Question:

Various streptococci and lactobacilli were traditionally grouped together as lactic acid bacteria because of their characteristic fermentation. Most of them were found to have a DNA Guanine plus Cystosine (G + C) content of approximately 40%, but one of them had a G + C content of 58%. Should this organism remain in the same genus as the rest of the bacterial species? Explain your answer.
