In this study, the cutting force and energy requirement of corn (Zea mays L.) stalk at different internodes (diameter), from bottom to top internode positions for Pionner 2105, Pioner 1570, KWS MAY 75 varieties, were determined. The mean diameter varied between 11.28-19.00 mm bottom. Also, cob breakout requirements determined these varieties. According test results, varieties found statisticall...

Physical and mechanical properties of food crops gain importance during design threshing shilling machine. In Egypt, Corn is emerging as the third most important crop after rice wheat, it has significance a source large number industrial products besides its use human animal feed. Third largest cereal produced in world with trend rising production Egypt. The normal area for Egypt was hectares a...

The fermentability of a corn cob, acid-hydrolysed hemicellulose by Pichia stipitis was considerably improved by pre-treatment with Ca(OH)2. The total sugars utilized and ethanol yield for the untreated hydrolysate were 18% and 0.21 g/g, respectively, compared with 82% and 0.32 g/g respectively for the treated material. Adaptation of the yeast to the hydrolysate resulted in a significantly highe...

Background The xanthan gum production has been growing significantly. It is estimated an annual increase by about 5 to 10%. The production needs a carbon source in fermentation media and are commonly employed as glucose or sucrose, which accounts for about 50% of the cost of production. Therefore the use of agro-industrial residues, such as corn cob for the production of xanthan gum becomes sug...

fast pyrolysis is an attractive technology for biomass conversion, from which bio-oil is the preferred product with a great potential for use in industry and transport. corn wastes (cob and stover) and eucalyptus wood are widely being produced throughout the world. in this study, fast pyrolysis of these two materials were examined under the temperature of 500 °c; career gas flow rate of 660 l h...

Housing adult rats on ground corncob bedding impedes male and female mating behavior and causes acyclicity in females. The suppressive effects on ovarian cyclicity are mimicked by a mitogenic agent purified from the ground corncob bedding material (corn mitogen; CM), which stimulates the proliferation of estrogen receptor (ER)-positive (MCF-7 cells) and ER-negative (MDA-MD-231 cells) breast can...
