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. WebThis test is used to identify bacteria that can hydrolyze starch (amylose and amylopectin) using the enzymes a-amylase and oligo-1,6-glucosidase. Often used to differentiate species from the genera Clostridium and Bacillus. Because of the large size of amylose and amylopectin molecules, these organisms can not pass through the bacterial cell wall.
