Characterization of Paenibacillus strains. A, Representative results are shown for: production of protease on Casein-Yeast extract agar (CYEA) plates with 7% skim milk after 72 hr; B, Cellulase production on CYEA plates with 1% carboxymethyl cellulose after 72 hr, followed by flooding with Congo red solution (1 mg/mL); C, Siderophore production in Chrome azurol S agar plates after seven days; tricalcium phosphate solubilization in Pikovskaya's phosphate agar medium (D) and National Botanical Research Institute's Phosphate agar medium (E) after 14 days; F, Hydrocyanic acid production on tryptic soy agar with glycine (4.4 g/L) after four days, detected using filter paper treated with picric acid solution.
