The Biodegradation Of Crude Oil By Bacteria Isolated From Brine Pits, Larry Williams
The Biodegradation Of Crude Oil By Bacteria Isolated From Brine Pits, Larry Williams
Masters Theses
The biodegradation of crude oil by bacteria was studied. Hydrocarbon-utilizing bacteria were isolated from sixteen brine pits from an oil producing region of Clark County, Illinois. The bacteria were capable of growth from the vapors arising from crude oil as a sole carbon source. Some strains of bacteria were capable of emulsifying crude oil, apparently through the production of an emulsifying agent(s) that was found to be heat stable and cell bound but which can be partially stripped from the cell by autoclaving. The bacteria appear to belong to the genus Arthrobacter. The chemical environment of the pits was …
Studies Of The Lysogenic Response As A Function Of Multiplicity Of Infection Of Lambdoid Bacteriophages, Mark Floyd Fedyk
Studies Of The Lysogenic Response As A Function Of Multiplicity Of Infection Of Lambdoid Bacteriophages, Mark Floyd Fedyk
Masters Theses
The lambdoid bacteriophages λimmλ, λimm434 and λcI are ideal subjects for the study of gene product interactions at the molecular level due to their closely related genetic makeup. Previous work in this laboratory has indicated the possibility that phage λimm is sensitive to phage λimm434cI gene product and that phage λimm434 is sensitive to phage λimmλcI gene product. The purpose of this research was to determine if the frequency of lysogeny for phage λimmλ is affected by the multiplicity of coinfection with the λimm434 phage. By comparing the graph of …
Siderocapsa Major-- Fact Or Artifact?, Ray W. Swanson
Siderocapsa Major-- Fact Or Artifact?, Ray W. Swanson
Masters Theses
The validity of the genus Siderocapsa, a group of unicellular iron-depositing bacteria, has been a subject of debate for many years. Lack of photomicroscopic and cultural studies has kept this group in taxonomic obscurity. Bacteria were collected from the Campus pond, Eastern Illinois University, Charleston, Illinois, by a submerged slide/coverslip technique. These bacteria were identified as Siderocapsa major according to the description of Molisch (1909). Scanning electron microscopy of Siderocapsa major microcolonies has shown cells (0.5 by 1.15 μm), in a clear central well (2-6 μm), surrounded by an amorphous material which accumulates with the age of the colony. …
Bacteriophage Populations In Wastewater Effluent, Guy William Lawrence
Bacteriophage Populations In Wastewater Effluent, Guy William Lawrence
Masters Theses
Effluent samples were taken at various stages of sewage treatment at a local wastewater treatment plant. Primary, secondary, tertiary and post-chlorinated effluents were sampled. The agar overlay method was used to determine the numbers of plaque-forming bacteriophage particles on thirty-six species of enteric bacteria from the Eastern Illinois University stock culture collection. Twenty-three pure culture phage isolates were prepared from selected plaques and their host range specificity was determined. For every host organism tested, a fifty percent or greater reduction of bacteriophage was evident through the sewage treatment process. Results obtained from investigation of host range specificity indicate that potential …
