Reduction of tetrazolium salts by pleuropneumonialike organisms.
Tetrazolium salts have proved useful as indicators of electron transfer. Compounds such as triphenyltetrazolium chloride' are more practical than indicators like methylene blue since they are converted from a soluble colorless salt to an insoluble formazan in the reduced state. They also provide similar convenience in detecting enzymatic activity and specific sites of such activity (Bielig, Kau...
متن کاملQuantitative measurement of bacterial growth by the reduction of tetrazolium salts.
Tetrazolium salts can be used for measuring the reducing activity of microbial cultures colorimetrically, because the reduced form of these redox indicators is conspicuously colored (B. Jambor, Tetrazolium Salze in der Biologie, G. Fischer, Jena, 1960; B. J. Liska et al., J. Dairy Sci. 41:776, 1958). In an actively growing culture, the reducing activity is proportional with the number of bacter...

15 صفحه اولAcceleration of tetrazolium reduction by bacteria.
Conditions were assessed which would permit more rapid recognition of bacterial growth than has been previously reported using tetrazolium salts. Microtitration trays were used. 2-(p-Iodophenyl)-3(p-nitrophenyl)-5-phenyltetrazolium chloride is rapidly reduced by respiring cells in tissue homogenates but is more toxic than other tetrazoliums when added to growing bacterial cultures. Phenazine me...

ÖZ E T Bu çalışmada tetrazolyum tuzları ve formazanların yapıları tanımlanmıştır. Ayrıca formazan-tetrazolyum sistemlerinin önemi ve kullanım alanları açıklanmıştır. Formazanların sahip oldukları conjugate p-system kaynaklanan tautomerleşme özellikleri ve geometrik izomerleri incelenmiştir. Bu bileşiklerin en yaygın kullanılan sentezleri ve yapılarının açıklanmasında önemli olan UV-visible, IR ...
