摘    要:目的:筛选、鉴定自然发酵的安化茯砖茶中的金花菌,优化分离菌株在安化黑毛茶为原料的发酵条件,实现人工发酵制备安化茯砖茶。方法 以安化白沙溪茯砖茶为实验材料,经过分离、纯化、培养,观察分离菌株的培养特征。对分离菌株进行DNA提取和PCR扩增、测序,以及分子生物学系统发育分析。将分离菌株人工培养后,以菌丝体干重量为考察指标,黑毛茶冲泡液为原始发酵液,对分离菌株的实验室的发酵条件进行优化。结果 分离的单菌落经过比对鉴定为曲霉属(Aspergillus),推测为谢瓦曲霉(Aspergillus chevalieri)。实验室人工发酵条件确定为:发酵温度28 ℃,转速120 r/min,最佳碳源葡萄糖为90 g/L、氮源NH4Cl为7.5 g/L、无机盐CaCl2为5 g/L,装液量150 mL, 接种量为2.0 mL,发酵时间为6 d。优化后培养基中菌丝体干重量约为空白培养基组的20倍。结论 优化发酵培养条件后制得的发酵剂,可用于人工接种发酵安化黑毛茶,制备安化茯砖茶。

关 键 词:安化黑毛茶  安化茯砖茶  谢瓦曲霉  筛选  系统发育树
