Comparison of Methods for Extraction of Bacterial Adenine Nucleotides Determined by Firefly Assay

Open access
Arne Lundin, Anders Thore·1975·Applied Microbiology

Abstract

Adenine nucleotides in Escherichia coli, Bacillus cereus, Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa were extracted using 10 different methods. Extracts were assayed for adenosine 5'-triphosphate (ATP), adenosine 5'-diphosphate (ADP), and adenosine 5'-monophosphate (AMP) by the firefly method using an improved procedure. Analytical interference by bacterial enzymes not inactivated during the extraction was found to be a major problem. However, these enzymes were inactivated to a considerable extent by the inclusion of ethylenediaminetetraacetate in the extraction reagent. The 10 extraction methods were compared with respect to yield of adenine nucleotides, interference with the enzymic assay, reproducibility of the method, and stability of the extracts. Results indicated that extraction with trichloroacetic acid was the method most closely reflecting actual levels of ATP, ADP and AMP in intact bacterial cells. However, for the extraction of ATP in some bacterial strains several other methods may be used and may be advantageous from a practical point of view.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
