The Isolation and Estimation of the Poly- -hydroxy-butyrate Inclusions of Bacillus Species
Abstract
SUMMARY: Treatment of the cells of various Bacillus spp. with an alkaline solution of sodium hypochlorite resulted in dissolution of the cells and liberation of the intracellular lipid inclusion bodies. Analyses of the isolated and purified inclusions of Bacillus cereus grown under a variety of cultural conditions showed them to contain about 89 % poly-β-hydroxybutyrate and 11% ether-soluble lipid. Parallel estimations of the poly-β -hydroxybutyrate content of intact organisms by Lemoigne’s chloroform extraction method showed that all of it was present in the lipid inclusions. These observations form the basis of a simple and rapid method of estimating the poly-β-hydroxybutyrate content of Bacillus spp. It consists essentially of digesting a washed bacterial suspension with a standard alkaline hypochlorite solution under standard conditions and measuring the residual turbidity.

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.
