Optimization of HFDS Production from Date Syrup (RESEARCH NOTE)
Fructose is utilized as a common sweetener in many food industries. Today, a large amount of HFCS (high fructose corn syrup, an equilibrium mixture of glucose and fructose) is produced by glucose isomerase, immobilized enzymes from corn starch. There are a lot of date palms in Iran. Date is a favorable source of carbohydrates, and a suitable source for HFDS (high fructose date syrup) production...
متن کاملDate Wastes as Substrate for the Production of a-Amylase and Invertase
Background: In Algeria the date wastes production is estimated at least 85.000 tones. Date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced. Objective: The aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. Materia...
متن کاملKinetics of Invertase Production by Saccharomyces Cerevisiae in Batch Culture
The present study is concerned with the improved invertase production by Saccharomyces cerevisiae on kinetic basis. The wild-culture (IIB-1) and putative mutant (NA6) of S. cerevisiae were compared on time course basis when grown in batch culture. The values for Yx/s, Yp/s and Yp/x with urea were significantly improved (p≤0.05) over the control (peptone+yeast extract) as well as peptone supplem...
متن کاملInvertase Production from a Hyperproducing Saccharomyces Cerevisiae Strain Isolated from Dates
Invertase production by wild cultures of Saccharomyces cerevisiae isolated from dates available in local market is reported. Five hyperproducing yeast strains (>100 fold higher invertase activity) were kinetically analyzed for invertase production. Saccharomyces cerevisiae strain GCAII was found to be a better invertase yielding strain among all other isolates. The values of Qp and Yp/s for GCA...
متن کاملUtilization of date syrup as a substrate for carotenoid production by Rhodotorula glutinis
The potential use of date syrup, for the production of carotenoids by Rhodotorula glutinisin batch fermentation process, was investigated during 7 days. The results revealed that carbon (glucose or date syrup) and nitrogen sources [yeast extract, (NH4)2SO4 and NH4NO3] had a significant influence on biomass and carotenoid production. Maximum yield of total carotenoid production (7.94 mg/L) with ...
