The anaerobic biodegradation of ethylcyclopentane and intermediates of benzoate metabolism by microorganisms from a hydrocarbon-contaminated aquifer.
(2003)
In this thesis, I examine the microbial degradation of an alicyclic hydrocarbon and the intermediates of benzoate decay under anaerobic conditions. Ethylcyclopentane was chosen as a model alicyclic hydrocarbon because GC ...
A study of the interaction between alfalfa (Medicago sativa) and one of its fungal pathogens, Colletotrichum trifolii.
(2001)
The alfalfa/C. trifolii interaction follows a gene-for-gene interaction for race-cultivar specificity where in general, products of host resistance genes providing resistance to the fungus are interacting with direct or ...
Cloning, characterization, expression and localization of inosine-5'-monophosphate dehydrogenase (IMPDH) cDNA/mRNA in soybean (Glycine max) nodules.
(2000)
The technique of in situ hybridization was used to localize the IMPDH mRNA in soybean nodules. Mature nodules were fixed in 4% paraformaldehyde and 0.25% glutaraldehyde, dehydrated and embedded in Paraplast. Sections of ...
The reduction of uranium by sulfate-reducing bacteria in the terrestrial subsurface and a pure culture bacterium.
(2002)
The microbial reduction of uranium was investigated in a contaminated aquifer and with a pure culture model organism, Desulfovibrio vulgaris Hildenborough. The concentrations of Fe(III), U(VI), nitrate and sulfate were ...
Cell-cell interactions in Myxococcus xanthus.
(2004)
Myxococcus xanthus, a Gram-negative, rod-shaped, nonpathogenic soil bacterium has been used as a model organism for many years for research on developmental behavior such as multicellular morphogenesis, signal transduction. ...
Bacillus mojavensis and Bacillus subtilis require DNA or deoxyribonucleosides for anaerobic growth.
(2004)
Bacillus mojavensis strain JF-2 grows to an A600 of 0.8 to 1.0 in aerobic medium E but growth in this medium under strict anaerobic conditions is difficult to establish and replicate. Anaerobic growth of JF-2 was not ...
Cytosolic delivery of mutant forms of toxin B from Clostridium difficile facilitates characterization of the intracellular activities of large clostridal toxins.
(2002)
Clostridia are gram-positive spore-forming organisms responsible for a variety of diseases in both humans and animals Three species of Clostridia- Clostridium difficile, Clostridium sordellii and Clostridium novyi- produce ...
Role of ppGpp in regulating global gene expression in Escherichia coli.
(2009)
Bacteria grow when nutrient availability supports basic biochemical requirements and remain in stationary phase when basic needs go unmet. This deceptively simple phenomenon requires the orchestrated expression of thousands ...
Characterization of Subsurface Microbial Communities Involved in Bioremediation of Uranium and Nitrate
(2009)
Mining and enrichment of uranium (U) for nuclear weapons and energy has left this radionuclide an important groundwater contaminant in the United States and worldwide. Migration of U in groundwater can be prevented by U ...
Discovery, isolation and characterization of novel biomolecules with nematicidal activity.
(2000)
Both, sesquiterpene lactones isolated from Ambrosia and trypsin inhibitors isolated from Cassia and from Mucuna are new potential tools to engineer transgenic plants with resistance to plant parasitic nematodes.
