  1. ameasurements are made on solid medium with no agitation at RT.
  2. bmeasurements are made on liquid medium with agitation at RT.
  3. cThe coefficients are estimated considering a confidence level of 95% that the real value is in that range.
  4. dmutant strain does not show spectral response.
