野生药用真菌光核纤孔菌的生物学特性和抗氧化活性OA
Biological characteristics and antioxidant activities of the wild medicinal mushroom Inocutis levis
本研究选取广义桑黄类真菌光核纤孔菌Inocutis levis作为研究对象,针对光核纤孔菌在固体培养过程中的生物学特性指标及在液体发酵过程中分泌的多糖、多酚、黄酮、抗坏血酸、超氧化物歧化酶、清除自由基能力以及铁离子还原能力变化进行了测定,证实分离自新疆克拉玛依市小拐乡胡杨林上的野生光核纤孔菌以淀粉、酵母浸粉、KH2PO4、pH 9、35℃作为其最适碳源、氮源、无机盐、pH和温度,且具有显著的抗氧化活性(P<0.01),该研究为今后该种野生药用真菌资源的保护、开发和利用提供了资源储备和基础数据.
Cultivation of the wild Inocutis levis isolated from Populus euphratica in Xiaoguai Town in Karamay of Xinjiang was carried out.It was found that using starch and yeast extract as carbon and nitrogen sources,with the addition of KH2PO4 as inorganic salt,the fungus grew well under pH 9 and 35℃conditions.During liquid cultivation,polysaccharide,polyphenol,flavonoid,ascorbic acid,superoxide dismutase,scavenging abilities for free radicals,and ferric reducing antioxidant power of the fungus were determined.The results provide basic data for the protection,evaluation,development,and utilization of this wild medicinal fungus resources in the future.
