摘要：
Growth conditions are described for optimum production of extracellular protease in batch cultures of the soft rot pathogen Erwinia carotovora subsp. carotovora. This protease was inhibited by approximately 96% by 1 mmol/1 EDTA and by 55–6% by 10 mmol/l cysteine thereby classifying it as a metalloprotease. It was not inhibited by a chymotrypsin inhibitor extracted from potato tubers. This evidence suggests that the potato chymotrypsin inhibitor is not associated with resistance of potatoes to E. carotovora subsp. carotovora. Copyright © 1990, Wiley Blackwell. All rights reserved
