WebAeromonas is a Gram-Negative bacterium. It is consistent with the other test we have done, for example, growth on the Vancomycin, growth on the PEA, and the string test. With the similarities in the physiology and morphology, we can conclude that the DNA sequence was accurate, and the unknown bacteria is Aeromonas. WebThe genetic information of all cells resides in the sequence of nitrogenous bases in the extremely long molecules of DNA.
