Bacterial exopolysaccharides as emerging bioactive macromolecules: from fundamentals to applications

Navneet Kaur et al.

Summary: Microbial exopolysaccharides (EPS) are extracellular carbohydrate polymers that form capsules or slimy coatings around cells, and they play important roles in attachment, environmental adaptation, stress tolerance, and biofilm formation. EPS produced by gut commensals have diverse bio-activities and find commercial applications in pharmaceutical and food industries. Genetic and metabolic engineering strategies are used to increase EPS production. This review provides a comprehensive overview of bacterial EPS, including their classification, source, biosynthetic pathways, and functions in the microbial community, as well as their bioactivities, particularly in the gut. The review highlights the importance of microbial bioactive exopolysaccharides.

Combined biological effects of polystyrene microplastics and phenanthrene on Tubifex tubifex and microorganisms in wetland sediment

Jiahao Dong et al.

Summary: Microplastics and polycyclic aromatic hydrocarbons (PAHs) have negative effects on invertebrates and microbes in aquatic environments. The addition of different particle sizes of microplastics and typical PAHs exacerbated oxidative damage and affected the degradation of phenanthrene in Tubifex tubifex and sediment. These findings contribute to the risk assessment of PAHs and microplastics in aquatic environments.

Microbial metabolism regulation on the efficient degradation of aromatic compounds for biochemical treatment process of coal chemical wastewater in pilot scale

Xingshe Liu et al.

Summary: The study investigated the regulation effect and mechanism of microbial metabolism on the efficient degradation of aromatic compounds in the biochemical treatment process of coal chemical wastewater. The addition of dominant microbial strains that could degrade aromatic compounds significantly increased the removal efficiencies of COD, TOC, phenols, benzenes, N-CHs, and PAHs in the system. The microbial community abundance and diversity, microbial activity, and enzymatic activity were all improved, leading to enhanced performance for aromatic compounds removal and the formation of microbial hydrophobic cell surfaces.

Advantages of residual phenol in coal chemical wastewater as a co-metabolic substrate for naphthalene degradation by microbial electrolysis cell

Peng Ding et al.

Summary: The study found that high phenol concentrations in coal chemical wastewater can serve as an effective co-metabolic substrate for the degradation of naphthalene in microbial electrolysis cells. Phenol outperformed sodium acetate and glucose in facilitating naphthalene degradation efficiency. Additionally, phenol enhanced microbial biomass and exhibited optimal COD metabolism capacity. This study provides guidance for the effective co-degradation of naphthalene in coal chemical wastewater using phenol as a cosubstrate relative to simple substrates.

Effects of substrate type on variation of sludge organic compounds, bioelectric production and microbial community structure in bioelectrochemically-assisted sludge treatment wetland

Shutian Wang et al.

Summary: A study constructed four different bioelectrochemical assisted sludge treatment wetland (BE-STW) systems using different substrates to investigate their effects on organic compounds degradation, electricity production, and bacterial community. The results showed that the substrate materials significantly affected the output voltage, power density, and organic carbon removal rate of the systems. The degradation of aromatic compounds was mainly achieved by reducing the hydrophilic fraction and transphilic acid fraction. The substrates also influenced the removal of specific proteins and the fluorescent characteristics of humic acid-like substances. At the genus level, certain bacterial genera dominated the BE-STW systems, and different substrates introduced different bacterial genera.

Using a stable isotope tracing technique to elucidate the effect of substrate C/N ratio on the formation of different constituents of extracellular polymeric substances in an aerobic-anoxic sequencing batch reactor

Zeshan Arshad et al.

Summary: Carbon to nitrogen (C/N) ratios in wastewater affect the production and composition of extracellular polymeric substances (EPS) in biological treatment processes. This study used stable isotopes to examine the EPS yield and compositional changes in aerobic-anoxic sequencing batch reactors (SBR) with different C/N ratios. The results showed that varying C/N ratios had a more pronounced effect on the production of nitrogenous EPS constituents than their carbon counterparts. This isotope labeling approach can be used to determine mass balances in activated sludge systems.
