Metabolism of glycosides by Pseudomonas maltophilia.

Abstract

A study of the abilities of 23 strains of Pseudomonas maltophilia to hydrolyze synthetically-prepared and naturally-occurring glycosides is presented. Direct detection of liberated aglycones was used to determine hydrolysis of the five most-commonly-used glycosides (amygdalin, arbutin, esculin, ONPG (o-nitrophenyl-beta-d-galactoside), and salicin). The capabilities of the strain for acid production from 17 glycoside substrates were also determined using a medium designed to minimize the production of acid-neutralizing end-products from peptones.
