| Popis: | Blastospores of the entomopathogenic fungus Paecilomyces fumosoroseus were formulated with 10% lactose/1% bovine serum albumin (BSA) or various compositions of Fantesk™, a starch–oil composite prepared by jet-cooking an aqueous dispersion of starch and oil. Storage stability studies with wet blastospore formulations showed that maximum blastospore survival was achieved during low-temperature storage at −20°C with lactose/BSA formulations or starch–oil formulations supplemented with sucrose, zein protein, and whole milk. Under conditions of wet storage at −20°C, the addition of whole milk to starch–oil formulations significantly improved blastospore stability while the addition of sucrose or zein protein had no effect. In freeze-drying studies, no significant differences were seen in blastospore desiccation tolerance or in stability during storage at either 4 or −20°C when blastospores of P. fumosoroseus were formulated with lactose/BSA or starch–oil formulations with sucrose, zein protein, and wh... |
