Description
Technical field
The present invention relates to microorganism indole test instrument technical field more particularly to a kind of environment-friendly microbial indole tests
Instrument.
Background technique
It is one of the experiment that must be done that in microbial physiology biochemical test, indoles, which generates experiment, when originally carrying out indole test
Indoles that tryptophan generates is extracted because ether is added and is enriched to ether layer, could be added later to dimethylamino benzene first
Aldehyde effect, generates red rosindol, and since the indoles amount of generation is limited, what is be not enriched with or be enriched with is bad, to observe
Good experimental result is all very difficult, in this way after the amount of dropwise addition ether, dropwise addition multiple oscillation, and the standing 1-3 after oscillation divides
Clock is all the technology that must be held very well, with greater need for very small when Paradimethylaminobenzaldehyde especially is added dropwise after ether layering
The indoles that careful slowly the adding just along test tube wall of the heart can guarantee extracting to ether layer will not re-mix in fermentation liquid, also
It can guarantee that indoles and Paradimethylaminobenzaldehyde effect produce red compound rosindol, never shake test tube at this time,
Ether layer is destroyed, otherwise red positive findings are also difficult to occur.
Existing biology indole test instrument is not easy to instill indole reagent in test tube, be easy there are still some shortcomings
By human factor cause false negative as a result, and be not easy to separate ether, in turn result in the pollution of environment, be not able to satisfy
The use demand of personnel, therefore we have proposed a kind of environment-friendly microbial indole test instrument for solving the above problems.
