Aesculin is incorporated into agar with ferric citrate and bile salts (bile aesculin agar). (wikipedia.org)
The bile aesculin agar is streaked and incubated at 37 °C (99 °F) for 24 hours. (wikipedia.org)
An inoculum from a pure culture is transferred aseptically to a tube of OF glucose medium with oil overlay The agar is stabbed through the oil to "plant" the bacteria in the butt of the tube. (vumicro.com)
Salts4
They are facultative anaerobes that grow at temperatures ranging from 10 to 45 o C, with optimum growth at 35 o C. They grow in media containing 6.5% NaCl and hydrolyze esculin in presence of 40% bile salts (bile -esculin medium). (microbesinfo.com)
Crystal violet, bile salts and neutral red are inhibitory agents. (umd.edu)
The medium contains bile salts and crystal violet, which inhibit the growth of Gram-positive bacteria. (timesofpharma.com)
Group D Streptococci are capable of hydrolyzing Aesculin to glucose and aglycone 6-7 dihydroxycumarin: The aglycone reacts with the iron salts in the medium giving them a black coloring. (hylabs.co.il)
Hydrolyze esculin1
tests ability of the organism to hydrolyze esculin to esculetin. (umd.edu)
Group D Streptococci1
In fact, all strains of Group D Streptococci hydrolyze æsculin in 40% bile. (wikipedia.org)
A positive result for fermentation of glucose is indicated by the medium turning yellow. (vumicro.com)
Nearly all strains are homofermentative, gas is not produced, and lactic acid is the end product of glucose fermentation. (microbesinfo.com)
Zymase is a complex of enzymes found in yeast cells that catalyze the conversion of sugars, such as glucose, into alcohol (ethanol) and carbon dioxide during the process of alcoholic fermentation. (labtestsguide.com)
Lactose1
The isolate was motile, catalase positive, oxidase negative, and it fermented glucose and lactose. (cdc.gov)
Nutrient1
This consists of a nutrient medium to which 1% glucose has been added. (vumicro.com)
Aesculin1
Aesculin, also called æsculin or esculin, is a coumarin glucoside that naturally occurs in the trees horse chestnut (Aesculus hippocastanum), California buckeye (Aesculus californica), prickly box (Bursaria spinosa), and daphnin (the dark green resin of Daphne mezereum). (wikipedia.org)

Organisms1
When bile flow is obstructed, colonic organisms, including E coli, colonize the jejunum and duodenum. (medscape.com)
Oxygen1
Two tubes of OF glucose medium are used, one of which is covered with a layer of sterile mineral oil as an oxygen barrier. (vumicro.com)
Inclusion of starch makes it a rich medium for those bacteria possessing the enzyme alpha-amylase , which breaks starch down to its component glucose molecules. (vumicro.com)
Test1
This test provides insight into the ability of the bacterium to use glucose by both methods. (vumicro.com)
Broth1
The same procedure was repeated for all the tubes while at the same time avoiding the Durham tube when the Glucose broth is being inoculated. (topessaywriting.org)
Sucrose1
Similarly, TCPG could inhibit the uptake and phloem transport of exogenous sinigrin by Arabidopsis thaliana (L.) Heynh leaf tissues, while not affecting that of esculin (a fluorescent surrogate for sucrose). (bvsalud.org)
Strains2
In fact, all strains of Group D Streptococci hydrolyze æsculin in 40% bile. (wikipedia.org)
f All strains of S. bovis and approximately 10% of viridans streptococci are bile-esculin positive. (cdc.gov)
Aesculin, also called æsculin or esculin, is a coumarin glucoside that naturally occurs in the trees horse chestnut (Aesculus hippocastanum), California buckeye (Aesculus californica), prickly box (Bursaria spinosa), and daphnin (the dark green resin of Daphne mezereum). (wikipedia.org)
Medium2
An important component of the medium is a modest amount of glucose, necessary for the process to proceed. (vumicro.com)
Bile Aesculin Medium is generally used for the differentiation and presumptive identification of Group D streptococci (enterococci). (eolabs.com)
