Studies in the biochemistry of micro-organisms

Abstract
P. stipitatum when grown on Czapek-Dox 5% glucose soln. gives rise to a new mould metabolic product, stipitatic acid, C8H6O5, m.p. 302-304[degree] (decomp.). Its chem. properties and derivatives are descr. The acid apparently belongs to a class of compounds not previously encountered among mould metabolic products, except possibly puberulic acid from P. puberulum [see B. A. 8(7): entry 15207].
