Spray-Drying to Get Spin-Crossover Materials
Spin-crossover (SCO) triazole-based coordination polymers can be synthesized by micelle techniques, which almost always lead to rod-shaped nanoparticles. In order to notably reach new morphologies, we explore here the potentiality of the spray-drying (SD) method to get SCO materials. Three SCO coordination polymers and a mononuclear complex are investigated. In all cases, the SD method obtains ...
متن کاملEffects of Spray-Drying, Freeze-Drying and Pasteurization on Microbiological Quality and IgG Level of Bovine Colostrum
Background: Nowadays, colostrum has been known as a considerable and valuable by-product of large-scale dairy production in the world. The main objective of this study was to evaluate the effects of pasteurization, spray-drying and freeze-drying methods on bacterial loads and Immunoglobulin G (IgG) level of bovine colostrums. Methods: Colostrum samples were collected from the first milking pos...
متن کاملViability of Bifidobacterium Pseudocatenulatum G4 after spray-Drying and Freeze-Drying
Viability of Bifidobacterium pseudocatenulatum G4 following spray-drying and freeze-drying in skim milk was evaluated. After spray-drying, the strain experienced over 99% loss in viability regardless of the air outlet temperature (75 and 85 °C) and the heat-adaptation temperature (45 and 65 °C, 30 min). The use of heat-adaptation treatment to improve the thermotolerance of this strain was ineff...
متن کاملCirculating-Gas Freeze Drying
WAGMAN, JACK (U.S. Army Biological Laboratories, Frederick, Md.) AND EDWARD J. WENECK. Preservation of bacteria by circulating-gas freeze drying. Appl. Microbiol. 11:244-248. 1963.-Water-washed Serratia marcescens and Escherichia coli were freeze dried in a circulating-gas system at atmospheric pressure. This convective procedure resulted in a substantially higher survival of organisms than cou...
متن کاملFreeze-drying of Aegyptianella pullorum.
Heparinized whole blood, parasitized with Aegyptianella pullorum, was collected from 2 fowls. Buffered lactose peptone (BLP) was added v/v as a stabilizer and the mixture lyophilized in 2 ml aliquots after rapid or slow freezing. At different stages during the freeze-drying process, as well as after lyophilization and reconstitution with 1.8 ml of sterile water, samples were taken and injected ...
