  My unknown identificationin appears metabolic green sheen on EMB, indole -,Lactose fermentation +,and convex dark pink growth on Mac, but H2S NEGTIVE, VP POSITIVE. I've made all the tests at least twice in same results. I infer that might be Citrobacter freundii, but I don't know why the H2S and VP test are opposite to Bergey's Mannual. Is my inference right? Or the unkown is more likely to be Escherichia coli? Help me please,THX.
