Wrdwood Control Using Pelleted
Treatments using combinations of pelletized herbicides with prescribe burning were tested for planting site preparation on steep terrain (>35% slopes) in the Alabama Piedmont. Mixed forests of southern pines, oaks, and hickories occupied areas before logging. Three burning treatments (no-burn, preand post-harvest) were applied randomly among three 4-acre major plots at each of three study locat...
متن کاملCellulosic ethanol production from AFEX-treated corn stover using Saccharomyces cerevisiae 424A(LNH-ST).
Current technology using corn stover (CS) as feedstock, Ammonia Fiber Expansion (AFEX) as the pretreatment technology, and Saccharomyces cerevisiae 424A(LNH-ST) as the ethanologenic strain in Separate Hydrolysis and Fermentation was able to achieve 191.5 g EtOH/kg untreated CS, at an ethanol concentration of 40.0 g/L (5.1 vol/vol%) without washing of pretreated biomass, detoxification, or nutri...
متن کامل[Concentration of nitrosodimethylamine in commercial pelleted experimental animal diets].
To know the conditions of contamination by the chemicals in the experimental animal diets, the contents of nitrosodimethylamine (NDMA) were analyzed in the diets for mice and rats. The raw materials of the diets were also analyzed. In addition, NDMA levels were determined in the diets which were stored long or heated in the autoclaves. The averages of NDMA in these diets were less than 10 ppb. ...
متن کاملComprehensive characterization of non-cellulosic recalcitrant cell wall carbohydrates in unhydrolyzed solids from AFEX-pretreated corn stover
BACKGROUND Inefficient carbohydrate conversion has been an unsolved problem for various lignocellulosic biomass pretreatment technologies, including AFEX, dilute acid, and ionic liquid pretreatments. Previous work has shown 22% of total carbohydrates are typically unconverted, remaining as soluble or insoluble oligomers after hydrolysis (72 h) with excess commercial enzyme loading (20 mg enzyme...
متن کاملPotential for Simultaneous Improvement of Corn Grain Yield and Stover Quality for Cellulosic Ethanol
Corn (Zea mays L.) stover, the residue left after harvest, is an abundant biomass source for producing cellulosic ethanol in the United States. Corn has been bred for increased grain yield but not for stover quality for cellulosic ethanol production. Our objective in this study was to assess the feasibility of breeding corn for grain yield and agronomic traits as well as stover quality traits f...
