The paper describes a number of tests for the rapid detection of glycosidases including alpha-glucosidase, beta-glucosidase, beta-glucuronidase, beta-xylosidase and alpha-fucosidase. The methods use heavy suspensions of viable but non-multiplying bacteria in a buffered solution of a chromogenic substrate. The results of the tests are readable within 4 h. The application of these tests to a collection of 633 strains of Enterobacteriaceae and Vibrionaceae demonstrates that some of the tests may be valuable additions to the present tests available for the identification of bacteria belonging to these families. beta-glucuronidase activity was observed only in strains of the Escherichia-Shigella group. 97 per cent of the Escherichia strains possessed beta-glucuronidase activity. beta-xylosidase activity was almost completely restricted to strains of the Klebsiella-Enterobacter group in addition to Yersinia strains. None of the strains possessed alpha-fucosidase activity.

Periplasmic oligopeptide binding protein (OppA) is part of a multimeric cytoplasmic membrane protein complex, whose function is known as peptide transporters found in Gram-negative bacteria. A chaperone-like activity has been found for the OppA from Yersinia pseudotuberculosis, using biochemical experiments. Through computational analysis, we selected two amino acid residues (R41 and D42) that probably are involved in the chaperone-like activity. Our results to corroborate how OppA assists refolding and renaturation of lactate dehydrogenase and alpha-glucosidase denatured enzymes.
