摘要: 拜赖青霉Penicillium bilaiae菌株47M-1对多种芝麻病原真菌具有显著的抑制作用,为了分析该菌株产生的抑菌活性物质,本研究使用液相色谱串联质谱(LC-MS/MS)技术,检测菌株47M-1培养48、96和144 h时的代谢物,并分析上调差异代谢物在HMDB数据库的分类情况和KEGG代谢通路富集情况,进一步锁定潜在的活性代谢物,进行聚类分析,并验证部分上调代谢物的抑菌活性。经代谢组学数据分析,筛选出105种上调差异代谢物,上调差异代谢物在苯丙素和聚酮类化合物超类中富集最多。KEGG代谢通路富集分析结果表明,上调差异代谢物主要富集在代谢途径、辅因子生物合成、嘌呤代谢、氨基酸生物合成和ABC转运体等通路。通过含药平板法对部分上调差异代谢物的抑菌活性进行验证,其中柚皮素、原儿茶酸、D-(-)-奎宁酸、橙皮素、3-(3-羟基苯基)丙酸、3, 4-二羟苯基丙酸、4’, 5, 7-三羟黄烷酮、迷迭香酸、佛手苷内酯和圣草酚,对芝麻病原真菌具有良好的抑菌活性。本研究明确了菌株47M-1产生的潜在抑菌活性代谢物的主要类群和关键代谢通路,并验证了部分上调差异代谢物的抑菌活性,为菌株47M-1的进一步开发利用及微生物源农药的研发提供了理论支持。

Abstract: Strain 47M-1 of Penicillium bilaiae showed significant inhibitory effect on a variety of sesame pathogenic fungi. In order to analyze the inhibitiory active substances produced by this strain, liquid chromatography tandem mass spectrometry was used to detect the metabolites of strain cultured for 48 h, 96 h and 144 h. Then, classification of up-regulated differential metabolites in the HMDB database and enrichment of KEGG metabolic pathways were analyzed in order to identify the active metabolites. A total of 105 up-regulated differential metabolites were detected, which were mainly enriched in the superclasses of phenylpropanoids and polyketides. The enrichment analysis of the KEGG metabolic pathways showed that the up-regulated differential metabolites were mainly enriched in metabolic pathways, biosynthesis of cofactors, purine metabolism, biosynthesis of amino acids and ABC transporters. The inhibitiory activities of some up-regulated differential metabolites were verified using medicated plate method. These compounds naringenin, protocatechuic acid, D-(-)-quinic acid, hesperetin, 3-(3-Hydroxyphenyl) propanoic acid, 3, 4-dihydroxyhydrocinnamic acid, 5, 7-dihydroxy-2-(4-hydroxyphenyl)-3, 4-dihydro-2H-1-benzopyran-4-one, rosmarinic acid, bergapten and eriodictyol all showed excellent inhibition activities against sesame pathogenic fungi. In this study, the major groups and key metabolic pathways of potential inhibition metabolites produced by strain 47M-1 were identified, and the inhibitiory activity of some up-regulated differential metabolites was verified. This study will provide data support for the further development and utilization of strain 47M-1 and the research and development of microbial pesticide.
