The alkaline cooking of corn in a solution of Ca(OH)2 to produce corn-based foods is oriented to make corn proteins available, to incorporate Ca to the cooked grains, and also to remove the corn hull. This process (nixtamalization) is known in Mexico and Guatemala from prehispanic times; however, the effect of the alkaline cooking on the corn hull remains poorly documented. In this work, the ph...

Bleomycin-induced breakage of an isolated covalently closed circular DMA from bacteriophage PM2 was as sayed fluorometrically after agarose gel electrophoresis and staining with ethidium bromide. When bleomycindamaged DMA was assayed under neutral conditions, there was a decrease in the amount of Form I DMA and a simultaneous increase in both Forms II and III of DMA. However, when the damage wa...

Abstract The establishment of sustainable bioeconomies requires the utilization new renewable biomaterials. One such material currently seen as a waste product is oat hulls. Oat hulls exhibit great potential for production dietary fibres due to their exceptionally large hemicellulose content (35%). Their recalcitrant structure however suitable pre-treatment method access and process hemicellulo...
