Biodegradation of polystyrene nanoplastics by Achromobacter xylosoxidans M9 offers a mealworm gut-derived solution for plastic pollution.

Nanoplastics pose significant environmental problems due to their high mobility and increased toxicity. These particles can cause infertility and inflammation in aquatic organisms, disrupt microbial signaling and act as pollutants carrier. Despite extensive studies on their harmful impact on living organisms, the microbial degradation of nanoplastics is still under research.

Anti-quorum sensing activity of some marine bacteria isolated from different marine resources in Egypt.

Objectives: To screen for a variety of marine bacteria with anti-quorum sensing and anti-biofilm activities.

Results: Among 188 bacterial isolates from water, sediment, and corals in the Red Sea region, approximately 35% (65 isolates) of the isolates displayed a significant degradation in the purple pigment of the bioreporter strain without affecting cell growth. The quorum quenching bacteria obtained from coral-associated bacteria were 66.
