“…The samples were investigated using an isocratic elution 0.2% H3PO4 at 1 mL min -1 and column temperature of 50 °C. The wavelength was 210 nm (Yu et al, 2016). The V-score is an important index for comprehensively evaluate ensilage fermentation quality, which was calculated to evaluate the fermentative quality based on the values of organic acids and NH3-N content.…”

“…The archaeal 16S region was amplified using primers: 524F10extF: 5 -TGYCAGCCGCCGCGGTAA-3 and Arch958RmodR: 5 -YCCGGCGTTGAVTCCAATT-3 . PCR amplification of bacterial 16S rRNA was conducted by sequencing the V3-V4 hypervariable region using the primers 338F: 5 -ACTCCTACGGGAGGCAGCA-3 and 806R: 5 -GGACTACHVGGGTWTCTAAT-3 [22]. The detailed operation is referred to in a previous report [23].…”

Lignin-feeding insect gut is a natural ligninolytic microbial bank for the sustainable conversion of crop straw to biogas. However, limited studies have been done on highly efficient microbes. Here, an efficient ligninolytic strain Enterobacter hormaechei KA3 was isolated from the gut microbiomes of lignin-feeding Hypomeces squamosus Fabricius, and its effects on lignin degradation and anaerobic digestion were investigated. No research has been reported. Results showed that strain KA3 had better lignin-degrading ability for corn straw with a higher lignin-degrading rate (32.05%) and lignin peroxidase activity (585.2 U/L). Furthermore, the highest cumulative biogas yield (59.19 L/kg-VS) and methane yield (14.76 L/kg-VS) were obtained for KA3 inoculation, which increased by 20% and 31%, respectively, compared to CK. Higher removal rates of COD, TS, and vs. of 41.6%, 43.11%, and 66.59% were also found. Moreover, microbial community diversity increased as digestion time prolonged in TG, and bacteria were more diverse than archaea. The dominant genus taxon, for methanogens, was Methanosate in TG, while in CK was Methanosarcina. For bacteria, dominant taxa were similar for all groups, which were Solibacillus and Clostridium. Therefore, strain KA3 improved the methane conversion of the substrate. This study could provide a new microbial resource and practical application base for lignin degradation.

“…From 65 to 95% methane is directly produced from acetic acid. The remaining major component, propionic acid remains unconverted as the degradation is thermodynamically less favourable compared to butyrate (Yu et al, 2016b). The final stage of methanogenesis mainly includes the function from acetotrophic and hydrogenotrophic methanogens.…”

The anaerobic digestion process has been primarily utilized for methane containing biogas production over the past few years. However, the digestion process could also be optimized for producing volatile fatty acids (VFAs) and biohydrogen. This is the first review article that combines the optimization approaches for all three possible products from the anaerobic digestion. In this review study, the types and configurations of the bioreactor are discussed for each type of product. This is followed by a review on optimization of common process parameters (e.g. temperature, pH, retention time and organic loading rate) separately for the production of VFA, biohydrogen and methane. This review also includes additional parameters, treatment methods or special additives that wield a significant and positive effect on production rate and these products' yield.
