Recovery of extracellular polymeric substances (EPS) from waste sludge and their conversion into bio-based commodities play a key role in improving the economics environmental sustainability wastewater treatment. This study investigated effect EPS incorporation on self-remediation capacity diesel-polluted seawater Jiaozhou Bay. Hydrocarbons attenuation microbial activity were monitored seawaters collected five islands after diesel N, P addition, with without EPS, incubated under aerobic conditions. Compared to degradation TPH (total petroleum hydrocarbon) doubled improved non-volatile (C16-C24) hydrocarbons some extent EPS-added 60 days bioremediation. However, introduction resulted more significant changes diversity relative abundance phylum Proteobacteria Firmicutes higher cytochrome P450 gene was observed than alkB gene, indicating that might provide binding sites for degrading bacteria like genus Bacillus Pseudomonas. Prediction alkane decay genes 16S rRNA sequencing data revealed addition significantly stimulated related ethanol dehydrogenation function community, consistent trend dehydrogenase activity. In conclusion, enhanced thus accelerated pollutants, which may be due mechanism a) protects hydrocarbon stress, b) promotes biofilm formation shortens reaction time between microorganisms diesel.

Abstract Polystyrene foam, which is used as a buoyant material in mariculture, common constituent of marine plastic debris. Here, we conduct analyses on polystyrene foam debris collected the east coast Xiamen Island, China, and associated plastic-burrowing clamworms. We apply interferometry, mass spectrometry microscopy to fragments excreted by benthic clamworms ( Perinereis vancaurica ). find evidence digestion degradation during passage clamworm gut leading formation accumulation microplastics, with mean diameter 0.6 ± 0.2 mm. 16S rRNA gene sequence analysis intestines indicated diverse bacterial microbiome, dominated Acinetobacter Ruegeria bacteria. Further characterization confirmed that was degraded representative isolates johnsonii , Brevibacterium casei arenilitoris . During 30-day incubation, observed very slight decrease weight, changes chemical group thermal characteristic, production metabolic intermediates. Our findings indicate polystyrene-degrading bacteria microbiome may influence fragmentation ecosystems.

Bioaugmentation is an effective strategy used to speed up the bioremediation of marine oil spills. In present study, a highly efficient petroleum degrading bacterium (Pseudomonas aeruginosa ZS1) was applied simulated crude pollution in different sampling sites South China Sea. The metabolic pathways ZS1 degrade oil, temporal dynamics microbial community response contamination, and biofortification process were investigated. results showed that abundance diversity decreased sharply after occurrence contamination. best degradation rate which achieved samples from site N3 addition bacteria, 50.94% at 50 days. C13 alkanes totally oxidized by solid n-alkanes (C18-C20) about 70%. Based on whole genome sequencing metabolites analysis ZS1, we found degraded through terminal oxidation pathway aromatic compounds catechol pathway. This study provides data support for further research biodegradation contributes subsequent development more reasonable strategies.

Cycloalkanes pose a tremendous environmental risk due to their high concentration in petroleum hydrocarbons and hazardous effects organisms. Numerous studies have documented the biodegradation of acyclic alkanes aromatic hydrocarbons. However, insufficient attention has been paid on microbial degradation cycloalkanes, which might be closely linked psychrophilic microbes derived from low-temperature habitats. Here we show that endemic methylcyclohexane (MCH, an abundant cycloalkane species oil) consumers proliferated seawater samples Antarctic surface water (AASW). The MCH-consuming bacterial communities AASW exhibited distinct composition compared with counterparts other cold-water We also probed Colwellia Roseovarius as key active players by dilution-to-extinction-based incubation MCH sole source carbon energy. Furthermore, propose two nearly complete pathways, lactone formation aromatization, concurrently high-quality metagenome-assembled genomes consumer Roseovarius. Overall, revealed these strong interactions enhance decomposition more refractory through complementary pathways.
