T HREE switchback metabolism studies were conducted to study the effects of replacing corn with 5, 10 and 15% cane molasses. Five percent molasses had no significant effect on any of the parameters studied. At 10 and 15% molasses added at the expense of corn in the basal ration, nitrogen retention and apparent digestibility of dry matter and energy were all significantly improved (P< .05) . The...

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...

The NIRSystems 6500 spectrophotometer has been used to study analytes in bagasse, shredded cane, direct analysis of cane extracts (DAC), mixed juice, molasses and raw sugar. Analytes included pol, brix, dry solids, moisture, sucrose, glucose, fructose, invert, ethanol, colour, ash and starch. Although Near Infra Red (NIR) is a secondary technique, relying on conventional laboratory procedures f...

in this study, the effect of carbon and nitrogen sources, on production of yeast biomass was determined as well as the efficacy of various formulations of candida membranifaciens to decrease blue mold on apple. the media containing sugar cane molasses as carbon sources caused more yeast growth than the media supplemented with permeate powder. yeast extract as nitrogen source produced higher bio...

conclusions our present study shows that sugar beet molasses is a source of plp and l-ser; and hence, suggests the general application of the approach to produce l-trp more economically. results consequently, the potassium phosphate buffer system was considered as the suitably buffered reaction medium. the concentration of l-trp produced in reaction medium was 0.3 mm and 0.12 mm for glucose and...

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...

The present study deals with the pre-treatment of sugar cane molasses for the enhanced production of citric acid by Aspergillus niger NG-4. Different metal complexing agents such as potassium ferrocyanide [K4Fe(CN)6] and ethylene diamine tetra acetic acid (EDTA) were also employed for molasses pre-treatment and the concentrations varied from 50-350 ppm. The maximum production of citric acid (36...

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...
