摘　　要：针对发酵生产灵芝酸产量低的现状,在灵芝液体静置培养基中添加不同浓度油茶籽壳提取液,探究其对灵芝生长和灵芝酸合成的影响。结果表明:低浓度油茶籽壳提取液能促进灵芝细胞生长,高浓度会抑制生长。高浓度油茶籽壳提取液有利于灵芝酸的积累,添加50%和100%油茶籽壳提取液总灵芝酸含量达到了6.64和7.97 mg·dg^(-1),分别提高了67%和101%,总灵芝酸产量达到了1406.37和1599.73 mg·L^(-1),分别为对照组的1.34和1.52倍。GA-Mk、GA-T、GA-S和GA-Me 4种灵芝酸单体也均有不同程度提高。可见油茶籽壳提取液可用于促进灵芝酸生产。In view of the low yield of ganoderic acid produced by fermentation,different concentrations of camellia seed shell extract were added to the liquid static culture medium of Ganoderma lucidum to explore their effect on the growth of Ganoderma lucidum and the synthesis of ganoderic acid.The results showed that the low concentration of camellia seed shell extract could promote the cell growth of Ganoderma lucidum,while the high concentration would inhibit the growth.The high concentration of camellia seed shell extract was beneficial to the accumulation of ganoderic acid.The total content of ganoderic acid when added with 50%and 100%camellia seed shell extract could reach 6.64 and 7.97 mg·dg^(-1),which was increased by 67%and 101%,respectively.The total yield of ganoderic acid reached 1406.37 and 1599.73 mg·dg^(-1),which were 1.34 and 1.52 times of the control group,respectively.And the four kinds of ganoderic acid monomers,such as GA-Mk,GA-T,GA-S and GA-Me were also increased to varying degrees.It could be seen that the extract of camellia seed shell could be used to promote the production of ganoderic acid.
