Question

need a dichotomous key starting with hydrolysis

Unknown Gram Rod Gram+ Cocous Lactose+ Lactose Coagulase Coagulase + E coll S aureus P. aeruginoss S. epldermidis Practice Dichotomous Key Using the information on the following Matrix Chart, createa dichotomous key whose format is similar to the example given earlier. Your first step is to identify a test that comes as close as possible to separating the seven bacteria on the chart into two groups. For each of the two groups, chose an appropriate test that would further subdivide each group etc. until all seven bacteria are separated from one another. Have your instructor check your progress to be sure you are on the right track. You should be able to use a key such as this to identify any of the bacteria we have used in lab this quarter. 6.50% Optochin Bile solubility Streptococcus Hemolysis Bacitracin CAMP reaction SXT Bile Esculin NaCl Negative Negative Negative Negative Susceptible Negative R S. pyogenes beta Positive R Negative Postitive Negative Negative S. agalactiae beta Resistant Negative Negative Negative Negative Resistant Negative S S.equi beta Positive Positive Negative Negative Resistant Negative R |alpha S. faecalis Postitive Negative Negative Negative Resistant Negative S alpha S. bovis Negative Negative Negative Negative Negative S Resistant alpha Viridans Positive Resistant Netative SNegative Negative Positive Pneumococci alpha 17.4

starting with hydrolysis make a dichotomous key using bacitracin, CAMP, sxt, bile esculin, optochin, bile solubility
