Factors limiting microbial growth and activity at a proposed high-level nuclear repository, Yucca Mountain, Nevada
Article Abstract:
Volcanic tuff from Yucca Mountain was analyzed for microbial growth and activity as part of a study evaluating the area's potential as a high-level nuclear waste site. Studies were also done on the possibility of microbial mineralization of organic substrates and on factors that may restrict microbial growth on volcanic tuff. Results of the study showed that samples of the volcanic tuff studied yielded very little microbial growth. The absence of water in the samples may have restricted the growth of bacteria.

Survival and phospholipid fatty acid profiles of surface and subsurface bacteria in natural sediment microcosms
Article Abstract:
Starvation survival capacities of surface and subsurface strains of Pseudomonas fluorescens and a novel Arthrobacter sp. were compared in microcosms made of natural sediments to determine whether subsurface conditions affect microbial survival. Findings showed that the Arthrobacter strains survived better than P. fluorescens strains. However, differences in survival between surface and subsurface strains of each genus were not significant.

Diversity within a colony morphotype: implications for ecological research
Article Abstract:
The veracity of estimating diversity and equitability ecological indices for recoverable microbial communities with colony morphology as the selection criterion is discussed. Bacterial isolates from the same colony bu with unique morphologies were subjected to API-rapid-NFT and fatty acid methyl ester analysis. Metal resistance was found to be more reliable for tracking with colony morphology than antibiotic resistance.
