The fertility status of the soil and the standard of fertiliser management can have an important effect on the chemical composition and quality of cane juice. Both nutrient deficiency and nutrient excess can result in below optimum sucrose contents. Excessive potassium uptake may promote cane lodging and high potassium levels in juice can also influence the exhaustibility of final molasses, 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...

The mutant strain of Aspergillus niger NG-110 was evaluated for the present investigation of citric acid production. The cultural conditions optimized during the course of study were pH and K4Fe(CN)6, K2HPO4 and CaCl2 concentrations. Cane-molasses was utilized as the basal fermentation medium. The mutant NG-110 produces maximal amount of citric acid when the pH of the medium was 6. When the con...

The present study is concerned with the production of cephalosporin C by Cephalosporium acremonium C-10. Two culture media were tested for the production of antibiotic. Among these culture media M1 containing sucrose, ammonium acetate, cornstarch, sugar cane molasses, soybean meal, calcium carbonate, calcium sulphate and methyl oleate gave optimum production of cephalosporin C. The cultural con...
