Macrofiber properties of the Bacillus subtilis strain carrying a transposon insertionSu, Ling-Ing, 1961- January 1990 (has links)
Recently, a new strain of B. subtilis (Bull913) carrying Tn917, a Streptococcus-derived transposon that confers erythromycin and lincomycin resistance, in the host chromosome has been isolated that grows as multistrand helical structures. Bull913 can produce macrofibers whose properties are like another B. subtilis strain FJ7. FJ7 is a lyt-2 mutant produced by chemical mutagenesis which can form macrofibers with twists ranging from right to left handed. Bull913 also has this spectrum of twisted states. Bull913 macrofibers are similar to FJ7 but are longer lived than FJ7. The Macrofiber properties of Bull913 were compared to FJ7 using growth in liquid media supplemented with (NH₄)₂SO₄ or MgSO₄ -- conditions giving LH or RH macrofibers, respectively for FJ7. The autolysin activities and cell walls substrate properties of Bull913 were biochemically analyzed and compared to those of strains 168 and FJ7. Polyacrylamide gel electrophoresis (PAGE) was used to compare the wall proteins from all three strains. Finally, genetic studies of Bull913 were carried out to determine if the defect in Bull913 is in the lyt-1, lyt-2 or lyt-15 genes, or in a new gene. Both biochemical analysis and genetic studies suggest that Bul1913 carries Tn917 in the lyt-2 gene.

Inactivation of Naegleria fowleri amoebas by copper:silver and chlorineCassells, Janet Marie, 1957- January 1990 (has links)
Electrolytically generated copper and silver ions (400:40 and 800:80 μg/L) with and without chlorine (1 mg/L) were evaluated for their efficacy in reducing numbers of viable Naegleria fowleri amoebas in well water (23-25°C and pH 7.3). A 99.9% reduction was achieved by 10 minutes exposure to 1 mg/L free chlorine compared to 8 minutes with chlorine combined with copper:silver (800:80 μg/L). Copper:silver alone showed minimal reduction of N. fowleri after 72 hours exposure. Addition of 1 mg/L free chlorine to copper:silver at concentrations of 400:40 or 800:80 μg/L resulted in significantly enhanced inactivation rates (k = 0.4575 and 0.515 log₁₀ reduction/minute, respectively) than with chlorine alone (k = 0.33). Enhanced inactivation of N. fowleri with combined copper:silver and chlorine may be a consequence of multiple sites of attack on the amoeba membrane by the different disinfectants.
