Degradation of Ursolic Acid, a Major Component of Apple Wax, by a Pseudomonad Isolated from Soil

“…The dried material was refluxed under nitrogen with a mixture of chloroform + methanol ( 2 + I , v/v) for 8 hr. The chloroform-soluble material was recovered after acidifying the mixture with HCl according to the method of Folch et al (1957). The extracts obtained were concentrated in vacuo, made to volume and the radioactivity determined.…”
