I use tetrazolium red to indicate metabolic activity of micro-organisms
(Pseudomonads) on certain carbon sources. Some references point to the
usefulness of this method, e.g. J.Lederberg showed that:
- bacteria grown on non- acidifying carbon sources in the agar plate turn
tetrazolium red to a red color;
- bacteria grown on acidifying carbon sources (fermentation: glucose,
lactose) do not convert terazolium
My problem is, that I seem unable to find out, or at least get some
literature, on the bacterial enzymes and reactions that convert
tetrazolium. Lederberg wrote about a "dehydrogenase".
Can anyone give some hints where to look in literature ??
Just wondering what I'm looking at......
