A novel FadL family outer membrane transporter is involved in the uptake of polycyclic aromatic hydrocarbons.

Unlabelled: Gram-negative bacteria play a pivotal role in the bioremediation of persistent organic pollutants, such as polycyclic aromatic hydrocarbons (PAHs). Because the outer membrane (OM) of these bacteria hinders the direct permeation of hydrophobic substances into the cells, trans-OM proteins are required for the uptake of PAHs. However, neither the characteristics of PAH transporters nor the specific transport mechanism has been well interpreted.

[Advances in microbial whole-cell sensors for the detection of aromatic compounds].

The inherent stability and recalcitrance of benzene ring structures render aromatic compounds a major ecological concern and a substantial risk to human health. Hence, developing a facile and efficacious detection technique for aromatic compounds is essential. As our comprehension of aromatic compound characteristics deepens, microbial cell-based biosensors have emerged as increasingly popular tools in the detection of aromatic compounds.
