One of the sets of dentures was actually stolen from the Smithsonian in 1976 from a bicentennial exhibit presumably for its gold content and has never been recovered. But hereâs the most interesting part of the story about George Washingtonâs teeth â¦.
Kanamycin is a mixture of three main components: kanamycin A, B, and C. Kanamycin A is the major component in kanamycin. The effects of these components do not appear to be widely studied as individual compounds when used against prokaryotic and eukaryotic cells.acteria that have been transformed with a plasmid containing the kanamycin resistance gene are plated on kanamycin (50-100 ug/ml) containing agar plates or are grown in media containing kanamycin (50-100 ug/ml).
Natamycin (INN), also known as pimaricin and sometimes sold as Natacyn, is a naturally occurring antifungal agent produced during fermentation by the bacterium Streptomyces natalensis, commonly found in soil. Natamycin has a very low solubility in water; however, natamycin is effective at very low levels. Its minimum inhibitory concentration is less than 10 ppm for most molds. Natamycin is classified as a macrolide polyene antifungal, and as a drug, is used to treat fungal keratitis, an infection of the eye.
