Abstract
Meyerozyma guilliermondii is yeast considered as a biocontrol agent for its large spectrum of plant pathogens. After the molecular identification of this yeast, we evaluated the antifungal activity in vitro against Botrytis cinerea (36.8%) and Fusarium oxysporum radis lycopersicum (FORL) (40.2%). Furthermore, the application of M. guilliermondii on the hydroponic medium might promote planting by directly inducing growth or indirectly by inducing defense. The treatments by M. guilliermondii and the culture filtrate (CF) increase the length of the roots, shoots length, and dry matter over untreated control. Besides, induced biochemical defensive enzymes (peroxidase, β-1,3-glucanase, and phenolic compounds) were measured after 3, 6, and 9 days posttreatments, all of which were correlated with the induced defense. This result reported that M. guilliermondii and the culture filtrate promote plant growth and induce the production of defense enzymes.
