Popis:	In an attempt to find an alternative to 1-naphthol for use in the Voges-Proskauer (VP) test, a number of aromatic or heterocyclic compounds have been examined. Of these, anthrone tautomeric with 9-anthranol proved to be of considerable interest. When employed in place of 1-naphthol in the Barritt modification, intense blue-green colorations were exhibited by VP-positive enterobacteriaceae. A similar result was obtained using dilute solutions of acetoin. VP-negative organisms yielded a yellow colour due to the alkaline anthrone. The use of pyruvate further improved the sensitivity and discrimination of the test.
