Identify the bacteria based on the pictures and flow chart.

Answer 1

The images say that-

The bacteria is gram negative as it did not retain the purple stain as that of gram positive bacteria.

The aerotolerance test says that it is a facultative anaerobe because the growth is in the entire tube not only on the top.

So the organism is-

E.coli/ E. aerogenes/  P. stuartii /C. freundii
