Determination of the sedimentary microbial biomass by extractible lipid phosphate
TLDR
The high content of plasmalogen phospholipids in these sediments suggests that the anaerobic prokaryotic Clostridia are found in the aerobic sedimentary horizon, which would require anaer aerobic microhabitats in the aerated zones. Expand
Polyphasic taxonomy of the genus Shewanella and description of Shewanella oneidensis sp. nov.
TLDR
This polyphasic taxonomy takes into account all available phenotypic and genotypic data and integrates them into a consensus classification of Shewanella species based on information generated from this study and obtained from the literature. Expand
Stimulating the In Situ Activity of Geobacter Species To Remove Uranium from the Groundwater of a Uranium-Contaminated Aquifer
TLDR
The results demonstrate that in situ bioremediation of uranium-contaminated groundwater is feasible but suggest that the strategy should be optimized to better maintain long-term activity of Geobacter species. Expand
Geobacter metallireducens gen. nov. sp. nov., a microorganism capable of coupling the complete oxidation of organic compounds to the reduction of iron and other metals
TLDR
Profiles of the phospholipid ester-linked fatty acids indicated that both the anaerobic desaturase and the branched pathways for fatty acid biosynthesis were operative, and the 16S rRNA sequence indicated that this organism belongs in the delta proteobacteria. Expand
Phospholipid, ester-linked fatty acid profiles as reproducible assays for changes in prokaryotic community structure of estuarine sediments
Phospholipid, ester-linked fatty acid profiles showed changes in benthic prokaryotic community structure reflecting culture manipulations that were both quantitative and statistically significant.Expand
PLANT DIVERSITY, SOIL MICROBIAL COMMUNITIES, AND ECOSYSTEM FUNCTION: ARE THERE ANY LINKS?
TLDR
Evidence from a long-term field manipulation of plant diversity that soil microbial communities, and the key ecosystem processes that they mediate, are significantly altered by plant species richness is provided. Expand
Compositional and functional shifts in microbial communities due to soil warming
TLDR
Substrate pools for microbial respiration and the abundance of PLFA and LPS-OHFA biomarkers for Gram-positive and Gram-negative bacteria differed significantly among temperature treatments, providing evidence for a shift in the function and composition of microbial communities related to soil warming. Expand
Phospholipid ester-linked fatty acid profile changes during nutrient deprivation of Vibrio cholerae: increases in the trans/cis ratio and proportions of cyclopropyl fatty acids
TLDR
The ability to either synthesize trans-monoenoic fatty acids or modify the more volatile cis-monoic acids to their cyclopropyl derivatives may be a survival mechanism which helps maintain a functional (although structurally altered) membrane during starvation-induced lipid utilization. Expand
Microbial Population Changes during Bioremediation of an Experimental Oil Spill
TLDR
PLFA analysis indicated that by week 14 the microbial community structures of the oiled plots were becoming similar to those of the unoiled controls from the same time point, but DGGE analysis suggested that major differences in the bacterial communities remained. Expand
Lipid analysis in microbial ecology: quantitative approaches to the study of microbial communities.
TLDR
Analytical techniques developed in the last decade offer insights into the nature of microorganisms, primarily in recycling biologically important elements within ecosystems. Expand
