The aim of this work was to evaluate the capability of corn steep liquor being a low cost substrate on the recombinant protein production by cultivating recombinant Escherichia coli and increasing the production of hyperthermophilic esterase (HE). The effect of corn steep liquor, mineral salt and trace metals on hyperthermophilic esterase production was investigated by means of a five-level thr...

Currently short-chain polyols such as ethanediol, propanediol, and butanediol are produced either from the petroleum feedstock or from the starch-based food crop feedstock. In this study, a combinational process of enzymatic hydrolysis with catalytic hydrogenolysis for short-chain polyols production using corn stover as feedstock was developed. The enzymatic hydrolysis of the pretreated corn st...

NCH 4 Revised April 1993 Despite signifi cant progress made over the years, disease is still a major factor limiting corn production in the U.S. Estimates of annual yield losses in corn due to disease range from 7 to 20 percent nationally (Shurtleff, 1980). Using a 12 percent average, that’s nearly 1 billion bushels. Without the development of new hybrids, the losses would easily be more than d...

The origin of U.S. Corn Belt corn (Zea mays L.), heterotic groups, and heterotic patterns becomes less obvious with more cycles of breeding. Heterosis is poorly understood; simple curiosity cries out for more information. I endeavor to shed light on the effect of adaptedness and heterosis on U.S. Corn Belt corn. I relate pertinent happenings in the phenomenal increase in U.S. corn production. I...

An experiment employing a factorial arrangement of three levels (0, 8 and 16%) of canola meal (CM), two levels (0.15 and 0.25%) of nonphytate phosphorus (NPP), and two levels (0 and 450 unit/kg; as fed basis) of microbial phytase was conducted using 216 Hy-Line W36 laying hens from 39 to 47 weeks of age. The birds receiving CM consumed more (P < 0.05) feed than birds receiving corn-soybean meal...

Corn harvested as grain is a relatively new crop for the province of New Brunswick. The recent availability of local corn has the potential to improve the sustainability of the dairy industry in New Brunswick, but there is debate within the industry concerning the value and best use of the grain. This experiment was conducted to assess the feeding value of locally-produced corn grain stored as ...

Y variability for a given crop differs geographically and depends on soil type and quality, climate, and the use of irrigation. Yield variability is often measured by an indicator known as the “coefficient of variation,” which measures randomness relative to the mean (or average) value in the yield series. Using this measure, variability in corn yields, for example, ranges from about 0.2 to abo...

The objective of this study was to compare effects of dietary polyunsaturated fatty acid supplementation (corn oil or fish oil) on selected immune responses in normal horses. Two groups of horses (n = 5) were randomly assigned a dietary supplement with either 3.0% corn oil or fish oil for a period of 14 weeks. Plasma fatty acid profiles were monitored to ensure uptake of dietary fatty acids. Ce...

The corn and soybean markets have been bidding for acreage due to a bullish final crop report for 2006. With biofuels creating new markets for corn and soybeans, this demand-driven market may continue to provide marketing opportunities. Currently, the major decision facing producers is determining the enterprise mix for 2007. This memo compares the Returns over Variable Costs for corn and cotto...
