Secado en lecho fluido de un prototipo granulado a base de la levadura con potencial probiótico Meyerozyma guilliermondii: selección de parámetros de proceso y protector de secado

Abstract

Meyerozyma guilliermondii strain Lv196 has been identified as a native Colombian yeast with a high probiotic potential increasing rumen microbial e ciency at in vitro assays when a ruminant digestion system is simulated. Often, these types of products are supplied in a granulated form to facilitate its dosage to ruminants as cows, sheep, among others. To produce granulated bioproducts based on microorganisms, it is required to select suitable drying conditions, protectants and the adequate drying operation, decisive factors to guarantee cell viability and stability during storage. Most granulated products are dried through fluidized bed drying process reducing investment and maintenance costs, and improving mass and heat transfer decreasing operation time and the risk of product overheating. Therefore, in this work a selec... Ver más...
