title: Production, formulation and antagonistic activity of the biocontrol like-yeast Aureobasidium pullulans against Penicillium expansum.
abstract: Aureobasidium pullulans (de Bary) Arnaud (Ach 1-1) was grown in a glucose fed-batch fermentor to 106 g dry wt l(-1) in 48 h. The cells were dried in a fluidized bed dryer with a final viability of 62%. After 7 months at 4 degrees C, the viability was 28% of the initial value (= 2.3 x 10(10 )c.f.u. g(-1) dry matter). A protection level of 89% was achieved with the biomass preparation at 1 x 10(8 )c.f.u. ml(-1) after 28 and 7 days for apples stored respectively at 5 and 25 degrees C against Penicillium expansum. Our process is suitable to produce large quantities of the strain Ach 1-1 as biological control agent for apple preservation.
