Abstract:A strain ofPseudomonas aeruginosa from soil produced large quantitaties of extracellular neutral proteinase and could utilize several organic substances as carbon and nitrogen sources for enzyme production. The growth media required the presence of a high amount of phosphate when glucose was the carbon source. The intermediates of citric-acid cycle acids supported the proteinase production more than any other carbon sources. However, complex nitrogenous substances supported enzyme production more efficiently. Higher concentration of casamino acids suppressed the proteinase synthesis.
