Different biochemical tests for the identification of Bacilli species. The figure was adapted and redrawn after modifications from T.W. Fisher and Garczynski [23]. Some details of the tests presented include VP (Voges–Proskauer test (Barritt’s method)), Gelatin (proteolysis of gelatin), ADH (presence of the amino acid arginine dihydrolase), Glucose (fermentation) and Mannitol (fermentation); Starch (hydrolysis), Nitrate (nitrate reduction to nitrite), and Urea (Urease test).
