The Enterоtube II аllоws micrоbiologists to do multiple biochemicаl tests аt once to identify bacteria. Consider the image below. The tube on top shows the Entertube II uninoculated tube, while the tube on the bottom of the image shows the results after inoculation and incubation. Use the table below to determine the five-digit number obtained for the tube at the bottom. Glucose + Gas [option1] Lysine + Ornithine + H2S [option2] Indole + Adonitol + Lactose [option3] Arabinose + Sorbitol + Dulcitol [option4] Phenylalanine + Urea + Citrate [option5] Table 1. Values to be assigned for each positive test. Test Score Glucose 2 Gas 1 Lysine 4 Ornithine 2 H2S 1 Indole 4 Adonitol 2 Lactose 1 Arabinose 4 Sorbitol 2 Dulcitol 1 Phenylalanine 4 Urea 2 Citrate 1
