A Modified Scheme For The Isolation And Enumeration Of Bacteria In Municipal Sewage Sludge, Kelly Ball

Masters Theses & Specialist Projects

Because of the potential health hazards associated with the use of sludge for agricultural purposes, Dudley et al (1980) published a scheme for the routine analysis of bacteria in municipal sewage sludge. In this study, the Dudley et al scheme (1980) was modified by updating some of the procedures. Aerobically digested sludge generated by the Bowling Green Wastewater Treatment Plant, Bowling Green, Kentucky, was analyzed using the modified scheme. Sludge samples were collected once every two months over a one-year period from October 1989 to August 1990.

A Preliminary Investigation Of The Effect Of Storm Events On The Concentration Of Volatile Organic Compounds In The Lost River Cave System, Warren County, Kentucky, Francis Michael Cretella

Masters Theses & Specialist Projects

Samples of cave water were analyzed for volatile organic compounds during four separate storm events. The major compounds detected were toluene, 1,1,1-trichloroethane, trans-1,2-dichloroethylene, methylene chloride, and 1,1-dicloroethane. Minor compounds detected were trichloroethylene, tetrachloroethylene, 1,1-dichloroethylene, and ethylbenzene. These compounds were detected in varying amounts at each of the three study sites. During a storm event, the levels of each contaminant changed significantly at all three sites studied. Two effects were observed when a storm event occurred. The first effect was the dilution of the volatile organic compounds during the storm event. These effects were related to the amount of rainfall and …

A Bacteriological And Chemical Analysis Of Nonpoint Source Pollution In A Karst Aquifer Bowling Green, Kentucky, Wayne Green

Masters Theses & Specialist Projects

Monthly water samples collected from four sites in the Lost River Groundwater Basin, a shallow karst aquifer in the Bowling Green-Warren County area of Kentucky, represented samples from sites receiving conduit and diffuse flow. All sites were severely contaminated with bacteria, and on some occasions the surface water criteria for some heavy metals were exceeded.

Of the total 334 bacterial colonies identified 92.1% were verified as Escherichia coli by the API20E system. Acinetobacter calcoaceticus var. anitratum accounted for 2.10% of colonies; Citrobacter freundii for 0.30% Klebsiella pneumoniae for 0.90%; Klebsiella oxytoca, 0.90%; Citrobacter amalonaticus 0.30%; Enterobacter cloacae, 1.20%; …

Spatial Distribution & Temporal Occurrence Of Rotifers In The Main Pool & Tailwater Of Barren Lake, Kentucky, David Abel

Biology Graduate Theses

A study of the spatial distribution and temporal occurrence and diversity of rotifers in relation to certain chemicophysical parameters was conducted in Barren Lake, Kentucky, a flood control lake, from January, 1970, through January, 1970. Paired samples were collected from six depths in the main pool area of the reservoir and from an automatic plankton sampler installed in the tailwater area where, from April through September, the effluent was derived from the upper 3 m of the pool . Diel studies were conducted in April, July, 1970, and January, 1971.

Barren Lake began to stratify in late April, was completely …

Description And Seasonal Variation In Incidence Of A New Species Of Myxosporidian Parasite (Class Myxosporidea) Of The Bluegill Sunfish, Lepomis Macrochirus Rafineque, In Kentucky, Stephen Bayes Crider

Masters Theses & Specialist Projects

A new histozoic myxosporidian parasite (Class Mysoxporidea), Myxobolus meglitschi sp. nov., infecting young-of-the-year and yearling bluegill sunfish, Lepomis macrochirus Raf., from Shanty Hollow Lake, Warren County, Kentucky was described. Phenology was investigated from January 20 to December, 1969.

The magnitude of infection varied seasonally in bluegill. Incidence was highest in July and August (43.92) in host populations, declining, but not disappearing from September to December 20, 1969. The infection exhibited a yearly mean incidence of 22.318.

The pattern of distribution of cysts on hosts varied seasonally. During periods of low incidence cysts were confined primarily to a postanal area below …

Investigation In The Physiology Of The Spore Formation Of Pseudoples Trifolii (Rostr.) And Petr., Emory S. Crosby

Masters Theses & Specialist Projects

Plant pathologists have worked to some extent for many years in an attempt to describe the complete physiology of the organism responsible for pepper spot of clover, particularly as found on white clover (Trifolium repens, L.). These works have not been extensive or concentrated and at the present time, no definite conclusions have been reached.

The causal agent of pepper spot of clover is Pseudoples trifolii (Rostr.).

Pseudoples trifolii usually is found parasitizing clover in the early spring and continues throughout the spring until the temperature exceeds thirty degrees centigrade. Elliott established that Pseudoples trifolii will not produce infectious spores …
