Summary: This study investigated the distribution of PAH degraders at two different petroleum hydrocarbon-polluted sites in the Niger Delta and demonstrated the ability of indigenous microbes to utilize these PAHs. The findings suggest that these indigenous microbes can be used to effectively remove PAHs from oil-polluted soils through bioremediation.

Summary: In this study, a highly efficient natural PHE-degrading microbial consortium HJ-SH was isolated from soil contaminated with PHE. The consortium showed a degradation efficiency higher than any other natural or engineered strains reported so far. Seven dominant strains were identified from the consortium, and one strain, SH-4, showed the strongest PHE degradation ability. The consortium exhibited high tolerance for PHE and was capable of degrading other organic pollutants as well. An artificial consortium HJ-7 was constructed, which outperformed the natural consortium HJ-SH in terms of reproducibility, application stability, and modification potential.

Summary: A strain of Achromobacter xylosoxidans BP1 with superior PAHs degradation ability was isolated from contaminated soil in northern China, providing a viable solution for bioremediation of PAHs-contaminated soil. The removal rates of phenanthrene (PHE) and benzo[a]pyrene (BaP) by strain BP1 were 98.47% and 29.86% after 7 days, respectively. BP1 significantly enhanced the removal of PHE and BaP in PAH-contaminated soil, with a removal rate of 67.72% and 13.48% over 49 days.

Summary: This study investigated the effect of microorganisms on the degradation of BIT residues in different soil conditions using 16S rRNA gene sequencing. The results showed significant changes in the structure and abundance of bacterial communities in BIT soils, while there was no significant difference in the fungal community. Certain bacterial phyla played a crucial role in the degradation of BIT, and soil organic matter and pH had significant effects on the microbial community.

Summary: This study reports a bacterial consortium (Pdy-1) isolated from paddy rice soil in northern Japan, which is capable of degrading polycyclic aromatic hydrocarbons (PAHs) at high rates. The consortium consists of Achromobacter (40%), Castelaniella, Rhodanobacter, and Hypomicrobium (each 7%), and other detected bacteria include Comamonas, Ferrovibrio, Terrimonas, Bordetella, Rhizobium, and Pseudonocardia. Real-time PCR results showed that PAH degrading genes such as PAH-RDH and nidA were most abundant at day 5 when rapid biodegradation of PAHs was observed. This study enhances our understanding of an effective PAH-degrading bacterial consortium from paddy rice soil.

Summary: The text discussed the significant rise in polycyclic aromatic hydrocarbons (PAHs) contamination over the past century due to intensified industrial activities, and highlighted the widespread distribution of PAHs in various ecosystems. It also emphasized on the microbial degradation of PAHs using diverse microorganisms and various cultivation conditions that govern the rate of degradation.

Summary: Microbial community succession during the enrichment of crude-oil-degrading bacteria was analyzed using Illumina high-throughput sequencing. Rhodococcus sp. OS62-1, Dietzia sp. OS33, and Pseudomonas sp. P35 were isolated and used to construct a bacterial consortium with high crude-oil-degrading efficiency, providing technical support for bioremediation of crude oil pollution.

Summary: The study reveals that OCPs-impacted soil is contaminated with 15 OCPs and suffers from nitrate and phosphorous deficiencies, with 10 of the OCPs posing severe ecological risks. Key microbiomes in the impacted soil include Enterobacteriaceae and Mortierellaceae, with the low abundance of Nitrospirae species and extinction of Glomeromycota suggesting serious toxicological consequences of the OCPs.

Summary: The study suggests that utilizing a consortium of sponge symbiont bacteria is a feasible and promising approach for degrading PAHs. In experiments with anthracene and pyrene, the consortium was effective in degrading both compounds, with pyrene showing a lower degradation rate. The degradation products mainly consist of alcohols, aldehydes, carboxylic acids, and a small proportion of aromatic hydrocarbon components.

Summary: The laboratory experiment examined the medium-term influence of three tetracycline antibiotics on soil enzymes and microbial communities in four agricultural soils. It was found that there was a residual effect on microbial parameters, with different microbial sensitivity depending on soil type and properties. The PLFA patterns showed different microbial communities depending mainly on soil type and the type of antibiotic, demonstrating potential environmental relevance for health risk assessment in soils.

Summary: This study investigated the mineralization of pyrene on urban holm oak leaves by autochthonous microorganisms and a PAH degrading bacterium. It found that the mineralization rate differed between the two types of microorganisms and that the presence of particulate matter on leaf surfaces influenced the accumulation of pyrene and microbial activity.

Summary: This study evaluates the biodegradation capacity and succession of microbial communities in Nigerian soils, finding that the degradation of natural and synthetic oils differ, possibly due to the interference of sulfur content. Microbial communities from highly contaminated soil showed higher degradation capacity and community size compared to those from less contaminated soil. By optimizing culturing conditions and inoculating specific bacteria, the biodegradation of crude oil can be improved.

Summary: Cover crops enhance soil microbial community biomass and affect community structure compared to no cover crops, with responses varying depending on soil type, climatic conditions, and cover crop types. Incorporating cover crop residue into the soil can increase certain microbial parameters but decrease others.

Summary: Polycyclic aromatic hydrocarbons (PAHs) are major pollutants found in contaminated sites and often coexist with other polyaromatic compounds. This study identified Immundisolibacter as the key population involved in the degradation of benz(a) anthracene (BaA) and discovered novel aromatic ring-hydroxylating dioxygenases (RHD) in this genus. The presence of other high molecular weight PAHs in soil microcosms delayed the biodegradation of BaA and triggered microbial interactions.
