Abstract

Experiments were performed to evaluate the effectiveness of two different methodological approaches for recovering DNA from soil and sediment bacterial communities: cell extraction followed by lysis and DNA recovery (cell extraction method) versus direct cell lysis and alkaline extraction to recover DNA (direct lysis method). Efficiency of DNA recovery by each method was determined by spectrophotometric absorbance and using a tritiated thymidine tracer. With both procedures, the use of polyvinylpolypyrrolidone was important for the removal of humic compounds to improve the purity of the recovered DNA; without extensive purification, various restriction enzymes failed to cut added target DNA. Milligram quantities of high-purity DNA were recovered from 100-g samples of both soils and sediments by the direct lysis method, which was a greater than 1-order-of-magnitude-higher yield than by the cell extraction method. The ratio of labeled thymidine to total DNA, however, was higher in the DNA recovered by the cell extraction method. than by the direct lysis method, suggesting that the DNA recovered by the cell extraction method came primarily from active bacterial cells, whereas that recovered by the direct lysis method may have contained DNA from other sources.

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.
