1) general media like TSA allows growth of any bacteria, while selective/ differential media are used to select for specific species/ and differentiate among closely related species of bacteria. 2)hemolysis helps to detect bacteria that can produce enzymes to lyse blood cells. Different species of Streptococcus shows a different level of enzyme production, partial decomposition gives green color and complete decomposition of blood gives red color. 3) The methylene blue indicator is used to verify the anaerobic condition in the jar. The blue color must become colourless after incubation to confirm the absence of oxygen. The strip color was observed Blue thus indicating presence of oxygen. The organisms growing on the plate are aerobes and aerobes should not grow in anaerobe condition. 4) enteric bacteria are commonly found in feces and the UTI is caused by the infection of aerobic fecal flora.
