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.

Answer 1

Answer:

Yes! it should remain in the same genus...

Explanation:

Although most of them have a 40% GC content but some species of for example lactobaccilus may have more GC than that e.g., Lactobacillus delbrueckii has a GC content of 62% while Lactobacillus fermentum has a GC content of 63% and both of them also belong to the same genus. So, it should remain in same Genus classification.
