Responses of soil respiration and ecosystem productivity to climate change in southern Great Plains.
(2007)
The third is to investigate the role of precipitation on ecosystem carbon processes (i.e., biomass, litterfall, and soil respiration) along a natural precipitation gradient in southern Great Plains. Our results show that ...
Isolation and characterization of small naturally occurring plasmids from Desulfovibrio spp.
(2007)
These results suggest that these strains have different genomic organization. The presence of plasmid DNA was only detected in Desulfovibrio SR-1. On the basis of distinct phenotypic and genotypic characteristics, strain ...
Elucidating the in vivo targets of bacterial toxins.
(2007)
Abstract not available.
Novel aspects of benzoate and crotonate metabolism by the strictly anaerobic bacterium Syntrophus aciditrophicus strain SB.
(2007)
Although enzyme activities and metabolites detected in S. aciditrophicus indicated that benzoate was degraded by the pathway found in Rhodopseudomonas palustris, proteomic data detected the gene products homologous to ...
Respiration and energy metabolism of Escherichia coli in the intestine.
(2007)
Colonization of the gastrointestinal tract by Escherichia coli is dependent upon its ability to compete with the commensal microflora. We have established that nutrient acquisition is important for competition and fitness ...
Systematics of the Mecardonia acuminata (tribe Gratioleae, Plantaginaceae) complex of southeastern USA.
(2007)
Seed surface morphology is known to be of taxonomic significance in some plant taxa, and has been used as diagnostic features of some families, genera and species. The tribe Gratioleae (Plantaginaceae) consists of 16 genera ...
Genes required for sediment fitness in Desulfovibrio desulfuricans G20.
(2007)
97 genes required for sediment fitness of G20 were identified and the identification of chemotaxis genes validated our STM screening method since it would be expected to enhance sediment fitness. The growth of these sediment ...
