Result interpretation of Total Coliforms paddle tester
Answer
Total Coliforms will appear as pinkish, gray colonies on the light red medium of the Total Coliforms Paddle Tester (catalog number/order code 2610910). Colonies which appear colorless indicate the presence of non-lactose fermenting bacteria. Most gram-positive bacteria are inhibited.
