Functional Enzyme Analysis and Metabolic Regulation Mechanism of The Combined Microflora Lxb in the Degradation of Lignocellulose

Опубликована: Янв. 1, 2023

The biodegradation of lignocellulosic biomass is a practical and effective method. A random combination six isolates two purchased strains was constructed to obtain LXB, the degradation lignocellulose resulted in 40.6% after 168 hours. total 1872 genes that were differentially expressed involved LXB have been identified Carbohydrate-Active enZYmes Database. Genes encode cellulases hemicellulase abundance, gene encodes displaying highest expression at initial peak stages degradation. Considerable increase Versatile peroxidase coenzyme Alcohol oxidase lignin catabolism. catalyzes breakdown mainly through pathways carbohydrate metabolic pathway, catechol discovered benzoate which participates lignin. Additionally, possesses capability degrade harmful exogenous substances.

A novel process of alkali-heat pretreatment - mixed culture fermentation was proposed to produce butyric acid from rice straw, but generating waste (PW) and (FW). In this study, the feasibility methane wastes confirmed, with production PW FW 351.1 ± 11.8 741.5 14.2 mLCH₄/gVS, respectively. The initial pH V_FW/V_PW using were optimized at 7.5 1.8, also verified by operating two anaerobic digesters in sequencing batch mode. At 0.25 (actual ratio), 301.20 mLCH₄/gVS load 0.64 kgVS/m³/d. When 1.8 (optimal reached 396.45 1.20 kgVS/m³/d. This study facilitates comprehensive utilization all components within straw.
