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.

A Gram-stain-negative, facultatively anaerobic, non-motile, rod-shaped bacterial strain, designated HL-MP18T, was isolated from Arctic seawater after a prolonged incubation employing polypropylene as the sole carbon source. Phylogenetic analyses of 16S rRNA gene sequence revealed that strain HL-MP18T affiliated to genus Roseovarius with close relatives carneus LXJ103T (96.8 %) and litorisediminis KCTC 32327T (96.5 %). The complete genome comprised circular chromosome 3.86 Mbp two plasmids 0.17 0.24 Mbp. Genomic comparisons based on average nucleotide identity digital DNA-DNA hybridization showed consistently discriminated its closely related taxa in Roseovarius.

ABSTRACT Polycyclic aromatic hydrocarbons (PAHs) are common toxic and carcinogenic pollutants in marine ecosystems. Despite their prevalence these habitats, relatively little is known about the natural microflora biochemical pathways that contribute to degradation. Approaches investigate microbial PAH degraders often heavily rely on genetic biomarkers, which requires prior knowledge of specific degradative enzymes genes encoding them. As such, biomarker-reliant approaches cannot efficiently identify novel degradation or degraders. Here, we screen 18 bacterial strains representing Pseudomonadota, Bacillota, Bacteroidota phyla for two model PAHs, pyrene (high molecular weight) phenanthrene (low weight). Using a qualitative plate screening assay, determined 16 show some ability degrade either both compounds. Degradative was subsequently confirmed with quantitative high-performance liquid chromatography approach, where an additional strain showed culture. Several members prominent Roseobacteraceae family degraded varying efficiency (1.2%–29.6% 5.2%–52.2%, respectively) over 26 days. Described biomarkers were absent all degrading genome sequences available, suggesting harbor transformation pathways. These results demonstrate utility culture-based expanding landscape concerning systems. IMPORTANCE hydrocarbon (PAH) pollution widespread throughout environments significantly affects native flora fauna. Investigating microbes responsible PAHs provides greater understanding attenuation In addition, use inform bioinformatic omics-based useful identifying mechanisms elude biomarker-based investigations. Furthermore, allow study co-metabolism, increasingly appears be mechanism microbes.
