Corn stalks are not easily degradable and thus have a low utilization rate. In this paper, highly efficient corn stalk-degrading microbial consortium, designated as SDP, was established using the strains Z22 (Bacillus subtilis), Z15 megaterium), Z08 (Aspergillus tubingensis). Moreover, fermentation conditions for enzyme production by SDP were optimized through orthogonal experiments. The Van So...

To increase the added value of corn stalk and improve performance biochar, magnesium chloride (MgCl2) was used to modify effects temperature on structure properties modified biochar were considered. With temperature, yield decreased. There a marked in number mesopores micropores, but mesopore pore diameter changed smaller diameter, specific surface area remarkably increased. As increased, conte...

compared to a 5% untreated stalk control (2013 Nebraska Beef Cattle Report, pp. 70-73). Treatment process in all of these university trials included 5% CaO (Mississippi Lime, StoverCalO, granulated quicklime) with 95% corn stalks (DM basis) and then mixed with enough water to produce a final mix that was 50% DM. No data are available using commercial treatment technologies and mixing and storin...

Zearalenol was extracted from Fusarium-infected stems of corn from southern Italy. The toxin, which appeared as a single compound in various thin-layer chromatography systems, was resolved by high-pressure liquid chromatography into two components. A gas chromatography-mass spectrometry examination of a purified fraction confirmed the natural occurrence of zearalenol as a diastereomeric mixture...

In the United States, corn (Zea mays L.) stover has been targeted for second generation fuel production and other bio-products. Our objective was to characterize sugar and structural composition as a function of vertical distribution of corn stover (leaves and stalk) that was sampled at physiological maturity and about three weeks later from multiple USA locations. A small subset of samples was...

Current bio-ethanol production entails the enzymatic depolymerization of cellulose, but this process shows low efficiency and poor economy. In work, we developed a consecutive aqueous hydrogenolysis for conversion corn-stalk cellulose to produce relatively high concentration (6.1 wt%) without humin formation. A yield (ca. 50 is extracted from corn stalk using green solvent (80 wt% 1,4-butanedio...

Existing corn harvester cutting blades have problems associated with large cutting resistance, high energy consumption, and poor cut quality. Using bionics principles, a bionic blade was designed by extracting the cutting tooth profile curve of the B. horsfieldi palate. Using a double-blade cutting device testing system, a single stalk cutting performance contrast test for corn stalks obtained ...

In order to properly determine the value of charring crop residues, the C use efficiency and effects on crop performance of biochar needs to be compared to the un-charred crop residues. In this study we compared the addition of corn stalks to soil, with equivalent additions of charred (300 °C and 500 °C) corn residues. Two experiments were conducted: a long term laboratory mineralization, and a...
