摘要

The effects of drying methods (freeze-, spray-, and fluid bed-drying) on viability of Penicilliumfrequentans conidia were compared. Viability, estimated by germination of fluid bed- and freezedried conidia, was similar to that of fresh conidia. Skimmed milk alone, or in combination withother protectants, was added to conidia before freeze-drying. After the freeze-drying process, allprotectants used, except glycerol improved conidial viability. Freeze-dried P. frequentans conidiadid not maintain viability after 30 days of storage at room temperature, while conidia dried by fluidbed-drying showed 28% viability following 180 days after drying. This work also demonstrated arelationship between conidial viability after 1 year of storage at room temperature, moisturecontent after fluid bed-drying and initial weight of sample. Conidial moisture contents must bereduced to 5-15% for optimal storage at room temperature. E frequentans conidia dried by fluidbed-drying were as effective as fresh conidia in controlling brown rot of peaches.
