Synthesis of a 2,4,6,8,10-dodecapentanoic acid thioester as a substrate for biosynthesis of heat stable antifungal factor (HSAF)

RSC Advances, 2015
The N -acetylcystamine thioester of dodecapentaenoic acid is synthesized. The thioester is investigated as a biosynthetic substrate and was not incorporated in the observed products.

Optimization of culture conditions for promoting heat-stable antifungal factor production level in Lysobacter enzymogenes

FEMS Microbiology Letters, 2019
ABSTRACT Heat-stable antifungal factor (HSAF), which was first isolated from Lysobacter enzymogenes, exhibits inhibitory activities against a wide range of pathogens; however, a low level of HSAF was obtained from L. enzymogenes cultured in 0.1 × tryptic soy broth (TSB), an amount that does not satisfy HSAF application in disease control.

Lysobacter enzymogenes prevents Phytophthora infection by inhibiting pathogen growth and eliciting plant immune responses

Frontiers in Plant Science, 2023
The Phytophthora pathogen causes enormous damage to important agricultural plants. This group of filamentous pathogens is phylogenetically distant from fungi, making them difficult to control by most chemical fungicides. Lysobacter enzymogenes OH11 (OH11)

Clp is a “busy” transcription factor in the bacterial warrior, Lysobacter enzymogenes

Computational and Structural Biotechnology Journal, 2021
Cyclic AMP receptor protein (CRP) is a well-characterized group of global transcription factors in bacteria. They are known to regulate numerous cellular processes by binding DNA and/or cAMP (a ligand called bacterial second messenger) to control target ...

Heat-Stable Antifungal Factor (HSAF) Biosynthesis in Lysobacter enzymogenes Is Controlled by the Interplay of Two Transcription Factors and a Diffusible Molecule [PDF]

Applied and Environmental Microbiology, 2018
ABSTRACT Lysobacter enzymogenes is a Gram-negative, environmentally ubiquitous bacterium that produces a secondary metabolite, called heat-stable antifungal factor (HSAF), as an antifungal factor against plant and animal fungal pathogens.

Control of Wheat Fusarium Head Blight by Heat-Stable Antifungal Factor (HSAF) from Lysobacter enzymogenes [PDF]

Plant Disease, 2019
Heat-stable antifungal factor (HSAF), which belongs to the polycyclic tetramate macrolactam family, was isolated from Lysobacter enzymogenes fermentations and exhibited inhibitory activities against a wide range of fungal pathogens. In this study, the antifungal activity of HSAF against Fusarium graminearum in vitro and in vivo was investigated.

Loss of Flagella-Related Genes Enables a Nonflagellated, Fungal-Predating Bacterium To Strengthen the Synthesis of an Antifungal Weapon

Microbiology Spectrum, 2023
Loss of flagellar genes causes a nonmotile phenotype. The genus Lysobacter consists of numerous environmentally ubiquitous, nonflagellated bacteria, including Lysobacter enzymogenes, an antifungal bacterium that is beneficial to plants. L.

Control of glucosylceramide production and morphogenesis by the Bar1 ceramide synthase in Fusarium graminearum. [PDF]

PLoS ONE, 2011
The contribution of plasma membrane proteins to the virulence of plant pathogenic fungi is poorly understood. Accordingly, the objective of this study was to characterize the acyl-CoA dependent ceramide synthase Bar1 (previously implicated in plasma ...

LeTetR Positively Regulates 3-Hydroxylation of the Antifungal HSAF and Its Analogs in Lysobacter enzymogenes OH11

Molecules, 2020
The biocontrol agent Lysobacter enzymogenes OH11 produces several structurally distinct antibiotic compounds, including the antifungal HSAF (Heat Stable Antifungal Factor) and alteramides, along with their 3-dehydroxyl precursors (3-deOH).

Characterisation of the Antibiotic Profile of Lysobacter capsici AZ78, an Effective Biological Control Agent of Plant Pathogenic Microorganisms

Microorganisms, 2021
Determining the mode of action of microbial biocontrol agents plays a key role in their development and registration as commercial biopesticides. The biocontrol rhizobacterium Lysobacter capsici AZ78 (AZ78) is able to inhibit a vast array of plant ...
