This study aimed to evaluate the impact of co-inoculation sp. and sp. on plant ( L.) growth in the presence of polycyclic aromatic hydrocarbon (PAH) contamination (anthracene, phenanthrene, and pyrene). Eight strains from the genus bv. were selected for biotest analysis. Two methods of inoculation were used in the chamber experiment: (1) alone and (2) a combined inoculant ( and ). For comparison, non-contaminated controls were also used. The results demonstrated that co-inoculation of plants with and resulted in more root and shoot biomass than in plants inoculated with alone. The results indicated that application of a co-inoculation of bacteria from and species had a positive effect on clover nodulation and growth under the condition of PAH contamination.

Atmospheric particulate matter (PM) is one of the most dangerous air pollutants of anthropogenic origin; it consists of a heterogeneous mixture of inorganic and organic components, including transition metals and polycyclic aromatic hydrocarbons. Although previous studies have focused on the effects of exposure to highly concentrated PM on the respiratory and cardiovascular systems, emerging evidence supports a significant impact of air pollution on the gastrointestinal (GI) tract by linking exposure to external stressors with conditions such as appendicitis, colorectal cancer, and inflammatory bowel disease. In general, it has been hypothesized that the main mechanism involved in PM toxicity consists of an inflammatory response and this has also been suggested for the GI tract.

Six new sesquiterpenes, including four eremophilane derivatives fureremophilanes A-D (-) and two acorane analogues furacoranes A and B ( and ), were characterized from the culture extract of the cold-seep derived fungus CS-280 co-cultured with autoclaved QDIO-4. All the six compounds were highly oxygenated especially and with infrequent epoxyethane and tetrahydrofuran ring systems. The structures of - were established on the basis of detailed interpretation of 1D and 2D NMR and MS data.

Benzo[a]pyrene (B[a]P) is a hazardous polycyclic aromatic hydrocarbon that accumulates in several environmental matrices as a result of incomplete combustion. Its presence, carcinogenic properties, and tendency for bioaccumulation provide significant risks to human health and the environment. The objective of this study is to create an immunoassay for the detection of benzo[a]pyrene utilizing immunoglobulin Y antibodies.

Deep sea microbial communities play a significant role in global biogeochemical processes. However, the depth-wise metabolic potential of microbial communities in hydrothermally influenced Central Indian Ridge (CIR) and Southwest Indian Ridge (SWIR) remains elusive. In this study, a comprehensive functional microarray-based approach was used to understand factors influencing the metabolic potential of microbial communities and depth-driven differences in microbial functional gene composition in CIR and SWIR.

Lanthipeptides are ribosomally synthesized and post-translationally modified peptides (RiPPs) characterized by the presence of thioether cross-links called lanthionine and methyllanthionine, formed by dehydration of Ser/Thr residues and Michael-type addition of Cys side chains onto the resulting dehydroamino acids. Class II lanthipeptide synthetases are bifunctional enzymes responsible for both steps, thus generating macrocyclic natural products. ProcM is part of a group of class II lanthipeptide synthetases that are known for their remarkable substrate tolerance, having large numbers of natural substrates with highly diverse peptide sequences.
