Characterization of N-Acylhomoserine Lactones Produced by Bacteria Isolated from Industrial Cooling Water Systems

Sensors, 2015
The cooling water systems are used to remove heat generated in the various industries. Biofouling of the cooling water systems causes blocking of condenser pipes and the heat exchanger tubes. In many Gram-negative bacteria, N-acylhomoserine lactone (AHL)

Lysine Biosynthesis Defines a Metabolic Checkpoint for Gibberellin‐Mediated Growth in Arabidopsis thaliana

Plant, Cell &Environment, EarlyView.
ABSTRACT Lysine represents a metabolic hub linking mitochondrial energy status with amino acid catabolism, yet its role in coordinating plant growth and development remains poorly characterised. The dapat mutant, which is deficient in L,L‐diaminopimelate aminotransferase (DAPAT), exhibits severe growth inhibition associated with broad metabolic ...

Engineering of methionine-auxotroph Escherichia coli via parallel evolution of two enzymes from Corynebacterium glutamicum's direct-sulfurylation pathway enables its recovery in minimal medium

Metabolic Engineering Communications
Methionine biosynthesis relies on the sequential catalysis of multiple enzymes. Escherichia coli, the main bacteria used in research and industry for protein production and engineering, utilizes the three-step trans-sulfurylation pathway catalyzed by L ...

Calcium and Nitrogen Availability Controls Root Exudation in Hydroponically Cultured Barley

Plant, Cell &Environment, EarlyView.
ABSTRACT Root exudation is a key component of plant‐rhizosphere interactome. It is increasingly evident that root exudates influence rhizospheric microbial communities and in turn can benefit plants through improved resource allocation. However, how suboptimal nutrient availability relates to control of root exudation is poorly understood.

The phenazine pyocyanin is a terminal signalling factor in the quorum sensing network of Pseudomonas aeruginosa [PDF]

, 2006
Certain members of the fluorescent pseudomonads produce and secrete phenazines. These heterocyclic, redox-active compounds are toxic to competing organisms, and the cause of these antibiotic effects has been the focus of intense research efforts.

Selectivity and Efficiency of Conductive Molecularly Imprinted Polymer (c-MIP) Based on 5-Phenyl-Dipyrromethane and 5-Phenol-Dipyrromethane for Quorum Sensing Precursors Detection

Chemosensors, 2017
Functional polymers that selectively recognize target compounds are developed by imprinting polymerization. In the present paper, two different dipyrromethanes, 5-phenol-dipyrromethane (5-pOH-DP) and 5-phenyl-dipyrromethane (5-ph-DP), are synthetized and

Labrenzia sp. BM1: A Quorum Quenching Bacterium That Degrades N-acyl Homoserine Lactones via Lactonase Activity

Sensors, 2014
We report the degradation of quorum sensing N-acylhomoserine lactone molecules by a bacterium isolated from a Malaysian marine water sample. MALDI-TOF and phylogenetic analysis indicated this isolate BM1 clustered closely to Labrenzia sp.

Mechanisms of Gui Zhi Fu Ling Formula in Liver Fibrosis: Metabolomics and Gut Microbiota Analysis

eFood, Volume 7, Issue 3, June 2026.
Our study was based on the efficacy of the phenotype in an animal model and used multi‐omics to explore the mechanism of action of the compound. We found that Gui Zhi Fu Ling Formula may ameliorate hepatic fibrosis potentially associated with increased hepatic EPA and the expression of gut Pseudomonas.
