The present investigation deals with the kinetics of submerged citric acid fermentation by Aspergillus niger using blackstrap molasses as the basal fermentation media. A laboratory scale stirred fermentor of 15-L capacity having working volume of 9-L was used for cultivation process and nutritional analysis. Among the 10 stock cultures of Aspergillus niger, the strain GCBT7 was found to enhance...

In recent years, the new trend is towards bio-fuel. One of these biofuels is ethanol (ethyl alcohol), which could be produced economically by the controlled fermentation of biomasses. The results of the alcoholic fermentation of beet sugar molasses and wheat milling residues (Akalona) were fed into a computer program. The kinetic parameters for these fermentation reactions were determined. Thes...

Background The NYD medium (glucose, meat extract, yeast extract and peptone) is used for biomass production of some bacteria species that promote plant species growth [1-3]. The main carbon source present in this medium is the glucose that contributes a percentage of 25% to the medium price. An alternative to obtain a more accessible price for the medium is to replace the glucose by sources of ...

The kinetics of alcoholic fermentation was evaluated using the following substrates: molasses, urea, and diamine phosphate (MUDP); molasses and guava seed flour (MGSF); and molasses and dry mycelium of Aspergillus niger (MMAN). The fermentations were done using Saccharomyces cerevisiae under anaerobic conditions, 32°C, and pH 4.6. For each fermentation substrate the effect of the nitrogen sourc...

This paper applied a simple and cost-benefit method for the production of regenerated bacterial cellulose. The inexpensive production of cellulose with complex media derived from wastewater from food industries such as molasses adds a lot of contaminants to the produced bacterial cellulose, which puts a lot of challenges in cellulose purification. Therefore, the present study aimed...

Introduction: The purpose of this study was formulation and preparation of a proper culture medium for Saccharomyces cerevisiae var. boulardii with molasses and animal serum. Methods: A fully-crossed factorial design contain 5%, 10% and 20% of molasses (M) with 0, 1% and 5% animal serum (S) was used in this study. The pH of all culture medias were adjusted to 5.6 with acetic acid. The seed was ...

The use of native soil bacteria to biodegrade explosives-contaminated soil under co-metabolic conditions has been demonstrated. The addition of food-grade surfactants could improve the process by enhancing the rates of explosives desorption from soil, thereby increasing the bioavailability of explosives for microbial degradation. The objective of this study was to decrease residence time in the...

in order to investigate the effect of diets contained urea and molasses on fattening performance and blood urea nitrogen (bun) density of male lambs, 72 arabic male lambs were used in a completely randomized design with a 3×4 factorial experiment, for 90 days. the experimental diets contained; 0, 0.5, 1 and 1.5% of urea each with 0, 7.5 and 15% of molasses, in isoprotein and isocalaric diets. t...

Recovery of sugars from cane molasses (i.e. the by-product of sugar industries) is of great interest to industry and academia. The prerequisite for refning cane molasses is removal of pigments and suspended solids present in the molasses. In this work, the utilization of membrane separation for clarifcation and decoloration of cane molasses has been examined. Three oper...
