Effects of corn fiber residue (5 g/day for 10 days) on fecal weight, moisture, pH, fecal flora, ammonia content, and on the activities of beta-glucuronidase and beta-glucosidase were investigated in six healthy subjects. Corn fiber residue was remnant of hemicellulose extraction from corn fiber by calcium hydroxide. Fecal weight showed a tendency to increase, and fecal pH did not change during ...

A recent study of the ability of chloroform in drinking water to produce cancer reported that male Osborne-Mendel rats developed renal tumors, but that female B6C3F1 mice failed to develop hepatocellular carcinomas. The results obtained in the male Osborne-Mendel rats were comparable to those observed in an earlier study sponsored by the National Cancer Institute (NCI). On the other hand, the l...

Based on the biological activity of arachidonic acid metabolites, we hypothesized that alterations in the consumption of linoleic acid, the precursor to arachidonic acid, would result in a modification in tumor development when fed during the tumor promotion stage of the mouse skin initiation-promotion model. The effects of seven different levels of dietary linoleic acid (LA), supplied as corn ...

Polyhydroxyalkanoates (PHA) and α-amylase (α-1,4 glucan-4-glucanohydrolase, E.C. 3.2.1.1) were co-produced by Bacillus sp. CFR-67 using unhydrolysed corn starch as a substrate. Bacterial growth and polymer production were enhanced with the supplementation of hydrolysates of wheat bran (WBH) or rice bran (RBH) individually or in combination (5-20 g L(-1), based on weight of soluble substrates-SS...

Narrow-row soybean [Glycine max (L.) Merr.] production in corn [Zea mays L.]–soybean rotations results in various distances of soybean rows from previous corn rows, yet little is known about soybean responses to proximity to prior corn rows in no-till systems. The objective of this study was to evaluate the impacts of preceding corn rows on potassium (K) nutrition and yield of subsequent no-til...

Corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] rotations are common production systems across the midwestern United States. However, the interactive effect of crop rotation, tillage, and nematicide seed treatments on the yield of both crops in the rotation system is not well understood. Field trials were conducted in a long-term crop rotation experiment during 2013 to 2015 to measure y...

Three oxygenated unsaturated fatty acids were investigated to determine whether they were present in seedlings of corn (Zea mays L. cv. NK PX443) and sunflower (Helianthus annuus L. cv. Sundak). The three compounds, 13-hydroxy-12-oxo-cis-9-octadecenoic acid (I), 13-hydroxy-12-oxo-cis,cis-9, 15-octadecadienoic acid (II), and 12-oxo-cis,cis-10, 15-phy-todienoic acid (III), were detected and estim...

Greenhouse experiments were conducted to evaluate the effect of Nod factor Nod Bj-V (C18:1, MeFuc) of Badyrhizobium japonicum on the growth of soybean and corn. Three-day-old seedlings of soybean and corn were grown in hydroponic solutions containing four concentrations (0, 10(-7), 10(-9) or 10(-11) M) of Nod factor. After 7 d of treatment, Nod factor enhanced soybean and corn biomass. Nod fact...

Beef finishing and dairy lactation experiments were conducted to evaluate the nutritional value of distillers grains (DG) from sorghum or corn fermentation, in both wet (35.4% DM) and dry (92.2% DM) form (dairy trial only). In the finishing experiment, 60 yearling steers were used in a completely randomized design with three diets that were fed for 127 d: 1) control diet with 86% (DM basis) dry...
