Corn Distillers Wet Grains
The production of corn‐based ethanol in the United States is dramatically increasing, and consequently, so is the quantity of generated coproducts, all of which are currently fed to livestock. Distillers Wet Grain (DWG) is one of these coproduct feeds. Many studies have investigated the nutritional properties of DWG and the response of livestock (primarily beef and dairy) to inclusion of these ...

the Stokes' equation (4). The anomalous appearance of the curves might suggest that a non-random sample had been selected, but examination of the frequencies of cells appearing in different size ranges reveals a normal distribution indicating that a random sample had been selected. The diameters of cells and the correspondent frequencies are: 3.5-2; 4.0-7; 4.5-10; 5.0-20; 5.5-17; 6.0-8; 6.5-2; ...
متن کاملProduction of citric acid by mutants of Aspergillus niger.
Development of methodology for the recovery of citric acid from the fermented broth involves standardization of the various parameters to achieve maximum performance in terms of recovery and optimum conditions. The present investigation was carried out to study the purification of citric acid from fermented broth by calcium carbonate precipitation and subsequent acid hydrolysis. The parameters ...
متن کاملCitric Acid Production by Aspergillus niger Cultivated on Parkia biglobosa Fruit Pulp
The study was conducted to investigate the potential of Parkia biglobosa fruit pulp as substrate for citric acid production by Aspergillus niger. Reducing sugar was estimated by 3,5-dinitrosalicylic acid and citric acid was estimated spectrophotometrically using pyridine-acetic anhydride methods. The studies revealed that production parameters (pH, inoculum size, substrate concentration, incuba...
متن کاملAconitase and citric acid fermentation by Aspergillus niger.
In view of the often-cited theory that citric acid accumulation is caused by an inhibition of aconitase activity, the equilibrium of the reaction of aconitase was investigated by comparing in vivo steady-state concentrations of citrate and isocitrate in Aspergillus niger grown under various citric acid-producing conditions. With the equilibrium catalyzed by the A. niger enzyme in vitro, similar...
