What benefits of Aureobasidium pullulans have been cited in the scientific literature?
Aureobasidium pullulans is cited in peer-reviewed research as a biocontrol organism with a range of potential agricultural applications. Studies report a 30–60% reduction in Monilinia laxa post-harvest rot on cherry under pre-harvest field conditions, and the species has been registered as a commercial biocontrol product for plant protection — two data points growers and formulators searching for 'Aureobasidium pullulans biocontrol efficacy' will find relevant.
The literature documents preventative activity against Botrytis cinerea gray mold on ripe grape berries (highest control at 25°C) and a 45% reduction in gray mold on harvested strawberries alongside a 100% increase in shelf life when A. pullulans is bumblebee-vectored during flowering. These are literature-reported findings, not approved label claims or regulatory endorsements.
Strain-level variation matters when evaluating Aureobasidium pullulans plant growth promotion claims. Strain YA05 reportedly synthesizes indole-3-acetic acid (IAA) and inhibits phytopathogenic fungi including Phytophthora infestans and Fusarium graminearum. Strain JYC104, tested separately, showed weak phosphate-solubilizing capacity and no plant growth-promoting ability — a direct caution against generalizing across strains.
The literature also cites A. pullulans in mitigating drought stress in Abies koreana seedlings through rhizosphere microbiome modulation, reducing phytopathogenic Fusarium levels and increasing beneficial microbial abundance. Researchers and product developers assessing what the research says about Aureobasidium pullulans should treat all cited benefits as strain- and condition-specific.
