A Common Intestinal Flora Isolate, Demonstrates Alpha Hemolysis on Blood Agar Growth Medium

This organism is a common inhabitant of intestinal flora, and can be a major cause of urinary tract infection.

This species of Rhodospirillum is commonly isolated from stagnant water and mud. It is especially interesting because it produces a red pigment and is also capable of photosynthesis.

This organism is commonly isolated from soil, and depending upon the temperature of its environment, can produce a distinctive red pigment.
