Task: Answer Verification
Input (English): Question: Is biofilm formation by otopathogenic strains of Pseudomonas aeruginosa consistently inhibited by ethylenediaminetetraacetic acid?
Answer: Our hypothesis was disproven: EDTA tends to delay biofilm development, although it consistently inhibits planktonic growth. Because EDTA does not cause suppression of biofilm production in all isolates of OPPA, usefulness as an antimicrobial is questioned.
Output (English): no
