- Describe the appearance of an S. agalactiae colony grown on blood agar. Describe how that colony would differ in appearance from a colony of S. pyogenes.1) would you describe the contents of the soil-inoculated broth as being a “pure culture”? Why or why not? 2) How did the uninoculated broth differ in appearance from the broths inoculated with E. Coli and M. Luteus? And then how could you tell if a supposedly sterile, uninoculated broth was contaminated? Please explain in detail and highlight the important parts cuz I am confused and need help! ThanksCould you explain the difference ( and possibly show the difference) between a growth on Agar slants and Growth in broths? Next, could you describe what E. Coli, M. Luteus, and an uninoculated growth should look like on both agar slants and broths? Much thanks! I am a bit confused
