in traditional Chinese medicine. Its fruiting body is called Reishi or Man-nentakc in Japanese and Lingzhi in China. In regions of China Japan Korea and Taiwan Lingzhi has been a popular folk or oriental medicine used to treat various human diseases such as hepatitis hypertension hypercholesterolemia and gastric cancer. Recent studies on this fungus have demonstrated many interesting biological activities including antitumour and anti-inflammatory effects and cytotoxicity to hepatoma cells. These studies also suggested that the .
