Carbon Monoxide-Dependent Chemolithotrophic Growth Of Clostridium Thermoautotrophicum, M. Dean Savage, Zhongren Wu, Steven L. Daniel, Leon L. Lundie Jr, Harold L. Drake Aug 1987

Carbon Monoxide-Dependent Chemolithotrophic Growth Of Clostridium Thermoautotrophicum, M. Dean Savage, Zhongren Wu, Steven L. Daniel, Leon L. Lundie Jr, Harold L. Drake

Steven L. Daniel

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.

Four species of the genus Cyperus are described, illustrated, and compared to their nearest relatives. These are: C. matudae and C. breedlovei (Subgenus Protocyperus) from the Pacific slope of Chiapas, Mexico; and C. wilburii and C. svensonii (Subgenus Cyperus) from the lowlands of the Isthmus of Tehuantepec, and from the uplands of Chiapas, Guatemala, Honduras, and Nicaragua, respectively.

Multiple Paternity In A Territorial Passerine: The Bobolink, Thomas A. Gavin, Eric K. Bollinger Jul 1985

Multiple Paternity In A Territorial Passerine: The Bobolink, Thomas A. Gavin, Eric K. Bollinger

Eric K. Bollinger

Electrophoretic and behavioral evidence corroborate the conclusion that Bobolink (Dolichonyx oryzivorus) females occasionally copulate with more than one male, which results in the insemination of a single clutch of eggs by those males. In 2 of 12 families from which blood samples were obtained from the mother, the putative father, and the nestlings, at least 2 males were responsible for fertilization of the clutch. We believe this is only the second bird species in which multiple paternity has been documented conclusively in the wild. Our speculation that it may not be uncommon leads to a caution for evolutionary biologists who …
