Chapter 6.2 Microbiology and Morphogenesis of Columnar Stromatolites (Conophyton, Vacerrilla) from Hot Springs in Yellowstone National Park
A systematic survey for thermophilic fermentative bacteria and archaea in high temperature petroleum reservoirs
The successful isolation of thermophilic, fermentative microorganisms from petroleum reservoirs decreased significantly with increasing salinity and temperature, which support the existence of a deep biosphere where fermentativemicroorganisms are widespread.
Occurrence of benthic microbial mats in saline lakes

Limnology developed primarily through examination of open-water planktonic systems and limnologists, as a group, still display a mystifying propensity for studies of the planktonics, faunal and chemical components of saline lake ecosystems.
Siliceous Algal and Bacterial Stromatolites in Hot Spring and Geyser Effluents of Yellowstone National Park
Growing algal and bacterial stromatolites composed of nearly amorphous silica occur around hot springs and geysers in Yellowstone National Park, Wyoming, and may be bacterial rather than algal, which has important implications in atmospheric evolution.
Planctomyces maris sp. nov.: a Marine Isolate of the Planctomyces-Blastocaulis Group of Budding Bacteria
A new marine strain of the Planctomyces-Blastocaulis group of stalked, budding bacteria was isolated, suggesting that the bacterium is indigenous to the marine environment.
Lake thetis, western australia: An example of saline lake sedimentation dominated by benthic microbial processes
Lake Thetis is a saline coastal lake in south-western Australia, a region of winter rainfall and summer drought. The lake demonstrates the close relationships between environmental variation and the…
A First Estimate of Ground Water Ages for the Deep Aquifer of the Kathmandu Basin, Nepal, Using the Radioisotope Chlorine‐36
The Kathmandu Basin in Nepal contains up to 550 m of Pliocene-Quaternary fluvio-lacustrine sediments which have formed a dual aquifer system, and the low specific discharge confirms that the resource is being mined, and reserves will be used up within 100 years.
Benthic microbial communities of Australian saline lakes

- Environmental Science
Questions concerning the following topics are still unresolved: the quantitative importance of BMC primary production in relation to that of phytoplankton and aquatic macrophytes, the environmental factors promoting formation of BMC and their ability to compete with other primary producers, the quantitative significance of anoxygenic photoautotrophy in BMC, the effect of meiofauna on internal elemental cycling and exchange with the overlying water.
Photosynthetic and behavioral versatility of the cyanobacterium Oscillatoria boryana in a sulfide-rich microbial mat
The diel pattern of vertical migratory movements and photosynthetic activity of Oscillatoria cf. boryana was monitored periodically in microbial mats of a shallow tepid pond fed by sulfiderich, hot,…
ALGAL EXCRETION AND BACTERIAL ASSIMILATION IN HOT SPRING ALGAL MATS 1
Excretion at temperatures approaching the upper limit for growth was not significantly different from the percentage excretion values observed at lower temperatures, and 14C‐labeled organic compounds excreted during algal photosynthesis could be subsequently assimilated by natural populations of the bacteria present in the mat.
