Which of the following statements is incorrect? (A) Pathogenic bacteria cause 90 % of human diseases. (B) A large number of antibiotics are produced by actinomycetes (e.g., Streptomyces), which are a class of fungi. (C) N2-fixing bacteria pick up free N2 from soil atmosphere and convert it into nitrogenous compounds. (D) Archaebacteria differ from other bacteria in having a different cell wall structure and this feature is responsible for their survival in extreme conditions
