Unlabelled: Mercury pollution is a kind of heavy metal pollution with great harm and strong toxicity which exists worldwide. Some microorganisms can convert highly toxic methylmercury into inorganic mercury compounds with significantly reduced toxicity. This is an effective means of methylmercury pollution remediation.

As a universal language across the bacterial kingdom, the quorum sensing signal autoinducer-2 (AI-2) can coordinate many bacterial group behaviors. However, unknown AI-2 receptors in bacteria may be more than what has been discovered so far, and there are still many unknown functions for this signal waiting to be explored. Here, we have identified a membrane-bound histidine kinase of the pathogenic bacterium , AsrK, as a receptor that specifically detects AI-2 under low boron conditions.

Polyunsaturated fatty acids (PUFAs) play a crucial role in aiding bacteria to adapt to extreme and stressful environments. While there is a well-established understanding of their production, accrual, and transfer within marine ecosystems, knowledge about terrestrial environments remains limited. Investigation of the intestinal microbiome of earthworms has illuminated the presence of PUFAs presumably of microbial origin, which contrasts with the surrounding soil.

Unlabelled: Remote polar regions offer unique opportunities and significant challenges for antimicrobial resistance research in a near-pristine environment. While core microbiology techniques continue to have an important role in supporting environmental research, the severe cold climate presents considerable challenges to laboratory research. We explore adaptations required for core bacteriology investigations in polar regions on an unsupported remote expedition c.
