A METHANOL-UTILIZING BACTERIUM: I. DESCRIPTION AND NUTRITIONAL REQUIREMENTS

Abstract

A Pseudomonas isolated from soil, capable of growing on a medium containing methanol as the only carbon source, is described. Biotin or one of a few closely related compounds is required in very low concentrations as a growth factor. It is shown that the ability to use methanol is an adaptive system and that the biotin is incorporated in the cell, but is recoverable on acid hydrolysis.
