中文摘要: 为了秀珍菇的进一步开发利用，对秀珍菇进行了7L气升式发酵罐培养，并对其发酵液和菌丝体浸提液中的功能成分进行了分析。结果表明秀珍菇发酵至第6天时菌体干重达到16.53 g/L，发酵液和菌丝体浸提物中含有多糖、蛋白质、黄酮和多酚等功能成分。经检测，在发酵液中，多糖、蛋白质、黄酮和多酚的含量分别为0.672、0.052、0.126、0.122mg/mL；而菌丝体浸提液中，多糖、蛋白质、黄酮和多酚的含量分别为0.312、0.031、0.116、0.109 mg/mL。本研究表明，秀珍菇的液态发酵可获得较高含量的活性成分，为秀珍菇的进一步开发和利用提供了理论基础和技术支持。
Abstract:In order to further developPleurotus geesteranus，the present study was carried on the culture ofPleurotus geesteranusin 7L air-lift type fermentor，and the functional constituents in the fermentation broth and mycelium extract were analyzed.The results showed that the dry weight of mycelium reached 16.53 g/L at the 6th day，and the polysaccharide，protein，flavone and polyphenol were found in the fermentation broth and mycelium extract.The results showed that the contents of polysaccharides，proteins，flavones and polyphenols in the fermentation broth were 0.672，0.052，0.126，0.122 mg/mL，respectively.And the corresponding contents of the four functional components were 0.312，0.031，0.116，0.109 mg/mL in the mycelium extracts respectively.The results showed that the liquid fermentation ofPleurotus geesteranuscould obtain high content of active components，which provided the theoretical basis and technical support for the further development and utilization ofPleurotus geesteranus.
