Pseudomonas tolaasii

Pseudomonas tolaasii is a species of Gram-negative soil bacteria that is the causal agent of bacterial blotch on cultivated mushrooms (Agaricus bisporus).[1] It is known to produce a toxin, called tolaasin, which is responsible for the brown blotches associated with the disease.[2] It also demonstrates hemolytic activity, causing lysis of erythrocytes.[3] Based on 16S rRNA analysis, P. tolaasii has been placed in the P. fluorescens group.[4]
