This strain V1were able to hydrolyze sucrose to produce dextran, was able to hydrolyze esculin catalyzed by a [beta]-glucosidase through the presence of esculinase which degrades it to glucose and esculinite [24, 32].

These isolates also showed positive indole production, glucose aicidification, arginine dihydrolase, esculin hydrolysis, gelatin hydrolysis, 4-nitrophenyl-ssD-galactopyranoside, Glucose assimilation, arabinose assimilation, mannose assimilation, mannitol assimilation, N-acetyl- glucoseamine, maltose glucoseamine, gluconate glucoseamine, caprate glucoseamine, adipate glucoseamine, malate glucoseamine and cytochrome oxidase.

Finally, an additional analysis towards ecYBDN suggested that YBDN genes were common in genomes of different bacterial organisms and exhibited a conserved molecular function to hydrolyze disaccharide, Esculin.
With the objective of validation, the reactions in malonate, esculin and citrate media and growth in Mueller Hinton medium which did not include blood were evaluated.
The OmniLog also does not have crucial biochemical tests such as urea and esculin, which could be necessary to differentiate between species.
2013), the occurrence of cumarins content in Glucevia[R], including fraxin, fraxetin, esculin, esculetin, cichoriin, scopolin and fraxidin glucoside was quantified.
The selected isolates were investigated for various biochemical and physiological characteristics including, melanin production, utilization of nine different sugars as carbon source, formation of organic acids, utilization of organic acids and oxalate, hydrolysis of esculin, urease, amylase, lipase, hemolysin, tyrosine hydrolysis, gelatinase and indole production.
