Silent signals: how N-acyl homoserine lactones drive oral microbial behaviour and health outcomes

Frontiers in Oral Health
BackgroundN-acyl homoserine lactones (AHLs) are small signalling molecules predominantly secreted in Gram-negative bacteria.ObjectiveThe aim is to provide a comprehensive overview of AHLs in oral health.MethodsTwo independent researchers conducted a ...

Flavones as Quorum Sensing Inhibitors Identified by a Newly Optimized Screening Platform Using Chromobacterium violaceum as Reporter Bacteria

Molecules, 2016
Quorum sensing (QS) is the process by which bacteria produce and detect signal molecules to coordinate their collective behavior. This intercellular communication is a relevant target for anti-biofilm therapies.

The sRNA vvrr1 Modulates the VarS/VarA‐Csr System via LeuO to Regulate Biofilm Formation and Virulence in Vibrio alginolyticus

Animal Research and One Health, EarlyView.
vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.

Bacterial quorum sensing and food industry [PDF]

, 2011
Food spoilage and biofilm formation by food-related bacteria are significant problems in the food industry. Even with the application of modern-day food preservative techniques, excessive amounts of food are lost due to microbial spoilage.

Effects of natural and chemically synthesized furanones on quorum sensing in Chromobacterium violaceum

BMC Microbiology, 2004
Background Cell to cell signaling systems in Gram-negative bacteria rely on small diffusible molecules such as the N-acylhomoserine lactones (AHL). These compounds are involved in the production of antibiotics, exoenzymes, virulence factors and biofilm ...

Induction and Enhancement of Bacteriocin Production (Review)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Conventionally, bacteriocins are produced by microorganisms on complex substrates, released as semi‐purified preparations or crude fermentates. These bacteriocin‐containing products often exhibit unsatisfactory purity, low active‐substance content, and high production costs, limiting their commercialization and use. This review aims to analyze

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Autonomous Control of Gene Expression Using Endogenous Transcription Signals

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Autonomous cell‐based control of heterologous gene expression can simplify batch‐culture bioprocessing by eliminating external monitoring and extrinsic control of culture conditions. Existing approaches use auto‐induction media, synthetic cell‐cell communication systems, or application‐specific biosensors.
