A new, generally applicable, thermodynamically based method is proposed to provide an estimation of the biomass yield on arbitrary organic and inorganic substrates. Aerobic, anaerobic, denitrifying growth systems with and without reversed electrontransport are covered. The biomass yield can be estimated with only 15% error in a very wide range of microbial growth systems and biomass yields (0.01-0.80 C-mol/(C)-mol). This method is based on the use of 'Gibbs energy dissipated per C-mol produced biomass' (designated as Ds01/rAx) as the central parameter. Moreover the insufficiency of other methods based on YATP, YAve, eta o, YC and enthalpy or Gibbs energy efficiencies is shortly discussed. Also it appeared to be possible to understand the obtained correlation of Ds01/rAx in general biochemical terms.
提出了一种新的、普遍适用的、基于热力学的方法，用于估算在任意有机和无机底物上的生物量产量。该方法涵盖了有氧、厌氧、反硝化生长系统，包括有和没有逆向电子传递的情况。在非常广泛的微生物生长系统和生物量产量范围（0.01 - 0.80 C - mol/(C)-mol）内，生物量产量的估算误差仅为15%。该方法以“每C - mol产生的生物量所耗散的吉布斯能量”（表示为Ds01/rAx）作为核心参数。此外，还简要讨论了其他基于YATP、YAve、eta o、YC以及焓或吉布斯能量效率的方法的不足之处。而且，从一般生化角度理解所得到的Ds01/rAx的相关性似乎也是可能的。
