Aquatic microenvironments in bacterial ecology and diversity
Molecular surveys have revealed tremendous bacterial diversity in the world's oceans; yet how do these diverse bacteria with the same essential nutrient requirements co-exist in the same environment? This study examines the role of aquatic microenvironments in generating bacterial diversity: …

The bacterial ecology and function from a sub-surface critical zone
… critical zone. Molecular analysis of the bacterial 16S rRNA gene indicates that the presence of plants at the soil surface influences the bacterial diversity and composition. Cultivation of microorganisms produced several bacterial isolates; most of which were capable of mineral phosphate …

Effects of Freshwater Salinization and Associated Base Cations on Bacterial Ecology and Water Quality
… salt concentrations (≤ 1,500 µS cm-1) on bacterial ecology, despite the pervasiveness of freshwater salinization. Bacteria perform many fundamental ecosystem processes (e.g. biogeochemical cycling) and serve as indicators of human health risk from exposure to waterborne pathogens. Thus, to …

Investigation of bacteria associated with Australian wine grapes using cultural and molecular methods
… thesis presents a systematic investigation of bacterial species associated with wine grapes cultivated in Australian vineyards during 2001-2004. Grapes, sampled throughout cultivation, were analysed for bacterial species using a combination of cultural and molecular methods. Red (Shiraz, …

Collective dynamics in flowing suspensions of swimming micro-organisms
… as in oceans where motility could influence bacterial ecology and the role of bacteria in oceanic biogeochemistry. Moreover, we can investigate their rheological properties, which have recently been reported to show unexpected behaviors. In the first part of this work, we investigate the …
