Isolation of a bioemulsifier from Candida lipolytica
Open accessAbstract
The yeast Candida lipolytica produced an inducible extracellular emulsification activity when it was grown with a number of water-immiscible carbon substrates. Negligible emulsification activity was produced by this yeast when it was grown with glucose as the carbon substrate. In hexadecane-supplemented cultures, emulsification activity was first detected after 36 h of growth, with maximum production after 130 h. A water-soluble emulsification activity was partially purified by repeated solvent extractions of the culture filtrate. This emulsifier, which we named liposan, was primarily composed of carbohydrate. Maximum emulsification activity was obtained when the ratio of hexadecane to liposan was 50:1. Maximum emulsification activity was obtained from pH 2 to 5. Liposan was heat stable to temperatures up to 70 degrees C, with a 60% loss in activity after heating for 1 h at 100 degrees C. Liposan effected stable oil-in-water emulsions with a variety of hydrocarbons.

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.
