Abstract

Carbon, hydrogen and nitrogen analyses of banana leaf and pseudostem biomass revealed their potentiality as substrates for microorganisms. Infra-red (IR) spectra of both biomass show presence of cellulose, xylan and lignin. IR spectra of leaf and pseudostem biomass degraded in solid state fermentation (SSF) by two Pleurotus species (P. sajor-caju and P. ostreatus) for 40 days showed the utilization of cellulose, xylan and lignin by these microbes. Dynamics of various lignocellulolytic enzymes of Pleurotus species and analyses of carbon, hydrogen and nitrogen contents of degraded biomass supported the same. Both the Pleurotus species exhibited lignin consumption ability on both the substrates.

摘要

对香蕉叶和假茎生物质进行的碳、氢和氮分析表明，它们有潜力作为微生物的底物。两种生物质的红外（IR）光谱显示存在纤维素、木聚糖和木质素。两种侧耳属真菌（糙皮侧耳和佛罗里达侧耳）在固态发酵（SSF）中对叶片和假茎生物质进行40天降解后的IR光谱表明，这些微生物利用了纤维素、木聚糖和木质素。侧耳属真菌各种木质纤维素酶的动态变化以及对降解后生物质的碳、氢和氮含量分析也证实了这一点。两种侧耳属真菌在这两种底物上均表现出木质素消耗能力。
