The effects of aeration and agitation in fermentation processes of Vitamin C were studied with three fermenters of 12 l, 3.4m~3 and 50m~3,The results obtained were as follows: 1. It is found that the rheological characteristics and some physical properties of the mixture in the Vitamin C fermenter process are close to those possessed by water, they varied only slightly during the fermentation process.
A cellular automata model for simulating fed-batch penicillin fermentation process
The concentration of eight kinds of catechins in solution decreased by 29.6-47.6%, respectively; some catechins were absorbed and accumulated by yeast cells, but the amount in the cells was very low during the fermentation process.
The two-stage fermentation process that we developed provided a further two- to threefold increase in the production of carbohydrases.
This attractive feature of this technology has contributed to the implementation of several plants in fermentation process for the production of organic and amino acids.
The fermentation process has been tested in a fixed-bed and a gas-lift arrangement.
The transition rules of CAPFM are designed based on mechanical and structural kinetic models of penicillin batch-fed fermentation processes.
The simulation experimental results show that CAPFM replicates the evolutionary behavior of penicillin batch-fed fermentation processes described by the structured penicillin production kinetic model accordingly.
A comparative molecular genetic study of cultured Saccharomyces strains isolated from the surface of berries and various fermentation processes showed that baker's yeast and black-currant isolates contain not only Saccharomyces cerevisiae but also S.
The impact of dose-dependent caloric salvage by microbial fermentation processes in the lower gut and the extent of renal excretion for the overall energetic availability of the alternative bulk sweetener Palatinit were investigated in rats.
On-line monitoring of fermentation processes by ultrafiltration and column liquid chromatography
The possibility of quantitative determination of specific components in mixtures of ethanol samples with various isotope compositions (chemical synthesis and alcohol fermentation of raw material from C3 or C4 plants) was shown.
A positive effect of iron on the methanogenic fermentation of fats and their degradation products-long-chain fatty acids-in aqueous media was demonstrated.
Carbon dioxide-monitored solid-state fermentation of oat straw by the coculture of filamentous fungi was successfully performed in an aerated bench-scale reactor.
Specific Features of Fermentation of D-Xylose and D-Glucose by Xylose-Assimilating Yeasts
After fermentation of whey with selected yeast strains at 30°C for 2-3 days, the ethanol concentration was 4-5%.
