WebBiochemical tests are among the most important methods for microbial identification. Routine biochemical tests include tests for carbohydrate fermentation (Figure 2.18(A)), … WebThe test directly measures the production of nitrite from nitrate either by the organism (a positive test) or by zinc (a negative test). The test works on the basis of a chemical reaction between nitrite, sulfanilic acid and alpha-napthylamine which forms a bright red compound. If no color develops after the addition of zinc the test is positive.
