Abstract

Abstract : Pretreatment of lignocellulosic biomass by using synergistic microbial consortium is an efficient way to promote biomass utilization efficiency. Abstract : Lignocelluloses featuring complicated structure and poor degradability usually require pretreatments prior to their utilization; synergistic microbial systems are ubiquitous in nature and now exhibit appealing features that inspire mounting interest in developing functional microbial consortia for biotechnology development. In this study, we introduced a microbial consortium composed of bacteria and fungi that synergistically exhibited great abilities of lignocellulose degradation. A pretreatment of lignocelluloses by using this functional microbial consortium was designed and results showed that enhanced degradability in wheat straw and the broth containing amounts of organic materials ( e.g. volatile fatty acids and carbohydrates) that could be used for biogas synthesis were detected in the pretreatment system. A subsequent anaerobic fermentation with the application of the pretreated system showed a 39.24% and 80.34% increase in total biogas and methane yield as well as a faster startup in a 20 day production process compared to the process based on the untreated system.
