竹黄无性型菌株产竹红菌素的研究

目的获得能稳定产生竹红菌素的竹黄无性型菌株,通过人工培育获得其活性成分竹红菌甲素。方法通过组织分离,从野生竹黄子座中分离筛选出无性型菌株0258,进行人工条件下的发酵培养。对其发酵产物进行提取、分离和纯化,通过理化性质测定和波谱(UV/V IS、IR、M S)技术进行结构鉴定。结果从竹黄子实体分离筛选到一株无性型菌株0258,其能产生稳定的竹红菌甲素。结论首次获得稳定产生竹红菌素的竹黄无性型菌株,解决了竹黄人工培育的种源问题,使竹红菌素的工业化生产成为可能。

Hypocrellins produced by anamorphosis fermentation of Shiraia bambusicola

Objective To obtain anamorphosis of Shiraia bambusicola producing the component,hypocrellin A effectively.Methods A strain was isolated from the fruit of S.bambusicola by separating its hypha and was cultured by solid-state fermentation.One of the pure chemical compounds isolated from the stroma of wild S.bambusicola was studied on the basis of UV/VIS,IR,MS spectrometric analysis and physicochemical constants.Results The pigment is proved to be hypocrellin A.The isolate was determined as the stable anamorphosis strain 0258 of S.bambusicola.Conclusion A namorphosis strain of S.bambusicola is obtained and precisely appraised for the first time.This study will provide basis for the future massively industrialized hypocrellin production.
