  • a The values are averages for triplicate samples; standard deviations are indicated in parentheses. The maximal bacterial OD600 was 0.70.

  • b The mineralization values are averages for duplicate samples; standard deviations are indicated in parentheses. The maximal bacterial OD560 for strains B2, B1, and NS2 were 1.8, 1.8, and 1.6, respectively. The yields of metabolites were calculated from data provided in reference 20.

  • c Biomass was not given. The yields of nitroso metabolites were estimated from values provided in reference 31.

  • d ND, no data available.
