Biodegradation Potential of Microorganisms in Hydrocarbon-Polluted Baltic Sea Sediments

Published: Jan. 1, 2025

The spill of crude oil and petroleum derivatives comprises the majority oceans pollution leads to acute chronic damages exposed organisms coastal communities. Some bacteria fungi are able biodegrade hydrocarbons both in terrestrial aquatic environments. Sediments taken from Baltic Sea vicinity one terminal, Curonian Lagoon strait with high anthropogenic shipping pressure a source microorganisms having potential degrade products. Next generation sequencing (NGS) identified taxa (e.g. Thalassolituus, Exiguobacterium) were indicative consistent presence sediments. Through enrichment sediments samples oil, marine diesel lubricating line NGS study results, we isolate several strains oil-degrading belonging genera Pseudomonas Priestia, members family Lysobacteriaceae; as well Dipodoscaceae, Dipodoscales incertae sedis, Yarrowia, Cyberlindnera, Geotrichum, Pichia, Candida Fusarium. results suggest that bacterial fungal communities present demonstrate significant for bioremediation other pollutants.

Seasonal dynamics of bacterial communities in mangrove sediments of Shupaisha island, Zhejiang Province, China

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Published: Feb. 19, 2025

Mangrove forests, found primarily in tropical and subtropical coastal regions, support diverse microbial communities that are crucial for nutrient cycling energy flow then sustain mangrove ecosystem integrity. This study investigated the seasonal dynamics of bacterial sediments Shupaisha island (Zhejiang Province, China) through amplifying high-throughput sequencing 16S rRNA gene fragments. Proteobacteria (23.59-44.40%), Actinobacteria (4.92-19.01%), Bacteroidetes (4.31-22.79%) dominated phyla with highest diversity indices winter. were more abundant during winter (13.27%) spring (14.36%), while abundance was summer, significantly correlating temperature. Significant differences community composition observed between autumn exhibited similar distribution, indicating a transitional pattern dynamics, temperature sand content being most influential factors. enhances our understanding characteristics ecosystems, potentially providing valuable insights into monitoring assessing health stability ecosystems Zhejiang Province.

Living in mangroves: a syntrophic scenario unveiling a resourceful microbiome

BMC Microbiology, Journal Year: 2024, Volume and Issue: 24(1)

Published: June 28, 2024

Abstract Background Mangroves are complex and dynamic coastal ecosystems under frequent fluctuations in physicochemical conditions related to the tidal regime. The variation organic matter concentration, nutrients, oxygen availability, among other factors, drives microbial community composition, favoring syntrophic populations harboring a rich diverse, stress-driven metabolism. known for their carbon sequestration capability, integrated metabolic activity is essential global biogeochemical cycling. Here, we present reconstruction based on genomic functional capability flux profile between sympatric MAGs co-assembled from tropical restored mangrove. Results Eleven were assigned six Bacteria phyla, all distantly available reference genomes. showed several potential coupling points shortcuts complementary routes predicted interactions. Two scenarios drawn: heterotrophic scenario with plenty of sources an autotrophic limited or inhibitory conditions. sulfur cycle was dominant over methane major pathways identified acetate oxidation coupled sulfate reduction, acetogenesis carbohydrate catabolism, ethanol production fixation. Interestingly, gene sets similar those described wastewater effluent treatment processes identified. Conclusion mangrove reflected flexibility required survive fluctuating environments as microhabitats created by regime sediments. components strongly suggest that communities could represent resourceful model biotechnological applications occur naturally environment.

Unveiling the bacterial diversity and potential of the Avicennia marina ecosystem for enhancing plant resilience to saline conditions

Environmental Microbiome, Journal Year: 2024, Volume and Issue: 19(1)

Published: Dec. 4, 2024

Abstract Background Avicennia marina ecosystems are critical for coastal protection, water quality enhancement, and biodiversity support. These unique thrive in extreme saline conditions host a diverse microbiome that significantly contributes to plant resilience growth. Global food security is increasingly threatened by crop yield losses due abiotic stresses, including soils. Traditional breeding salt tolerance both costly time-consuming. This study explores the potential of bacteria from A. enhance growth under conditions, emphasizing their ecological significance. Results We analyzed Red Sea coast using high-throughput Illumina sequencing culture-dependent methods across various compartments (bulk soil, rhizosphere, rhizoplane, roots, leaves). Our findings revealed distinct compartment-specific microbial communities, with Proteobacteria being dominant phylum. Functional predictions indicated roles metal uptake promotion (PGP). Remarkably, our allowed us recover 56% bacterial diversity present microbiome, resulting isolation characterization 256 strains. isolates were screened PGP traits, heat tolerance, siderophore production, pectinase activity. Out 77 tested, 11 demonstrated significant ability Arabidopsis stress. Conclusions highlights significance mangrove microbiomes culture collections offering innovative solutions restoration production conditions. The collection bacteria, particularly rhizosphere endophytes, showcases traits stress capabilities. emphasize importance functional such as recruitment endophytic plants over taxonomic affiliation. identified strains hold not only developing biofertilizers improve productivity but also projects aimed at rehabilitating saline-degraded lands, thereby contributing overall ecosystem health sustainability.
