Addition of oxygen-containing C1-compounds to chemostat cultures of GB 25 increases both the yield of biomass and the specific growth rate. At optimum concentrations the catalytic activity of these compounds increases with increasing growth rates. Their influence on maintenance coefficients and maximum yield coefficients decreases in the order CH3OH greater than CO2 greater than HCOOH greater than HCHO. This result together with spectrophotometric NADH determinations suggests that the NADH pool determines the balance between the assimilatory and oxidative utilization of formaldehyde.
向GB 25的恒化器培养物中添加含氧化合物C1可提高生物量产量和比生长速率。在最佳浓度下，这些化合物的催化活性随生长速率的增加而增加。它们对维持系数和最大产量系数的影响按CH3OH＞CO2＞HCOOH＞HCHO的顺序降低。这一结果与分光光度法测定的NADH一起表明，NADH库决定了甲醛同化利用和氧化利用之间的平衡。
