Biomethane recovery performance and microbial community dynamics of a high-biomass submerged AnMBR (HBSAnMBR) treating abattoir wastewater

Biochemical Engineering Journal, Год журнала: 2024, Номер 205, С. 109275 - 109275

Опубликована: Фев. 28, 2024

This study investigated the treatment and biomethane recovery performance of a high-biomass submerged anaerobic membrane bioreactor (HBSAnMBR) treating abattoir wastewater in six operational phases (Phases 1 – 6) at an organic loading rate (OLR) range 1.05 7 kg-COD/m3/d. The HBSAnMBR system demonstrated 75.5 ± 2.0% COD removal efficiency 98.8 0.71% during most sustainable phase OLR 4 Volatile fatty acids (VFAs) such as acetic, propanoic, isobutyric, valeric significantly correlated with production, while butyric isovaleric acid concentrations were unaffected. positively microbial community dynamics different phases. functional analysis microbiome indicated that Pseudomonas Anaerolineaceae played significant role hydrolysis fermentation complex matter, which led to production VFAs other intermediate products. Methanothrix observed utilize acetate for acetoclastic methanogenesis kg-COD/m3/d, producing highest biomethane. On contrary, was replaced by hydrogenotrophic Methanolinea Methanospirillum above leading decline production.

Mixed plantation forest litter improves microbial nitrogen transformation by increasing nitrogen metabolism related genes and key bacterial taxa in northern China

Land Degradation and Development, Год журнала: 2024, Номер 35(8), С. 2840 - 2856

Опубликована: Март 17, 2024

Abstract Nitrogen (N) metabolism is a key metabolic pathway of nutrient cycling in forest ecosystems. However, the mechanisms by which mixed plantation litter improves microbial N transformation are poorly understood. Thus, we investigated characteristics, metabolism‐related genes, and modules soil three types forests: coniferous (CP forest), broadleaf (BP forests (MCBP forest). Results indicated that total (TN), hydrolysable organic (THON), percentage values NH 4 + ‐N/TN NO 3 − BP MCBP were higher than those CP litter, was attributed to increase abundance fixation genes dissimilatory nitrate reduction genes. The increased bacterial number diversity, taxa. Bacterial 1 2 identified, consisting Acidobacteria, Actinobacteria, Chloroflexi, Nitrospirae, Proteobacteria, Gemmatimonadetes, while archaeal module 5 also module, comprising Thaumarchaeota Euryarchaeota. Nutrients limiting factor decomposition further influencing enzymes. Therefore, during northern China.

Effect of forest planting patterns on the formation of soil organic carbon during litter lignocellulose degradation from a microbial perspective

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Litter decomposition is an important source of soil organic carbon, and it plays a key role in maintaining the stability forest ecosystems. The microbial mechanism carbon (SOC) formation different urban planting patterns during litter lignocellulose degradation still unclear. genes, microbes, metabolites process SOC were determined by metagenomics metabolomics layers patterns, including three types broadleaf forests (BP forests), coniferous (CP two mixed (MCBP forests). results indicated that cellulose, hemicellulose, lignin concentrations from undecomposed layer to totally decomposed decreased 70.07, 86.83, 73.04% for CP litter; 74.30, 93.80, 77.55% BP 62.51, 48.58, 90.61% MCBP litter, respectively. was higher than 38.06 94.43% 0–10 cm 38.55 20.87% 10–20 layer, Additionally, gene abundances glycoside hydrolases (GHs) polysaccharide lyases (PLs) those forests. Amino acid metabolism, sugar TCA cAMP signaling metabolism mainly between forests, while cycle, pyruvate phenylalanine tyrosine decomposition. ammonia nitrogen hemicellulose factors driving nitrogen, lignocellulose-degrading genes For pH, formation. Our findings revealed had stronger performance SOC. This study provided theoretical basis flow transformation nutrients management patterns.
