The Impact of the Mechanism of Biocarriers on Bacterial–Microbial Symbiosis for Mariculture Wastewater Treatment: Performance and Microbial Community Evolution

Water, Journal Year: 2025, Volume and Issue: 17(8), P. 1127 - 1127

Published: April 10, 2025

Mariculture wastewater is an intractable wastewater, owing to its high salinity inhibiting microbial metabolism. The biocarrier bacterial–microbial consortium (BBM) and (BM) were developed investigate the mechanism of pollutant degradation community evolution. BBM exhibited excellent mariculture treatment, with highest removal for TOC (91.78%), NH4+-N (79.33%) PO43−-P (61.27%). Biocarriers accelerated anaerobic region formation, levels denitrifying bacteria accumulation improving nitrogen in BBM. Moreover, enhanced production soluble products (SMPs) (11.53 mg/L) extracellular polymeric substances (EPSs) (370.88 mg/L), which formation bacterial microalgal flocs fluorescence excitation–emission matrix (EEM) results demonstrated that addition biocarriers successfully decreased aromatic-like components anoxic aerobic supernatants. Additionally, shifted constitutions significantly. provided microenvironment, enrichments Rhodobacteraceae (66%) Ruegeria (70%), a satisfying denitrification This study novel system actual treatment.

Linking the Metabolic Activity of Plastic-Degrading Fungi to Their Taxonomy and Evolution

Journal of Fungi, Journal Year: 2025, Volume and Issue: 11(5), P. 378 - 378

Published: May 15, 2025

Plastic, a ubiquitous part of our daily lives, has become global necessity, with annual production exceeding 300 million tons. However, the accumulation synthetic polymers in environment poses pressing challenge. To address this urgent issue, fungi have emerged as potential agents for plastic degradation. In previous manuscript, ‘A Review Fungi That Degrade Plastic’, we explored taxonomic placement plastic-degrading across three main phyla: Ascomycota, Basidiomycota, and Mucoromycota. review, built upon that foundation aimed to further explore relationships these comprehensive detailed manner, leaving no stone unturned. Moreover, linked metabolic activity enzyme their taxonomy summarized phylogenetic tree table on presented here. Microbial enzymes are key players polymer degradation, operating intra-cellularly extra-cellularly. Fungi, one well-studied groups microbes respect at forefront addressing issue accumulation. Their unique ability hydrolyze produce wide range specific is testament potential. gather synthesize information concerning pathways involved degradation plastics. The manuscript explores diverse can major metabolism. We provide listing 14 fungal (Esterase, Cutinase, Laccase, Peroxidases, Manganese peroxidase, Lignin Oxidoreductases, Urease, Protease, Lipase, Polyesterase, Dehydrogenase, Serine hydrolase, PETase) alongside relevant known enzymes. Furthermore, integrate fungi’s enzyme-producing capabilities phylogeny. Taxonomic investigations pinpointed primary classes (Eurotiomycetes, Sordariomycetes (Ascomycota), Agaricomycetes (Basidiomycota)) significant degraders vital mentioned earlier. This paper provides foundational resource recognizing involvement biodegradation polymers. It will ultimately advance biotechnology efforts natural environments.

Unraveling Microplastic-Biofilm Nexus in Aquaculture: Diversity and Functionality of Microbial Communities and Their Effect on Plastic Traits

ACS ES&T Water, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 12, 2024

Microplastics (MPs) serve as unconventional platforms for microorganisms and vectors pollutants pathogens in aquatic ecosystems. This study explored the dynamics of microbial colonization biofilm formation on MPs, a key factor their ecological impact, using five common MP types─poly(ethylene terephthalate) (PET), poly(vinyl chloride) (PVC), polyethylene (PE), polylactic acid (PLA), polypropylene (PP)─incubated an aquaculture pond 128 days. The biomass increased by 173–617% compared with original samples, especially PP- PE-MPs (OD 595 nm = 0.30 0.28, respectively). Driven inherent properties community structure differed significantly across types, leading to varied changes hydrophobicity surface morphology. Differences physicochemical cause each type selectively enrich specific microbes, profoundly influencing degradation potential. Notably, supported rich, mature biofilms conducive carbon cycling development, while PET-MPs attracted more abundant plastic degraders, like Pseudomonas. also highlighted enrichment indicating potential environmental human health risk. These findings illuminate complex interactions between characteristics dynamics, enhancing understanding MPs' behaviors fates settings.
