Biological characteristics and antioxidant activities of both medicinal and edible Ischnoderma resinosum
摘要
Abstract
The polypore Ischnoderma resinosum is both medicinal and edible,having potential to be developed as health foods.The biological characteristics and antioxidant activities of a I.resinosum strain collected from Changbai Mts.,Jilin Province were studied.The ideal conditions for the mycelial growth of I.resinosum,including optimal carbon and nitrogen sources,inorganic salts,pH,and temperature,were systematically tested through single-factor and orthogonal experiments as well as Box-Behnken design under solid-state cultivation.Some indexes for its antioxidant activities were measured by spectrophotometry during liquid cultivation.Single-factor experiment results indicated that sucrose,malt extract,and KH2PO4 were the most favorable carbon source,nitrogen source,and inorganic salt,respectively,for the mycelial growth,particularly at pH 6.0 and temperature of 25 ℃.Further orthogonal test displayed that the impact extent on the mycelial growth rate were ranked as nitrogen source>carbon source>pH>inorganic salt.The levels of the main factors that affect the mycelial growth rate were authenticated by the Box-Behnken design.I.resinosum could produce substantial quantities of polysaccharides,polyphenols,and ascorbic acids as well as possessed superoxide dismutase activities and the abilities to scavenge hydroxyl radicals,as observation under liquid culture.The optimal medium for mycelial growth were sucrose 20.0 g/L,malt extract 13.0 g/L,and KH2PO4 0.7 g/L.Under pH 5.0 and 25 ℃,the mycelial growth rate was(12.07±0.11)mm/d.I.resinosum antioxidant activity was confirmed by determination of several indexes in the liquid cultivation.关键词
