Carbon Monoxide-Dependent Chemolithotrophic Growth Of Clostridium Thermoautotrophicum, M. Dean Savage, Zhongren Wu, Steven L. Daniel, Leon L. Lundie Jr, Harold L. Drake
Carbon Monoxide-Dependent Chemolithotrophic Growth Of Clostridium Thermoautotrophicum, M. Dean Savage, Zhongren Wu, Steven L. Daniel, Leon L. Lundie Jr, Harold L. Drake
Faculty Research & Creative Activity
The acetogen Clostridium thermoautotrophicum was cultivated under CO-dependent chemolithotrophic conditions. CO-dependent growth profiles and energetics indicated that supplemental CO2 was fundamental to efficient growth at the expense of CO. Overall product stoichiometry approximated 6.5CO --> CH3CO2H + 3.5CO2 + 0.6 cell C + 0.5 unrecovered C. Initial CO/CO2 ratios of 2 to 4 yielded optimal doubling times and cell yields. Maximal YCO values approximated 2.5 g of cell dry weight per mol of CO consumed; Y H2 , was considerably lower than Y CO Cross-transfer growth experiments and protein profiles indicated differential expression of genes between CO and methanol cultures.
Microbial Degradation Of Oxalate In The Gastrointestinal Tracts Of Rats, Steven L. Daniel
Microbial Degradation Of Oxalate In The Gastrointestinal Tracts Of Rats, Steven L. Daniel
Faculty Research & Creative Activity
Rates of oxalate degradation by mixed bacterial populations in cecal contents from wlld rats ranged from 2.5 to 20.6 µmol/g (dry weight) per h. The oxalate-degrading activity in cecal contents from three strains of laboratory rats (Long-Evans, Wistar, and Sprague-Dawley) from four commercial breeders was generally lower, ranging from 1.8 to 3.5 µmollg (dry weight) of cecal contents per h. This activity did not increase when diets were supplemented with oxalate. Wben Sprague-Pawley rats from a fifth commercial breeder were fed an oxalate diet, rates of oxalate degradation in cecal contents increased from 2.0 to 23.1 µmollg (dry weight) per …

Use Of Monolploid Solanum Phureja In Cell And Tissue Culture Techniques For Potato Improvement, Henry R. Owen
Use Of Monolploid Solanum Phureja In Cell And Tissue Culture Techniques For Potato Improvement, Henry R. Owen
Faculty Research & Creative Activity
Monoploid genotypes (2n = x = 12), derived by anther culture of a diplandrous genotype of Solanum phureja, a South-American diploid potato species, were examined for their utility in germplasm development.
Nine monoploid genotypes and the diploid anther-donor plant were grown in photoperiod chambers at The Southeastern Plant Environment Laboratories (SEPEL) at North Carolina State University to examine the effect of photoperiod on tuber yield and to determine the variability for critical photoperiod for tuberization. Significant differences were found among the monoploid genotypes for total tuber weight and tuber number. Longer photoperiod treatments both decreased and delayed tuberization. Axillary tuber …
