Kinetics of the continuous alcoholic fermentation of blackstrap molasses.
The very important problems concerning fermentation kinetics have only recently received some attention (Calam et al., 1951; Gaden, 1955a, b, 1956; Borzani, 1957; Kosin, 1957). In the particular case of continuous alcoholic fermentation, a great number of papers have been published (Alzola, 1940, 1945; Bilford et al., 1942; Owen, 1948; Asai et al., 1952, 1953; Mariller et al., 1952; Borzani, 19...
متن کاملInvestigation of yeast performances in the fermentation of beet and cane molasses to ethanol production
___________________________________________________________________________________________ Abstract In commercial ethanol production producers often use sugarcane or sugar beet molasses as raw material due to their abundance and low costs. The most employed microorganism used for fermentation is Saccharomyces cerevisiae yeast due to its ability to hydrolyze sucrose from cane or beet molasses i...
متن کاملPenicillin and tetracycline as contamination control agents in alcoholic fermentation of sugar cane molasses.
Several papers have been published to show the use of antibiotics as inhibitors of foreign microorganiisms in industrial fermentations (Strandskov and Bockelmann, 1953; Day et al., 1954; Borzani and Aquarone, 1957; Aquarone, 1958; Falcone, 1958; Torloni et al., 1958; Falcone, 1959; Aquarone, 1959) to assure high yields and/or good quality products. The favorable influence of penicillin as a con...
متن کاملEffect of Storage Temperature and Light on the Freeze-Dried Amino Acids from Sugar Beet and Sugar Cane Molasses
Molasses is a significant by-product of sugar beet or sugar cane refining industry. In this work, the effects of storage temperature and packaging on the contents of free amino acids (AAs) in sugar beet and sugar cane molasses after freeze drying were inquired. The effect of different variables such as, temperature (4 and 25˚C) and light (Metallized polypropylene container and Normal polypropyl...
متن کاملFermentation of molasses by Zymomonas mobilis: effects of temperature and sugar concentration on ethanol production.
Fermentations utilizing strains of Zymomonas mobilis, in place of the traditional yeasts, have been proposed due their ethanol yields being close to theoretical. Ethanol production from sugar cane molasses was analyzed under different culture conditions using Z. mobilis in batch fermentation. The total reducing sugars (TRS) concentrations in the molasses, temperature, agitation and culture time...
