Un método de adsorción utilizando la resina Dowex™Marathon™ WBA ha sido desarrollado con el fin evaluar larecuperación ácido cítrico producido por fermentación sumergida. Para determinar viabilidad este separación, fue evaluada a diferentes condiciones temperatura (30 – 70 °C) y pH (1.5 6.5). Los resultadosmostraron que bajo, se mejora cítrico, través cual, recupera 85% del obtiene una pureza 9...

Chromium-VI would impose detrimental effects morphological, physiological, and metabolic in plants. This study aimed to research the impact of citric acid (0, 2.5 and 5 mM), on different the morphological and physiological characteristics of garden cress exposed to chromium-VI stress (0, 1, and 10 mM). Results showed that some growth parameters, chlorophyll, carotenoids, and DPPH activity decre...

In fermented products containing Bifidobacteria, factors such as organic acid concentration and b-galactosidase activity are important in the development of flavor and texture of final products. Both the process conditions and medium components have significant effects on fluctuation of such factors. The effects of whey permeate powder and yeast extract concentrations, as nitrogen sources was i...

New in vitro anti-diabetes makgeolli was produced from rice by adding various quantities of Laminaria japonica, and the fermentation characteristics of the L. japonica makgeolli during the fermentation process were investigated. The contents of alcohol and reducing sugar, and viable count of yeast, of L. japonica makgeolli were not significantly changed when the proportion of L. japonica was in...

BACKGROUND Aspergillus niger was selected as a host for producing itaconic acid due to its versatile and tolerant character in various growth environments, and its extremely high capacity of accumulating the precursor of itaconic acid: citric acid. Expressing the CAD gene from Aspergillus terreus opened the metabolic pathway towards itaconic acid in A. niger. In order to increase the production...

Grass, clover and alfalfa are used for production of fodder pellets. In the green crop drying factories in the northern countries the drying is combined with pressing of the green crops resulting in production of large volumes of plant juices, green and brown juice. In order to get rid of these enormous amounts of plant juice, representing an environmental threat, it is our aim to convert the s...

The aim of this study was to investigate the effect of sodium dodecyl sulfate (SDS), citric acid, and hydrogen peroxide (H2O2), alone or in combination, on reducing the population of four foodborne pathogens, including Escherichia coli, Listeria monocytogenes, Salmonella typhimurium, and Staphylococcus aureus on eggshells. In each series of tests, eight fresh eggs were inoculated with each bact...
