Effect of increasing trimethylamine and organic matter concentration on stable carbon isotopes of methane produced in hypersaline, substrate limited environments
(University of Missouri--Columbia, 2013)
Substrate limitation has been proposed as an explanation for 13C enriched methane production from endoevaporite microbial communities in hypersaline environments. To test this possibility, methane production rates and ...
Dominant substrates used by methanogens in hypersaline environments
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The central goal of this study was to determine the dominant substrates used by methanogens in the salt ponds of Elkhorn Slough, the Don Edwards ...
Organic sulfur metabolisms in Eastern Lau Spreading Center hydrothermal vents
(University of Missouri--Columbia, 2012)
. The cultures contained species of Thermococcales, [mu]-Proteobacteria, Thermales, and Aquificales as well as 2 novel bacterial sequences. These data suggest that organic sulfur-based metabolisms may be viable within deep-sea hydrothermal vents....
Organic matter remineralization in the sediment of two acid mine drainage lakes
(University of Missouri--Columbia, 2013)
Acid mine drainage is a significant environmental problem throughout the world. At Rocky Forks Conservation Area near Columbia, MO numerous lakes have formed from old coal mining pits. Most of these lakes have a pH near ...
