【中文摘要】 比較了8個靈芝菌株的菌絲生長速度、菌絲體生物量及多糖含量等指標。試驗結果表明,在PDA培養(yǎng)基上,沂山靈芝菌株菌絲生長速度最快,為9.91 mm/d;經150 r/min、25℃液體搖床培養(yǎng)10 d后,安丘大靈芝菌株獲得的菌絲體生物量最高,為1.22 g/100 mL;濟寧圓芝菌絲體中的多糖含量最高,為117.59μg/mg。經過綜合分析比較,初步認為沂山靈芝為優(yōu)勢菌株。

【英文摘要】 Eight Ganoderma strains were evaluated in terms of mycelial growth rate on potato dextrose agar, biomass production in submerged culture,and mycelial polysaccharide content.Highest mycelial growth rates (9.91 mm/d) were recorded with a strain of G.lucidum (strain 919),whereas another strain of this fungus (strain 414) produced the most mycelial biomass (1.22 g/100 mL) after 10 d growth in shaken (150 r/min), submerged cultures incubated at 25℃.Mycelium of a third G.lucidum strain (strain 818) had the highest polysaccharide content (117.59μg/mg).Overall,when all three test parameters were considered together, strain 919 was pre-eminent.
