| isolation of epiphytic yeasts with potential for biocontrol of aspergillus carbonarius and a. niger on grape. | antagonistic yeasts were isolated from the epiphytic flora associated with grape berries cv. negroamaro and identified at species level using molecular methods. a total of 144 yeast isolates were tested in a preliminary screening on agar to select isolates showing a killer activity against aspergillus carbonarius and a. niger, the main species responsible for the accumulation of ochratoxin a in grape. twenty-eight yeast isolates were selected for their inhibitory effects on the above fungal spec ... | 2006 | 16443300 |
