(Taylor & Francis LTD, 2003)Some 2-substituted-1H-phenanthro [9,10-d] imidazole compounds synthesized as a predrugs were tested in mutagenicity assays in Salmonella strains TA97, TA98, and TA100 using a plate incorporation assay both with and without ... -
Development of immunomagnetic separation technique for isolation of Pseudomonas syringae pv. phaseolicola
(Springer, 2000)Immunomagnetic separation technique was developed for specific detection and selective isolation of Pseudomonas syringae pv, phaseolicola, the agent of halo-blight disease of beans. Whole-cell and exopolysaccharide fraction ... -
Multilocus enzyme electrophoresis analysis of Pseudomonas syringae pv. phaseolicola
(Folia Microbiologica, 2001)A multilocus enzyme electrophoresis technique was developed to detect variation in seven enzyme loci among isolates of Pseudomonas syringae pv. phaseolicola, representing three races from different geographical locations, ... -
Incidence and characterization of Bacillus cereus in meat and meat products consumed in Turkey
(Blackwell Publishing, 2006)A total of 100 retail samples of meat and meat products were examined for Bacillus cereus using mannitol egg yolk polymyxin (MYP) agar as a selective isolation medium. Only 22.4% of the samples contained detectable levels ... -
Mutagenic activities of ten imidazole derivatives in Salmonella typhimurium
(Springer, 2007)Ten imidazole derivatives were tested for mutagenicity in Salmonella typhimurium strains TA98 and TA100 both in the absence and presence of metabolic activation by the microsomal fraction S9 mix. In a general manner, ... -
Mutagenicity analysis of water samples from Seydisuyu (Kirka, Turkey) stream under the influence of boron production complex
(Pergamon-Elsevier Science LTD, 2007)Kirka region in Turkey is naturally high in boron content. There is also a boron production complex in our study area. Although boron was found to be neither genotoxic nor carcinogenic, mutagenicity of boron can still be ... -
