a
Kinetic values are the maximum zero-order methane uptake rate (Vmax(app) [nanomoles of CH4 per gram of dry weight per hour]), the apparent Michaelis-Menten kinetic constant (Km(app) [ppmv of CH4]), which was calculated from Vmax(app)/a0s, and the specific affinity (a0s [milliliters of gas per gram of dry weight per hour]). a0s is a first-order rate constant. The unit milliliters refers not to milliliters of CH4 but rather to standardization to a 1-ml total gas volume. To calculate rates of atmospheric methane uptake at 25°C multiply a0s by the mixing ratio of methane in the atmosphere (1.7 ppmv of CH4 = 0.071 nmol of CH4 ml−1).
