Analysis of a thermophilic lignocellulose degrading microbial consortium and multi-species lignocellulolytic enzyme system

Distribution of typical denitrifying functional genes and diversity of the <i>nirS</i>-encoding bacterial community related to environmental characteristics of river sediments

“…Cluster-A dominated in all clone libraries with 57 %, 80 %, 52 %, 63 %, 61 %, and 65 % in the layers of ZB5, ZB10, ZB15, H5, H10, and H15, respectively. This cluster belonged to the family Rhodocyclaceaewhich contained mainly aerobic and denitrifying rodshaped bacteria with very versatile metabolic capabilities (Martins et al, 2010;Wongwilaiwalin et al, 2010). One OTU was closely related to the family Comamonadaceae.…”

Characteristics of a microbial consortium with high lignocelluloses-decomposing capacity

“…The residual substrates were then determined gravimetrically after drying at 105 ºC for 72 d with uninoculated medium as a control. %Residual weight was reported based on total holocellulose content [1]. The reactions were performed in triplicate and the averages of the results were reported.…”

“…Lignocellulosic wastes are the most abundant and environment-friendly material generated annually because of forestry, agricultural and industrial activities [1]. With the depletion of non-renewable energy, as the most attractive and promising avenue for cost-efficient treatment, bioconversion of large amounts of lignocellulosic biomass into fermentable material has been considered to be potential application in the area of bioenergy generation [2].…”

Degradation of Lignocellulosic Components in Un-pretreated Vinegar Residue Using an Artificially Constructed Fungal Consortium

“…Compared with traditional pure culture fermentations, mixed culture fermentations can allow the use of cheap and impure wastes, overcome the limitation of nutrition, achieve higher product yield and growth rate, and strengthen the protection of the culture from contamination (Yang et al 2004;Lin et al 2011). Although traditional fungal consortia obtained directly from nature usually have strong lignocellulose degradation abilities, their capabilities are easy to degenerate because of their unknown and complicated composition, adversely affecting the potential for practical application (Kato et al 2005;Wongwilaiwalin et al 2010). Since more and more fungi capable of lignocellulose degradation have been isolated and purified, there are increased opportunities for artificial construction of fungal consortia to improve the degradation efficiency.…”

“…Fungi are efficient degraders because of their extracellular enzymatic system, hyphal penetration power, and the ability to produce an enormous number of spores, which can invade substrates quickly (Kausar et al 2010;Sharma and Arora 2013). Because no single strain could produce all the enzymes necessary for lignocellulose degradation, current research is focused on fungal consortia with advantages of avoiding feedback regulation and metabolite repression (Wongwilaiwalin et al 2010). Compared with traditional pure culture fermentations, mixed culture fermentations can allow the use of cheap and impure wastes, overcome the limitation of nutrition, achieve higher product yield and growth rate, and strengthen the protection of the culture from contamination (Yang et al 2004;Lin et al 2011).…”
