The hydrolysis and biotransformation of lignocellulose, i.e., biorefinery, can provide human beings with biofuels, bio-based chemicals, materials, is an important technology to solve the fossil energy crisis promote global sustainable development. Biorefinery involves steps such as pretreatment, saccharification, fermentation, researchers have developed a variety biorefinery strategies optimize process reduce costs in recent years. Lignocellulosic hydrolysates are platforms that connect saccharification downstream fermentation. hydrolysate composition closely related biomass raw pretreatment process, choice biorefining strategies, provides not only nutrients but also possible inhibitors for In this review, we summarized effects each stage lignocellulosic on inhibitors, analyzed huge differences nutrient retention inhibitor generation among various emphasized all lignocellulose need be considered comprehensively achieve maximum optimal control at low cost, reference development chemicals.

Synthetic microbial community (SynCom) application is efficient in promoting crop yield and soil health. However, few studies have been conducted to enhance pepper growth via modulating rhizosphere communities by SynCom application. This study aimed investigate how inoculation at the seedling stage impacts microbiome using high-throughput sequencing technology. significantly increased shoot height, stem diameter, fresh weight, dry chlorophyll content, leaf number, root vigor, tips, total length, root-specific surface area of 20.9%, 36.33%, 68.84%, 64.34%, 29.65%, 27.78%, 117.42%, 35.4%, 21.52%, 39.76%, respectively, relative control. The Chao index Bray–Curtis dissimilarity fungal increased, while bacterial decreased inoculation. abundances key taxa such as Scedosporium, Sordariomycetes, Pseudarthrobacter, norankSBR1031, norankA4b with inoculation, positively correlated indices growth. Our findings suggest that can effectively regulate morphology regulating increasing abundance like Sordariomycetes thereby benefiting nutrient acquisition, resistance improvement, pathogen crops ensure sustainability.
