IDENTIFICATION OF A GROWTH FACTOR IN TOMATO JUICE FOR A NEWLY ISOLATED STRAIN OF PEDIOCOCCUS CEREVISIAE

Abstract

A newly isolated strain (L‐73) of Pediococcus cerevisiae showed very slow growth in the Nakagawa medium which has been routinely used for the detection of lactic acid bacteria in the brewery. When the Nakagawa medium was enriched with 2% tomato juice extract or when the medium was prepared with the use of unhopped beer, strain L‐73 showed good growth. The growth‐stimulating factor in tomato juice was purified by chromatography on a charcoal column and it was finally identified by bio‐autography as 4′‐0‐(β‐D‐glucopyranosyl)‐D‐pantothenic acid. 1975 The Institute of Brewing & Distilling
