Abstract

157 was isolated from the bark of , and exhibited antagonistic activity against a broad spectrum of pathogenic bacteria and fungi. Moreover, 157 also showed various lignocellulolytic activities including cellulase, xylanase, α-amylase, and pectinase, which had the ability of using the agro-industrial waste (soybean meal, wheat bran, sugarcane bagasse, wheat straw, rice husk, maize flour and maize straw) under solid-state fermentation and obtained several industrially valuable enzymes. Soybean meal appeared to be the most efficient substrate for the single fermentation of 157. Highest yield of pectinase (19.15 ± 2.66 U g), cellulase (46.69 ± 1.19 U g) and amylase (2097.18 ± 15.28 U g) was achieved on untreated soybean meal. Highest yield of xylanase (22.35 ± 2.24 U g) was obtained on untreated wheat bran. Here, we report the complete genome sequence of the 157, composed of a circular 4,013,317 bp chromosome with 3789 coding genes and a G + C content of 46.41%, one circular 8439 bp plasmid and a G + C content of 40.32%. The genome contained a total of 8 candidate gene clusters (bacillaene, difficidin, macrolactin, butirosin, bacillibactin, bacilysin, fengycin and surfactin), and dedicates over 15.8% of the whole genome to synthesize secondary metabolite biosynthesis. In addition, the genes encoding enzymes involved in degradation of cellulose, xylan, lignin, starch, mannan, galactoside and arabinan were found in the 157 genome. Thus, the study of 157 broadened that can not only be used as biocontrol agents, but also has potentially a wide range of applications in lignocellulosic biomass conversion.

摘要

157是从[植物名称]的树皮中分离得到的,对多种病原菌和真菌具有拮抗活性。此外,157还表现出多种木质纤维素分解活性,包括纤维素酶、木聚糖酶、α-淀粉酶和果胶酶,其能够在固态发酵条件下利用农业工业废弃物(豆粕、麦麸、甘蔗渣、小麦秸秆、稻壳、玉米粉和玉米秸秆)并获得多种具有工业价值的酶。豆粕似乎是157单一发酵最有效的底物。在未处理的豆粕上,果胶酶(19.15±2.66 U/g)、纤维素酶(46.69±1.19 U/g)和淀粉酶(2097.18±15.28 U/g)的产量最高。在未处理的麦麸上,木聚糖酶产量最高(22.35±2.24 U/g)。在此,我们报道了157的完整基因组序列,其由一个4,013,317 bp的环状染色体组成,有3789个编码基因,G+C含量为46.41%,一个8439 bp的环状质粒,G+C含量为40.32%。该基因组共有8个候选基因簇(杆菌肽、艰难梭菌素、大环内酯、丁酰苷菌素、杆菌铁载体、芽孢溶素、丰原素和表面活性素),并将超过15.8%的全基因组用于合成次级代谢产物生物合成。此外,在157基因组中发现了编码参与纤维素、木聚糖、木质素、淀粉、甘露聚糖、半乳糖苷和阿拉伯聚糖降解的酶的基因。因此,对157的研究拓宽了[微生物名称]的应用范围,其不仅可以用作生物防治剂,还在木质纤维素生物质转化方面具有广泛的潜在应用。
