General description

D-Melezitose is a carbon substrate.


D-Melezitose has been used in a study to assess the identification of clinical isolates of indole-positive and indole-negative Klebsiella spp. It has also been used in a study to investigate new epidemiologic markers of Klebsiella oxytoca strains.

Conventional methods usually fail to identify Klebsiella planticola and Klebsiella terrigena, which represent up to 19% of clinical Klebsiella isolates. By combining four carbon substrate assimilation tests and two conventional tests, the method identified these species with a specificity and...

Biochemical methods employed to classify bacterial species have limitations and may have contributed to the taxonomic complexity recently reported for the genus Klebsiella. The objective of the present study was to apply a simple biochemical test panel to classify a...

In addition to capsular antigen typing and biotyping (sorbose, d-tartrate, dulcitol), the epidemiology of Klebsiella oxytoca can be improved by new biochemical characterization. The authors propose to determine tetrathionate-reductase activity, D-melezitose fermentation and brown pigment production onto a mineral gluconate-ferric...

A rational optimization for the synthesis of galacto-oligosaccharides (GOS) from lactose catalyzed by β-galactosidase from Aspergillus aculeatus, included in the commercial product Pectinex Ultra SP-L, has been performed by using experimental design and surface response methodology. This accurate tool optimized...
