General description

D-Melezitose is a carbon substrate.

Application

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

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

Efficient nutrient acquisition in the human gut is essential for microbial persistence. Although polysaccharides have been well-studied nutrients for the gut microbiome, other resources such as nucleic acids and nucleosides are less studied. We describe several ribose-utilization systems (RUSs) that
