“…The anti-QS activity of Bacillus strains was identified through the QQ activity of lactonase and the antagonistic effect of DKPs on QS receptors. Li et al (2022a) [ 81 ] showed that QS promoted the growth of Lb. plantarum ss-128, but they did not investigate its anti-QS activity against spoilage bacteria.…”

Background: Quorum sensing (QS) is a cell-to-cell communication mechanism that occurs between inter- and intra-bacterial species and is regulated by signaling molecules called autoinducers (AIs). It has been suggested that probiotics can exert a QS inhibitory effect through their metabolites. Purpose: To provide an overview of (1) the anti-QS activity of probiotics and its mechanism against foodborne pathogenic and spoilage bacteria; (2) the potential role of the QS of probiotics in gut health; and (3) the impact of microencapsulation on QS. Results: Lactobacillus species have been extensively studied for their anti-QS activity and have been found to effectively disrupt QS in vitro. However, their effectiveness in a food matrix is yet to be determined as they interfere with the AI receptor or its synthesis. QS plays an important role in both the biofilm formation of probiotics and pathogenic bacteria. Moreover, in vitro and animal studies have shown that QS molecules can modulate cytokine responses and gut dysbiosis and maintain intestinal barrier function. In this scenario, microencapsulation was found to enhance AI activity. However, its impact on the anti-QS activity of probiotics and its underlying mechanism remains unclear. Conclusions: Probiotics are potential candidates to block QS activity in foodborne pathogenic and food spoilage bacteria. Microencapsulation increases QS efficacy. However, more research is still needed for the identification of the QS inhibitory metabolites from probiotics and for the elucidation of the anti-QS mechanism of probiotics (microcapsules and free cells) in food and the human gut.

This study consisted in the formulation and evaluation of the organoleptic, physicochemical, and microbiological qualities of nectars and jam prepared from Vitex doniana fruit. Nectars (five types) consisted of two acidulated with lemon, two acidulated with tamarind with pH values of 3.45 and 3.55, and a control. Jams (three types) were made as one acidulated with lemon, one acidulated with tamarind with a pH value of 3.88, and a control with a pH value of 4.44. The Brix values were 10.75 and 60.00 for all nectars and jam, respectively. The total sugar content of the nectars ranged from 9.52 ± 0.04 (NC1) to 9.11 ± 0.03% (T) and that of the jams from 58.27 ± 0.02% to 49.97 ± 0.01%. It appeared that prepared nectar and jam samples were of good microbiological quality, confirming compliance with good hygiene and manufacturing practices throughout the process and compliance with Algerian and Luxembourg standards.
