A new local strain of S. cerevisiae F-514, for ethanol production during hot summer season, using Egyptian sugar cane molasses was applied in Egyptian distillery factory. The inouluum was propagated through 300 L, 3 m(3), and 12 m(3) fermenters charged with diluted sugar cane molasses containing 4%-5% sugars. The yeast was applied in fermentation vessels 65 m(3) working volume to study the vary...

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...

The South African sugar industry can be regarded as mainly a diffusion industry with 76% of all cane now handled by diffusers. With the conversion from milling to diffusion, concerns were expressed that higher temperatures, imbibition levels and improved extraction in itselfwould result in various processing difficulties. Among these were expected clarification problems associated with the extr...

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 most common pathogenic agent in sunflower is sclerotinia sclerotiorum which in some cases can be successfully controlled by some antagonistic bacteria. environmental factors such as carbon sources are effective on antagonistic strains but application of pure carbohydrates for mass production of these agents is expensive. so in most cases agricultural and industrial residues (such as molasse...
