马尾松（pinusmassoniana）内生真菌的产油脂效果
DOI: 10.3724/SP.J.1145.2014.10030, PP. 377-381
Keywords: 马尾松,内生真菌,微生物油脂,gc-ms
Abstract:
从马尾松根、茎、叶分离出21株内生真菌，应用酸热法提取4株优势菌株油脂，测定油脂含量，并采用气相色谱？质谱联用技术（gc-ms）分析油脂组分.结果表明：4株马尾松内生真菌均含有油脂，油脂含量均达20%以上，最高含量达30.13%.4株菌都含有脂肪酸，且均占油脂提取物的64%以上，不饱和脂肪酸含量均达46%以上.油脂组分主要为棕榈酸酯、硬脂酸、油酸、亚油酸、反油酸等，其中油酸含量最大，达42.08%.因此，马尾松内生真菌可作为一种新的微生物资源用于微生物油脂生产，具有很高的开发利用价值.
