This work aimed to evaluate the effect of sugar cane molasses and glycerol on glutathione (GSH) fermentation by Saccharomyces cerevisiae ATCC 7754 in flask culture using response surface methodology. Under optimized conditions (80 g/L of molasses and 60 g/L of glycerol), the highest GSH and biomass concentration achieved were 119.6 mg/L and 25.3 g/L, respectively. Further studies done in 5 L bi...

In the course of our work into the use of cane by-products, we have studied the isolation and structural determination of bioactive compounds in sugarcane molasses. In this study, three stereo isomers of syringyl glycerol 3'-O-beta-D-glucopyranoside, three stereo isomers of guaiacyl glycerol 3'-O-beta-D-glucopyranoside, a syringyl glycerol 2'-O-beta-D-glucopyranoside, tachioside and a 2,3-dihyd...

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...

Sugar cane molasses has proved cohesive and excellent performance on soil aggregates (fine particles). However, the microstructure of consolidated by is not yet subjected to research. The analysis results sample without (0%) samples at 8%, 12%, 16% show that acts structure clayey fine developing its airy matrix type (sample a qualified type, more solid. Consolidated molasses). We also observe p...

Ethanol is a renewable resource of energy and is potentially cleaner alternative to fossil fuels. Production of ethanol is growing day by day at a great extent for its versatile application and demand. During recent years, production of ethanol by fermentation on a large scale has been of considerable interest to meet to increased demand. Fermentation is a biological process in which sugars suc...

Information was sought on the cause, effects, and control of dextran in sugar manufacture in Jamaica. Storage experiments on manually harvested, burnt, whole-stalk cane revealed that Leuconostoc mesenteroides was the predominant spoilage organism. Its growth was accompanied by significant increases in dextran content and juice viscosity. However, these parameters. did not increase linearly with...
