  1. Genetic manipulation of polyamine metabolism in poplar

    Using a variety of gene transfer techniques, it is now possible to introduce foreign genes into plant cells, which can be used for analysis of expression of the foreign genes.

  2. Monitoring environmental stress in forest trees using biochemical and physiological markers

    Our objective was to determine the usefulness of polyamines, particularly putrescine, and amino acids such as arginine, as foliar indicators of abiotic stress in visually asymptomatic trees. An evaluation of apparently healthy trees is essential in developing risk assessment and stress remediation strategies for forest trees prior to the onset of obvious decline....

  3. Dilute acid pretreatment of corncob for efficient sugar production

    Aqueous dilute acid pretreatments of corncob were conducted using cylindrical pressure vessels in an oil bath. Pretreatments were conducted in a temperature range of 160–190 °C with acid-solution-to-solid-corncob ratio of 2. The acid concentration (v/v) in the pretreatment solution was varied from 0% to 0.7%, depending on temperature. This gives acid charge on ovendry-...

  4. Interactions of fungi from fermented sausage with regenerated cellulose casings

    This research examined cellulolytic effects of fungi and other microbes present in cured sausages on the strength and stability of regenerated cellulose casings (RCC) used in the sausage industry. Occasionally during the curing process, RCC would split or fail, thereby leading to loss of product. The fungus Penicillium sp. BT-F-1, which was isolated from fermented...

  5. Evaluation of ethanol production from corncob using Scheffersomyces (Pichia) stipitis CBS 6054 by volumetric scale-up

    In scale-up, the potential of ethanol production by dilute sulfuric acid pretreatment using corncob was investigated. Pretreatments were performed at 170 °C with various acid concentrations ranging from 0% to 1.656% based on oven dry weight. Following pretreatment, pretreated biomass yield ranged from 59% to 67%. More than 90% of xylan was removed at 0.828% of sulfuric...

  6. Xylitol production from DEO hydrolysate of corn stover by Pichia stipitis YS-30

    Corn stover that had been treated with vapor-phase diethyl oxalate released a mixture of mono-and oligosaccharides consisting mainly of xylose and glucose. Following overliming and neutralization, a D-xylulokinase mutant of Pichia stipitis, FPL-YS30 (xyl3 -Ä1), converted the stover hydrolysate into xylitol. This research examined the effects of phosphoric or gluconic...
