Fig 1.  Two pathways for glucose degradation.

Fig 2.  Reactions in oxidative fermentation media.
Left to right: Fermenter: open and sealed tubes positive for
acid production; nonfermenter: open tube positive for acid
production, sealed tube negative for acid production;
nonfermenter/nonoxidizer: open and sealed tubes negative
for acid production.

Fig 3.  Triple sugar iron agar reactions. Left to right:
Tube 1, A/A gas; tube 2, A/A H2S; tube 3, K/A; tube 4, K/A
H2S; tube 5, K/K.

Fig 4.  Ortho-nitrophenyl β-D-galactopyranoside test.

 

Fig 5. A, The methyl red–Voges-Proskauer test is inoculated and incubated

overnight. Then it is split equally into two parts: one part for the methyl red test, the

other for the Voges-Proskauer test. B, Methyl red test. C, Voges-Proskauer test.

Fig 6.  Lysine iron agar reactions. Left to right: K/K
(positive decarboxylation without H2S), K/A H2S (negative
decarboxylation with H2S), K/K H2S (positive decarboxylation
with H2S), R/Y (negative decarboxylation, positive
deamination without H2S).
