And chewing a conker - or its shell - can release a potentially fatal toxin called aesculin which is found in all parts of the horse chestnut tree.
An aliquot of the broth was plated onto blood agar plates and incubated in a C[O.sub.2] incubator at 35[degrees]C overnight, and a bile aesculin agar was inoculated.

Arginine dihydrolase agar and Aesculin Azide agar (Merck, Germany) were employed to perform the hydrolysis tests.
The isolates were examined for gram reaction, catalase, oxidase, ultraviolet fluorescence, argenin dihydrolase, levan production, gelatin liquefaction, aesculin hydrolysis, hypersensitive reaction on tobacco leaves and pectolytic capability (Schaad et al., 2001).
Samples were plated onto Sheep blood agar (5%>), MacConkey agar and Bile Aesculin agar.
Catalase-negative organisms were tested on both bile aesculin plates (Diagnostic Media Products, SA) and with the PYR 50 test (Remel, USA) to differentiate between Streptococci and Enterococci.
For secondary identification of the isolates to the species level, different biochemical tests (oxidation fermentation test, Mannitol and salicin sugar fermentation, aesculin hydrolysis, and CAMP test) were done based on the genus ofbacteria to be identified [10].
Some of the coumarins, such as aesculetin, aesculin, and fraxin, also possess antioxidant activity.
