“…After some results showed that the QQ bacteria located at the periphery of a bead can degrade signal molecules more than the QQ bacteria located inside of the bead have come to light, it was needed to create new immobilization media designs. In 2016, another QQ study with QQ-hollow cylinder was also presented to the readers and this newly developed immobilization medium could increase the surface area and eliminate the disadvantage of hollow fibers used as an immobilization medium [129]. QQ-hollow cylinder presented higher QQ activity than did the QQ beads.…”

“…Furthermore, the shape of the QQ-hollow cylinder provided more physical contact between media and biofilm and this led to a higher efficiency of physical washing. The final step for the immobilization medium design and development is small QQ-sheets that showed 2.5-fold higher biological QQ activity when compared to the QQ activity of QQ beads [129]. Besides, immobilization of QQ enzymes on the membrane surface has been a hot issue and stability problems for enzyme immobilization for QQ applications have started to be recently solved [130].…”

In comparison to alternative advanced wastewater treatment technologies, the main problem associated with membrane bioreactor (MBR) technology, which has become prominent in recent years, is biofouling. Within these systems, biofouling is typically the result of a biofilm layer resulting from bacterial gathering. One biological system that can be employed to interrupt the process of bacterial gathering is called 'Quorum Quenching (QQ)'. Existing QQ applications can be classified using three main types: 1) bacterial/whole-cell applications, 2) direct enzyme applications, and 3) natural sourced compounds. The most common and widely recognized applications for membrane fouling control during MBR operation are bacterial and direct enzyme applications. The purpose of this review was to identify and assess biofilm formation mechanism and results, the suggestion of the QQ concept and its potential to control biofilm formation, and the means by which these QQ applications can be applied within the MBR and present QQ MBR studies.

“…Quorum sensing is reported to play an important role in membrane fouling and EPS production. [13][14][15][16][17] However, it is unclear yet that the foulant production via quorum sensing is significant in bulk sludge or in cake layer. Quorum sensing has positive feedback mechanism to produce more signal molecules triggered by the presence of signal molecules at higher concentration than threshold.…”

“…Degradation of quorum sensing signal molecules by acylase or specific bacteria, called "quorum quenching", is reported to be effective to reduce membrane fouling. [13][14][15][16][17] This is probably because quorum sensing triggers production of EPS, which are the major foulant in MBR. [18][19][20] However, among various species of AHL, it is still unclear what AHL species are important to induce microbial group behaviors that affect treatment performance and membrane fouling.…”

Diversity of N-acyl homoserine lactones in activated sludge detected by Fourier transform mass spectrometry

Quorum sensing is recently considered to play important roles in biological wastewater treatment processes. This study aimed to investigate diversity of N-acyl homoserine lactones (AHL) among biological wastewater treatment processes and their locations. We analyzed and quantified 10 AHL in activated sludge at wastewater treatment plants (WWTPs) by Fourier transform mass spectrometry (FTMS) and by bioassay on thin-layer chromatography (TLC). Sludge samples were taken at seven WWTPs in Japan and in Thailand, which were chosen to compare different process types including a pilot-scale membrane bioreactor process. Various AHL were detected in activated sludge, suggesting the presence of quorum sensing activity in many practical WWTPs. Detection of AHL by LC-FTMS was much more sensitive than by TLC bioassay, because TLC bioassay was implied to be affected by the presence of quorum quenching molecules in activated sludge. With LC-FTMS analysis, AHL, which has short straight chain in the acyl group, were more abundant. Especially, C 4 -HSL, C 7 -HSL, and C 8 -HSL were detected widely independent of locations and process types. AO processes had higher AHL productivity than other processes.npj Clean Water (2019) 2:11 ; https://doi.

“…In this study, seven kinds of QQ bacteria were sampled from the foulants of reverse osmosis (RO) membrane and used in a microbial filter for biofouling control of a MBR. The results showed six kinds of encapsulated microbial filters demonstrated a substantial inhibitory effect on membrane biofouling.In another study,Nahm et al (2017) developed a new QQ medium-type bacterial capture sheet (QQ-sheet)…”
