In vivo and in vitro experiments were conducted to determine whether P in a low-phytate corn (LPC) containing the lpa 1-1 allele is more available than P in a near-isogenic wild-type corn hybrid (NC). The LPC was analyzed to contain 0.18% nonphytate P and 0.26% total P (TP), whereas NC contained 0.05% nonphytate P and 0.25% TP. For these studies, nonphytate P was considered to be available P (A...

A study was conducted to investigate the effects of physically effective neutral detergent fiber (peNDF) content of dairy cow diets containing corn silage as the sole forage on intake, chewing, ruminal pH, microbial protein synthesis, digestibility, and milk production. A second objective was to compare current methods of measuring peNDF to determine the most suitable approach for use in ration...

The question whether pyruvic acid holds a key position as an intermediate in the butanol-acetone fermentation by Clostridium acetobutylicum (Weizmann) similar to that in the alcoholic fermentation by yeast and in glycolysis by muscle has, so far, not received a decisive answer. This is mainly due to the inconsistent results obtained by different workers in this field. As in the case of corn-mea...

Hydrogenated coconut oil and its component fatty acids appear to be the most striking examples of dietary lipid inhibitors reported for the carcinogen p-dimethylaminoazobenzene. When these substances were fed to rats as the sole sources of lipid in synthetic diets containing the azo dye very few liver tumors, if any, appeared by 6 months (3, 4). If," however, a fat such as corn oil was fed inst...

Management systems influence soil quality over time. A study was carried out on Vanmeter farm of the Ohio State University South Centers at Piketon Ohio, USA to evaluate the impact of crop rotations on soil quality from 2002 to 2007. The crop rotations comprised of continuous corn (CC), corn-soybean (CS) and corn–soybean-wheat-cowpea (CSW). Ten soil cores were collected at 0-7.5, 7.5-15, 15-22....

In 1938 Schantz, Elvehjem, and Hart (1) reported that rats, calves, and pigs which received liquid skim milk as their sole diet excreted a considerable amount of galactose in the urine. No such excretion occurred when whole milk was fed. In studies with the rat it was found that the addition of 3 to 4 per cent of fat to the skim milk completely prevented the urinary loss of galactose, and furth...

This study reports an industrially applicable non-sterile xylitol fermentation process to produce xylitol from a low-cost feedstock like corn cob hydrolysate as pentose source without any detoxification. Different immobilization matrices/mediums (alginate, polyvinyl alcohol, agarose gel, polyacrylamide, gelatin, and κ-carrageenan) were studied to immobilize Candida tropicalis NCIM 3123 cells fo...

Cyclodextrin glucanotransferase (CGTase, EC 2.4.1.19) production using new alkaliphile Microbacterium terrae KNR 9 was investigated by submerged fermentation. Statistical screening for components belonging to different categories, namely, soluble and raw starches as carbon sources, complex organic and inorganic nitrogen sources, minerals, a buffering agent, and a surfactant, has been carried ou...
