Lignin is a complex biopolymer comprising phenolic monomers with different degrees of methoxylation and may potentially enhance the degradation of soil pollutants such as polycyclic aromatic hydrocarbons (PAHs) through co-metabolism. However, the contribution of lignin constituents, including phenolic and methoxy subunits, to PAH biodegradation remains unclear. Here, p-hydroxybenzoate (pHBA), vanillate and methanol were selected to simulate phenolic units and methoxy groups of lignin.

- PBDEs (polybrmoninated diphenyl ethers) are pollutants that harm microorganisms, with their impact influenced by temperature in environmental settings.
- A study incubated soil microcosms with BDE-15 at various temperatures (4 °C, 20 °C, 37 °C, and ambient) for up to 180 days, revealing that most BDE-15 remained unchanged and only minor degradation occurred.
- The research found that lower temperatures significantly altered bacterial community dynamics, indicating greater ecological risks, while higher temperatures had minimal effects on community characteristics and interactions.
