Supercritical methanolysis (SCM) of pretreated wheat straw (WS) with the white-rot fungus Trichoderma sp. AH was investigated. Structural change of pretreated WS was examined by Fourier transform infrared spectrometric analysis and chemical analysis as well as observation with a scanning electron microscope. The optimal pretreatment (PT) time of WS was 5 days of incubation, obtaining the maximum methanol-soluble portion (MSP) yield of 38.3% at 260 °C, compared with MSP yield of 24.6% of raw WS. According to the detailed compositional analysis of MSPs from SCM of raw and pretreated WS, after 5 days of incubation, PT with Trichoderma sp. AH enhanced conversion, specificity and content of esters significantly. Especially, the relative contents of methyl palmitate, methyl (9Z,12Z)-octadeca-9,12-dienoate, and methyl (E)-octadec-11-enoate in MSPs were increased dramatically. Therefore, the study brings out the potential of PT with Trichoderma sp. AH for facilitating conversion and specificity of biomass in liquefaction.

预处理的麦秸（WS）与白腐真菌Trichoderma sp。的超临界甲醇分解（SCM）。对AH进行了调查。通过傅里叶变换红外光谱分析和化学分析以及用扫描电子显微镜观察来检查预处理的WS的结构变化。WS的最佳预处理（PT）时间是孵育5天，在260°C下获得38.3％的最大甲醇可溶部分（MSP）产率，而原始WS的MSP产率为24.6％。根据来自原始和预处理WS的SCM的MSP的详细组成分析，孵育5天后，用木霉属菌种PT 。AH显着提高了酯的转化率，特异性和含量。尤其是棕榈酸甲酯（9 ZMSPs中的，12 Z）-octadeca-9,12-二烯酸和甲基（E）-octadec-11-enoate显着增加。因此，这项研究揭示了木霉属木霉菌对PT的潜力。AH，用于促进液化中生物质的转化和特异性。
