“…The effect of different AHLs on the bacterial growth was evaluated according to the method of Jie et al (2018). Overnight culture of P. fluorescens (OD 600 = 1) was diluted at 1:100 ratio in fresh LB broth containing 2 μg/mL of different AHLs (C 4 -HSL, C 6 -HSL, C 8 -HSL, C 10 -HSL, C 12 -HSL, and C 14 -HSL), respectively.…”

Some bacteria can modulate their spoilage potential by responding to environmental signaling molecules via the quorum sensing (QS) system. However, the ability of Pseudomonas fluorescens, the specific spoilage organism (SSO) of turbot, to response to environmental signaling molecules remains unclear. This study investigated the effects of six synthetic N-acyl homoserine lactones (AHLs) on typical behaviors mediated by QS in P. fluorescens, such as biofilm formation and extracellular protease activity. Total volatile basic nitrogen (TVB-N) was used as a spoilage indicator to evaluate quality changes in AHL-treated turbot filets during storage. The results confirm the enhancing effect of environmental AHLs on QS-dependent factors of P. fluorescens and quality deterioration of turbot filets, with C4-HSL and C14-HSL being the most effective. Moreover, the content decrease of exogenous AHLs was also validated by gas chromatography–mass spectrometry analysis. Further, changes in rhlR transcription levels in P. fluorescens suggest that this bacterium can sense environmental AHLs. Finally, molecular docking analysis demonstrates the potential interactions of RhlR protein with various exogenous AHLs. These findings strongly implicate environmental AHLs in turbot spoilage caused by P. fluorescens, suggesting preservation of turbot should not exclusively consider the elimination of SSO-secreted AHLs.

“…Microaerobic conditions are favourable to these bacteria, they act on the degradation of organic matter and impact various cycles of matter due to their versatile respiratory network. The genus was shown to be implicated in the degradation of micro-and macroorganisms (Dos Santos et al 1998;Nealson and Scott 2006;Richards et al 2008;Kakizaki et al 2009;Skrlin et al 2011;Janda and Abbott 2014;Petit et al 2015;Martin et al 2015;Jie et al 2018;Yagi et al 2018). Organic matter degradation provides formate, lactate or pyruvate, simple or complex sugars, fatty acids, nucleosides, amino acids, osmolytes or more exotic organic compounds that are all used as carbon, nitrogen, and phosphorus sources but also to sustain a diversified and adaptable respiratory network (Fig.…”

“…Bacteria-bacteria interactions have also been underlined in work dealing with the recycling of organic matter (Jie et al 2018;Zhu et al 2018) Indeed, it has been shown that the quorum sensing mechanism is important for Shewanella growth during degradation of refrigerated fish. However, the Shewanella strain from this study can sense the signal molecule from quorum sensing but it cannot produce it (Jie et al 2016).…”

The Gram-negative Shewanella bacterial genus currently includes about 70 species of mostly aquatic γ-proteobacteria, which were isolated around the globe in a multitude of environments such as surface freshwater and the deepest marine trenches. Their survival in such a wide range of ecological niches is due to their impressive physiological and respiratory versatility. Some strains are among the organisms with the highest number of respiratory systems, depending on a complex and rich metabolic network. Implicated in the recycling of organic and inorganic matter, they are important components of organism-rich oxic/anoxic interfaces, but they also belong to the microflora of a broad group of eukaryotes from metazoans to green algae. Examples of long-term biological interactions like mutualism or pathogeny have been described, although molecular determinants of such symbioses are still poorly understood. Some of these bacteria are key organisms for various biotechnological applications, especially the bioremediation of hydrocarbons and metallic pollutants. The natural ability of these prokaryotes to thrive and detoxify deleterious compounds explains their use in wastewater treatment, their use in energy generation by microbial fuel cells and their importance for resilience of aquatic ecosystems.

“…It's widely believed that QS can regulate bacteria growth and metabolism, such as Pseudomonas aeruginosa (Flickinger et al 2011) and Shewanella baltica (Jie et al 2018). PLA production levels may be relevant to the complicated energy transduction (glucose metabolism), different enzyme system and the influence of peptide supply and cosubstrate (Vermeulen et al 2006;Mu et al 2012).…”

3-Phenyllactic acid (PLA) is a novel and natural antimicrobial compound. However, the concentration of PLA produced by native microbes was rather low. To enhance the production of PLA of Lactobacillus plantarum AB-1, the microcapsules of L. plantarum AB-1 cells with a high quorum-sensing capacity was established and investigated. In addition, the relation between PLA production and quorum sensing was further investigated and confirmed by adding the exogenous 4,5-dihydroxy-2,3-pentanedione (DPD, AI-2 precursor). The results indicated that the PLA production of L. plantarum AB-1 in microencapsulated cells (MC cells) was higher than that of the free cells, and the lactate dehydrogenase activity, autoinducer-2 (AI-2) levels and the relative expression of the luxS gene were also significantly increased in MC cells (P \ 0.05). In addition, the cell growth, AI-2 levels and PLA production of L. plantarum AB-1 were also significantly promoted after adding 24 lM exogenous DPD. The results suggest that the PLA production of L. plantarum was partly regulated by the AI-2/LuxS system, and microencapsulation can increase the local AI-2 level and enhance QS capacity, which are beneficial to PLA production. The results may provide a new insight and experimental basis for the industrial production of PLA.
