Abstract
En 中文
The aim of the study was the fungal production of fructooligosaccharides from solid-state fermentation of different agro-industrial wastes (sugar cane bagasse, coffee husk, pineapple peel, prickle pear peel and banana peel) enriched with maguey sap. An exploratory statistical design with a factorial arrangement (2(3)) was used to identify some parameters that are directly related to the production of FOS. The production was optimized and evaluated through fermentation kinetics in order to determine the time of maximum FOS production. Among the evaluated materials, sugar cane bagasse was the most promising substrate suited for the FOS production reaching a concentration of 7.64 g of FOS per liter of culture medium based on the initial sucrose concentration (21 g/L), a high Yp/s = 0.45 based on sucrose consumed was observed. The results showed that use of sugar cane bagasse enriched with aguamiel is the most economical and excellent alternative source for the FOS production by Aspergillus oryzae DIA-MF.
