Carbohydrate, fermentation of which can be detected by phenol red. Biochemical test of bacillus subtilis. Bacillus subtilis for my biochemical testing, had tube number four.
The Selection Process Was Started With A Methyl Red Test Which Led To The Conclusion.
It supports the growth of most organisms whether they are able to ferment sugar or not. The phenol red is the ph indicator and is initially neutral (ph 7). Bacillus subtilis originally was considered an aerobic bacterium, meaning that oxygen was required for formation of the bacterium.
