Description

Tolaasin CAS NO 132541-40-3 is a lipodepsipeptide toxin primarily produced by certain strains of *Pseudomonas tolaasii*. This compound is of significant interest due to its potent biological activity, specifically its role in causing brown blotch disease in cultivated mushrooms. Industries and research institutions focused on plant pathology, agricultural biotechnology, and microbial ecology require high-purity Tolaasin for studies on host-pathogen interactions, disease mechanism elucidation, and the development of targeted biocontrol strategies.

Application

• Phytopathology Research: Fundamental studies on the mechanism of brown blotch disease in edible mushrooms.
• Agricultural Biotechnology: Screening for and development of resistant mushroom strains or effective antifungal agents.
• Microbial Ecology: Investigation of bacterial virulence factors and inter-microbial competition in agricultural settings.
• Biocontrol Agent Development: Used as a reference toxin to evaluate the efficacy of potential biocontrol bacteria or compounds.
• Enzyme & Membrane Studies: Serves as a tool compound for studying pore-forming toxins and their interaction with biological membranes.
• Diagnostic Kit Development: Potential use as an antigen or standard in diagnostic assays for detecting pathogenic *P. tolaasii* strains.
