Molecular Biology of Sulfate Reducing Bacteria In this project, we have a considerable ongoing effort. This work will identify genes and ultimately physiological activities that are critical to the function of anaerobic bacteria that live and grow in contaminated sediments. Our hypothesis is that sediment dwelling microorganisms have unique functions, encoded at the genetic level that are manifest only during exposure to contaminated environments. Further, we believe that these activities are not detectable using traditional in vitro laboratory incubations and therefore we are studying the bacteria under more natural, in situ, conditions. We are identifying genes of sulfate reducing bacteria (SRB) whose expression is necessary for the survival and activity of these organisms in contaminated environments. This involves the extrapolation of a molecular approach that has already proven successful for identifying genes expressed by pathogens only when these organisms are growing in a suitable host (in situ) and not when the organisms are in culture. Our approach takes on an ecological perspective. We are asking which genes are expressed by sulfate reducers when they are exposed to and/or degrading a myriad of contaminants in sedimentary systems as opposed to those genes that may be expressed in laboratory cultures.

Bizarre Facts in Biology Extreme Bacteria! By Gail Gasparich Imagine life in the most inhospitable of environments, an environment without oxygen or with extremely high salt concentration or with boiling hot acid. How could any organism live there? All of the animals and plants that we are familiar with would find these conditions uninhabitable. How could a cell's plasma membrane and large molecules remain stable and functional under these conditions? How can these very different, extreme environments be home to a unique group of microorganisms, the Archaea? This interesting group of microbes is unique; they have thrown the whole classification system for living organisms upside down. Some characteristics of Archaea are closely related to bacteria, whereas other characteristics show a relationship to eukaryotes. But archeans have many distinctive properties that set them apart from bacteria or eukaryotic organisms. Their cell wall and plasma membrane composition's are unique as is their ribosomal RNA . What does this mean from an evolutionary perspective? The dilemma arose when scientists were deciding where to place these organisms in relation to all other organisms on Earth. Where do they belong, with the bacteria or in their own group? Dr. Carl Woese made the suggestion that the Archaea should be one of three new superkingdoms or domains of organisms, with all bacteria making up the second domain and all eukaryotic organisms making up

Soil biology page Soil biology research areas CRICOS Provider No: 00126G The ecology of root-nodule bacteria associated with legume species in south -western Australia Description of research This area of research is aimed at relating knowledge of the diversity of rhizobia and bradyrhizobia in soils of south-western Australia with their presence in legume nodules, and the impact of farming systems on nodule occupancy. Current projects are: Community structure of populations of clover rhizobia associated with pastures This research is identifying the soil factors and management practices associated with a low proportion of nitrogen fixed by pasture legumes. The research is using ELISA and PCR techniques to characterize nodule occupancy and relate this to changes in soil conditions due to rotation with canola and oats, and to incorporation of organic matter. Margaret Collins Janice Thies Lyn Abbott Funding: CLIMA Dynamics of field populations of bradyrhizobia associated with serradella Nodule occupancy and population densities of bradyrhizobia under inoculated serradella has been assessed at two field sites. The populations under lupin, serradella and native vegetation have been compared and the potential for native legumes to act as alternative hosts for serradella bradyrhizobia is being determined. Competitive interactions between field isolates of bradyrhizobia are being related to frequency of nodule occupancy in the field.

It is the use of various types of bacteria by a host eukaryote to kill other types of invading microbes, including both bacteria and fungi. Why are there so many "dairy bacteria" in MILK ? Are they of benefit to the baby? Perhaps, more importantly, are they of benefit to the mother? How is that they get from the mother's gastrointestinal tract and into her milk ducts in huge numbers within hours? This is a very hot project that is highly likely to be accepted for international presentation in professional society conventions. What are the "dairy bacteria" doing inside of LEAVES ? Are they protecting the tender and moist spongy cells from invasion from environmental microbes that might waft through the pores (stomata) and into the interior air spaces? This also is a very hot project that is highly likely to be accepted for international presentation in professional society conventions.

Bacteria/Cell Biology Student's name: Sonia Tikoo Grade: 9th School: Outside of Oregon Category: Life_Science.Cell Expert: Walt Ream First, I would not get bacteria out of a restroom stall for two reasons. One, it is potentially dangerous, because you will have no idea what organisms you will culture from that environment. The collection could include pathogens, and you don't want to work with large cultures of those without a good reason and proper protection. Two, it is not good science. It is not much use to know whether light affects the growth of an unknown bacterium. Each species is different, so you need to know what species you have before you start. Otherwise your data will not mean much. I suggest you go to a lab or a culture collection and ask for a nonpathogenic strain of Escherichia coli K-12. You also need to make sure your culture vessel does not block transmission of the wavelength of light that interests you. I can tell you that a sufficient does of UV light will either retard or prevent the growth of most bacteria, but glass flasks and plastic Petri dishes both
