BACKGROUND Conventional corn dry-grind ethanol production process requires exogenous alpha and glucoamylases enzymes to breakdown starch into glucose, which is fermented to ethanol by yeast. This study evaluates the potential use of new genetically engineered corn and yeast, which can eliminate or minimize the use of these external enzymes, improve the economics and process efficiencies, and si...

There is currently much ongoing research and interest for developing new processing technologies to produce corn distillers dried grains with solubles (DDGS). The current study evaluated a high protein (HP) DDGS and a dehydrated corn germ meal which are the products that can be produced by a modifi ed dry milling process. To evaluate the nutritional characteristics of these products, a chick ex...

J. Econ.Entomol. 79: 1658-1661 (1986) ABSTRACT Processingsweet corn harvested from commercial fields in western New York was graded for insect injury and presence of larvae of European corn borer, Ostrinia nubilalts (Hubner); fall armyworm, Spodoptera !rugiperda (]. E. Smith); and corn earworm, Heliothts zea (Boddie), during 1982 and 1983. In both years, boring injury caused by O. nubilalts was...

Helicoverpa zea Boddie (Lepidoptera: Noctuidae), the corn earworm, is a key pest of sweet corn (Poales: Poaceae) in many parts of the United States. Integrated pest management (IPM) practices for H. zea in fresh and processing sweet corn use pheromone trap counts of male moths for management decisions. In this study, we examined whether sweet corn could be protected more effectively if insectic...

Laboratory tests were conducted to establish the relative toxicity of Bacillus thuringiensis (Bt) toxins and pollen from Bt corn to monarch larvae. Toxins tested included Cry1Ab, Cry1Ac, Cry9C, and Cry1F. Three methods were used: (i) purified toxins incorporated into artificial diet, (ii) pollen collected from Bt corn hybrids applied directly to milkweed leaf discs, and (iii) Bt pollen contamin...

Corn, Zea mays L., is the cereal with the highest production rate around the world, with an estimated production that exceeded 1021 million tons in 2014 (1). Corn is also the staple food for over 900 million people located in sub-Saharan Africa, South Asia, and Latin America. Around 600 million people are corn dependent, including 120 million malnourished children (2). As an example, the averag...
