26) S. typhimirium releases H2S gas. ( Right)
SIM stands for sulphur indole motility medium. It is used for determining sulphur reducing bacteria, indole producing and motile bacteria. The blue color in the media indicates that sulphir is reduced and H2S gas is evolved.
-----
27) E. coli is positive for indole test. (Left)
The tryptohan media is added in the media. The tryptophanase enzyme is released from the bacteria and breaks down tryptophan into indole. The layer is found above the test tube. It is found in the E.coli test tube.
