Lytic polysaccharide monooxygenases utilise reducing agents within the biomass substrate to act synergistically with canonical hydrolases enhance cellulose deconstruction.
Currently, the amount of protein/enzyme required to achieve effective cellulose hydrolysis is still too high. One way reduce formulate a more efficient enzyme cocktail by adding so-called accessory enzymes such as xylanase, lytic polysaccharide monooxygenase (AA9, formerly known GH61), etc., cellulase mixture. Previous work has shown strong synergism that can occur between and xylanase mixtures during steam pretreated corn stover, requiring lower protein loading hydrolysis. However,...
Significance Some of the most damaging tree diseases are caused by pathogens that induce cankers, a stem deformation often lethal. To investigate cause this adaptation, we sequenced genomes poplar do and not cankers. We found unique cluster genes produce secondary metabolites co-activated when canker pathogen is grown on wood leaves. The gene genealogy discordant with species phylogeny, showing signature horizontal transfer from fungi associated decay. Furthermore, encoding...
Abstract Effective enzymatic hydrolysis of insoluble cellulose requires the synergistic action a suite cellulase components. Most previous studies have only assessed synergism on model cellulosic substrates. When actions individual and combinations cellulases (Cel7A, Cel6A, Cel7B, Cel5A) were various pretreated lignocellulosic substrates, Cel7A was shown to be major contributor overall hydrolysis, with other enzymes synergistically enhancing its hydrolytic efficiency, at least partially, by...
The addition of Lytic polysaccharide monooxygenase (LPMO's) increases the desorption exoglucanases during hydrolysis cellulosic substrates.
Oil palm residues are not currently suitable as feedstock for thermal energy generation because their high ash content can cause slagging, corrosion, and fouling. A water leaching treatment is a potential strategy to reduce the in these residues. This study evaluates effects of duration temperature on two types oil residues, namely, empty fruit bunches (EFBs) kernel shells (PKSs). The optimum process removal from EFBs was found be 5 min, effect convection scrubbing observed remove...
It is widely recognised that fast, effective hydrolysis of pretreated lignocellulosic substrates requires the synergistic action multiple types hydrolytic and some non-hydrolytic proteins. However, due to complexity enzyme mixture, enzymes interaction with interference from substrate a lack specific methods follow distribution individual during hydrolysis, most enzyme-substrate studies have used purified pure cellulose model substrates. As present in typical "cellulase mixture" need work...
Abstract The Peranakan Chinese are culturally unique descendants of immigrants from China who settled in the Malay Archipelago ∼300–500 years ago. Today, among large communities Southeast Asia, Peranakans have preserved traditions with strong influence local indigenous Malays. Yet, whether or to what extent genetic admixture co-occurred cultural mixture has been a topic ongoing debate. We performed whole-genome sequencing (WGS) on 177 Singapore (SG) and analyzed data jointly WGS Asian...
The forests of British Columbia have been managed for thousands years to provide a range products and services. For the Nuxalk people Bella Coola, BC, their were used build homes canoes, act as transportation system (grease trails), material clothing, fuel cultural/artistic needs. These also host plants nourishment medicine. lives First Nations dramatically altered with arrival Western cultures; from perspective, these traditional goods services eroded. Today they seek restore protect that...
Relatively high enzyme loadings are required for the bioconversion of lignocellulosic biomass, impeding economical production cellulosic sugars. The relative stability and robustness these enzymes make recycling an attractive cost-reduction strategy. However, efficiency has been limited by complexity enzyme-substrate interactions, which influenced enzyme, substrate, physical factors. A lack techniques to probe specific adsorption further limits our understanding interactions. Therefore,...
The large quantities of waste sludge produced by the pulp and paper industry present significant environmental challenges. In order to minimize amounts waste, should be utilized for productive applications. find feasible solutions, need characterized. this study, potential using acid pretreatment ashing method determine chemical compositions is investigated. This study shows that could used dissolve composition CaCO3 in sludge. removal also facilitates measurement fiber ash (clay) contents...
