Degradation potential of alkanes by diverse oil-degrading bacteria from deep-sea sediments of Haima cold seep areas, South China Sea

Frontiers in Microbiology, Год журнала: 2022, Номер 13

Опубликована: Окт. 19, 2022

Marine oil spills are a significant concern worldwide, destroying the ecological environment and threatening survival of marine life. Various oil-degrading bacteria have been widely reported in environments response to pollution. However, little information is known about culturable cold seep deep-sea environments, which rich hydrocarbons. This study enriched five consortia from sediments collected Haima areas South China Sea. Parvibaculum , Erythrobacter Acinetobacter Alcanivorax Pseudomonas Marinobacter Halomonas Idiomarina were dominant genera. Further results bacterial growth degradation ability tests indicated seven efficient alkane-degrading belonging Kangiella Limimaricola Marinobacter, Flavobacterium Paracoccus whose rates higher crude (70.3–78.0%) than that diesel (62.7–66.3%). From view carbon chain length, alkane medium chains > long short chains. In addition, aquimarina F7, venetianus F1, variabilis F8, nauticus J5, sediminis N3, sediminilitoris N6 first identified as environments. will provide insight into community structures diversity areas, Sea, offer resources bioremediation applications.

Insights into the prokaryotic communities of the abyssal-hadal benthic-boundary layer of the Kuril Kamchatka Trench

Environmental Microbiome, Год журнала: 2023, Номер 18(1)

Опубликована: Авг. 2, 2023

The Kuril-Kamchatka Trench (maximum depth 9604 m), located in the NW Pacific Ocean, is among top seven deepest hadal trenches. work aimed to investigate unexplored abyssal-hadal prokaryotic communities of this fascinating, but underrated environment.As for bacterial communities, we found that Proteobacteria (56.1-74.5%), Bacteroidetes (6.5-19.1%), and Actinobacteria (0.9-16.1%) were most represented phyla over all samples. Thaumarchaeota (52.9-91.1%) was abundant phylum archaeal communities. diversity highly by ammonia-oxidizing Nitrosopumilus, potential hydrocarbon-degrading bacteria Acinetobacter, Zhongshania, Colwellia main genera. α-diversity analysis evidenced both characterized low evenness, as indicated high Gini index values (> 0.9). β-diversity (Redundancy Analysis) that, expected, significantly affected structure co-occurrence network revealed groups covaried across zone Trench. Among them, group included OTUs (Nitrosopumilus OTU A2 A1; Acinetobacter B1), which ubiquitous trench.This manuscript represents first attempt characterize KKT zone. Our results reveal prokaryotes harbored chemolithotrophic archaea heterotrophic bacteria, did not show a distinctive pattern distribution according depth. In particular, (potential hydrocarbon degraders) genera, Nitrosopumilus (ammonia oxidizer) dominant representative diversity.

Exploring novel alkane-degradation pathways in uncultured bacteria from the North Atlantic Ocean

mSystems, Год журнала: 2023, Номер 8(5)

Опубликована: Сен. 13, 2023

Petroleum pollution in the ocean has increased because of rapid population growth and modernization, requiring urgent remediation. Our understanding metabolic response native microbial communities to oil spills is not well understood. Here, we explored baseline hydrocarbon-degrading a subarctic Atlantic region uncover potential bacteria that inhabit surface subsurface water. We conducted enrichments with 13C-labeled hydrocarbon capture fraction community actively using hydrocarbon. then combined this approach metagenomics identify community. This revealed previously undescribed uncultured unique mechanisms involved aerobic degradation, indicating temperature may be pivotal structuring communities. findings highlight gaps our complexity degradation by marine

Diversity and Hydrocarbon-Degrading Potential of Deep-Sea Microbial Community from the Mid-Atlantic Ridge, South of the Azores (North Atlantic Ocean)

Microorganisms, Год журнала: 2021, Номер 9(11), С. 2389 - 2389

Опубликована: Ноя. 19, 2021

Deep-sea sediments (DSS) are one of the largest biotopes on Earth and host a surprisingly diverse microbial community. The harsh conditions this cold environment lower rate natural attenuation, allowing petroleum pollutants to persist for long time in deep marine raising problematic environmental concerns. present work aims contribute study DSS resources as biotechnological tools bioremediation hydrocarbon polluted environments. Four deep-sea sediment samples were collected Mid-Atlantic Ridge, south Azores (North Atlantic Ocean). Their autochthonous diversity was investigated by 16S rRNA metabarcoding analysis. In addition, total 26 bacteria strains with ability utilize crude oil their sole carbon energy source isolated from samples. Eight them selected novel hydrocarbonoclastic-bacterial consortium potential degrade hydrocarbons tested experiment. Bioaugmentation treatments (with inoculum pre-grown either sodium acetate or petroleum) showed an increase degradation comparatively attenuation. Our results provide new insights into deep-ocean spill applying hydrocarbon-degrading lab-scale microcosm simulate seawater.

Predicting the Weathering Time by the Empty Puparium of Sarcophaga peregrina (Diptera: Sarcophagidae) with the ANN Models

Insects, Год журнала: 2022, Номер 13(9), С. 808 - 808

Опубликована: Сен. 5, 2022

Empty puparium are frequently collected at crime scenes and may provide valuable evidence in cases with a long postmortem interval (PMI). Here, we the of Sarcophaga peregrina (Diptera: Sarcophagidae) (Robineau-Desvoidy, 1830) for 120 days three temperatures (10 °C, 25 40 °C) aim to estimate weathering time empty puparium. The CHC profiles were analyzed by gas chromatography-mass spectrometry (GC-MS). partial least squares (PLS), support vector regression (SVR), artificial neural network (ANN) models used time. This identified 49 CHCs carbon chain length between 10 33 demonstrate that variation tendency hydrocarbon could be time, while ANN show best predictive ability among these models. work indicated puparial has certain regularity can gain insight into estimating PMI forensic investigations.

The latest discovery of sulfurous natural gas marked a breakthrough in the Cenozoic exploration southwestern margin Qaidam Basin. 16S rRNA analyses were performed on crude oil samples from H2S-rich reservoirs Yuejin, Shizigou and Huatugou profiles, to understand origin, which was also integrated with carbon hydrogen isotopes alkane sulfur H2S collected Yingxiongling Area. Results show that microorganisms can survive hypersaline reservoirs, be classified into multiple phyla, including Proteobacteria, Planctomycetes, Firmicutes, Bacteroidetes, Haloanaerobiaeota. Methanogens are abundant all three while sulfate-reducing bacteria Yuejin contributing methane components gas. carbon, Area is mixture coal-type oil-type gas, primarily derived thermal degradation, profiles originated biodegradation. isotopic analysis agrees well results, i.e., southwest Basin genesis, microbial genesis secondary importance.
