In aerobic granular sludge (AGS) system, N-acyl homoserine lactones (AHLs) can effectively regulate the community structure and control filamentous bulking. It would be economically feasible to make mature granules into AHLs-rich AGS extract (AE) to replace synthesized AHLs. In this study, two SBRs were run in a fully aerobic environment and a short cycle (4 h) to culture AGS: R1 with AE adding; R2 served as control.

Anaerobic digestion (AD) is a biological process in which anaerobic microorganisms convert organic matter into methane-rich gas, contributing to the cycling of carbon and other nutrients. Quorum sensing (QS), a microbial communication mechanism, plays a critical role in regulating population-level behaviors within AD systems. This review systematically examines the roles and applications of QS in AD, emphasizing its importance in enhancing process efficiency.

Microplastics (MP) are known to be ubiquitous. The pathways and fate of these contaminants in the marine environment are receiving increasing attention, but still knowledge gaps exist. In particular, the link between mass-based MP quantification and oceanographic parameters is often lacking.

In nature, bacteria often form heterogeneous communities enclosed in a complex matrix known as biofilms. This extracellular matrix, produced by the microorganisms themselves, serves as the first barrier between the cells and the environment. It is composed mainly of water, extracellular polymeric substances (EPS), lipids, proteins, and DNA.
