Studies in the biochemistry of micro-organisms

Abstract

IN an attempt to identify certain strains of Penicillium isolated from New Zealand cheddar cheese and received under the label of P. puberulum Bainier, Birkinshaw & Raistrick [1936] were led to examine biochemically certain strains in the P. terrestre Jensen series. These moulds, with the exception of one strain, when grown on a Raulin-Thom glucose medium, produced in fair quantity a hitherto undescribed metabolic product for which the name terrestric acid is proposed.
