Detection of Fermentative Variants with Tetrazolium.
While trying to develop methods for finding dehydrogenase mutants, we found tetrazolium (triphenyl tetrazolium chloride) to be useful for detecting fermentative variants. This indicator has the advantage that the nonfermenting variants are stained a deep red whereas the fermenters and the background are neutral. For example, cultures of Escherichia coli K-12 were spread on nutrient agar plates ...
متن کاملDetection of rough dissociants of Pasteurella pestis with tetrazolium chloride.
Lederberg (J. Bact., 56, 695, 1948) reported the use of triphenyl tetrazolium chloride to detect fermentative variants of Ewherichia coli K-12. We have found that smooth and rough colonies of Pasteurella pestis could be identified easily when grown on tryptose (Difco) agar containing this compound. On many routine and modified laboratory media that did not contain tetrazolium, differentiation w...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Concept drift detection in event logs using statistical information of variants
In recent years, business process management (BPM) has been highly regarded as an improvement in the efficiency and effectiveness of organizations. Extracting and analyzing information on business processes is an important part of this structure. But these processes are not sustainable over time and may change for a variety of reasons, such as the environment and human resources. These changes ...
متن کاملMolecular Detection of Novel Genetic Variants Associated to Anaplasma ovis among Dromedary Camels in Iran
To the best of our knowledge, little information is available regarding the presence of Anaplasma species in camels in Iran. This study sought to investigate the presence of Anaplasma species by microscopy and polymerase chain reaction (PCR) assays in 100 healthy dromedaries (Camelus dromedarius) arriving for slaughter. The microscopic examination of Giemsa-stained blood films revealed that Ana...
