摘　　要：比较了8个灵芝菌株的菌丝生长速度、菌丝体生物量及多糖含量等指标。试验结果表明,在PDA培养基上,沂山灵芝菌株菌丝生长速度最快,为9.91 mm/d;经150 r/min、25℃液体摇床培养10 d后,安丘大灵芝菌株获得的菌丝体生物量最高,为1.22 g/100 mL;济宁圆芝菌丝体中的多糖含量最高,为117.59μg/mg。经过综合分析比较,初步认为沂山灵芝为优势菌株。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 ram/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 （150r/min）, submerged cultures incubated at 25℃. Mycelium of a third G. lucidum strain （strain 818） had the highest polysaceharide content （117.59μg/mg）. Overall, when all three test parameters were considered together, strain 919 was pre-eminent.
