Abstract：
As the most abundant and renewable natural resource in the world, lignocellulose is a promising alternative to fossil energy to relieve environmental concerns and resource depletion. However, due to its recalcitrant structure, strains with efficient degradation capability still need exploring. In this study, a fungus was successfully isolated from decayed wood and named as Trichoderma asperellum LYS1 by phylogenetic and draft genomic analysis. The further investigations showed that strain LYS1 had an outstanding performance on lignocellulose degradation, especially for hemicellulose-rich biomass. After the analysis of encoded CAZymes, mainly on GH family, a large amount of genes coding β-glucosidase and xylanase may contribute to the high degradation of cellulose and hemicellulose. Collectively, the results generated in this study demonstrated that T. asperellum LYS1 is a potential cell factory for lignocellulose biorefinery.
摘要：
作为世界上最丰富和可再生的自然资源，木质纤维素是一种有前途的替代化石能源，以缓解环境问题和资源枯竭。然而,由于其顽固的结构，具有高效降解能力的菌株仍需探索。在这项研究中,通过系统发育和基因组草图分析，成功地从腐烂的木材中分离出一种真菌，并将其命名为木霉菌LYS1。进一步的研究表明，菌株LYS1具有优异的降解木质纤维素的性能，特别是对于富含半纤维素的生物质。在对编码的CAZymes进行分析之后，主要是GH家族，大量编码β-葡萄糖苷酶和木聚糖酶的基因可能有助于纤维素和半纤维素的高度降解。总的来说，在这项研究中产生的结果表明，天蚕LYS1是木质纤维素生物精炼的潜在细胞工厂。
