• For some purposes, certain bacteria are able to hydrolyze aesculin.
• A plate containing aesculin will fluoresce a pale blue under UV radiation.
• Aesculin, the glucoside of aesculetin, will nm ).
• The hydrolysis of aesculin results in loss of this fluorescence.
• The bile aesculin agar is streaked and incubated at 37 癈 for 24 hours.
• Aesculin will nm ) : hydrolysis of aesculin results in loss of this fluorescence.

• This species is able to hydrolyse aesculin.
• It hydrolyses casein and gelatin but not Tween 80, starch, lecithin, aesculin or tyrosine.
• The USDA notes that the toxicity is due to saponin aescin and glucoside aesculin, with alkaloids possibly contributing.
• It was first isolated from animals in Japan and Brazil . " M . Nana " resembles " hydrolyse aesculin.
• Other ingredients are aesculetin, aesculin, cichoriin, umbelliferone, scopoletin, 6, 7-dihydrocoumarin, and further sesquiterpene lactones and their glycosides.
• Aesculin is also used in a microbiology laboratory to aid in the identification of bacterial species ( especially " Enterococci " and Listeria ).
• This bacterium produces urease, alkaline phosphatase, pyrrolidonyl arylamidase, beta-galactosidase, and beta-glucuronidase, and hydrolyses aesculin and Tween 80.
• The four serogroups of hemolytic streptococci identified in domesticated dogs belong to Lancefield groups A, C, E, and G . Of these four, " S . canis " is described as belonging to group G due to it being a beta-hemolytic and aesculin-negative " Streptococcus " that is able to ferment lactose.
