An indirect approach to quantification of the fibrolytic anaerobic fungi in the rumen is described. A mathematical model of the life cycle of anaerobic fungi, based upon observations of the life histories and growth kinetics of these organisms in vitro and in vivo, is constructed and solved in the steady-state to determine the population of particle-attached (substrate-associated) fungal thalli from the concentration of free-swimming zoospores in rumen liquid. The values obtained are broadly consistent with ruminal observations and with observations on faecal populations, which assume that a significant proportion of fungi leaving the rumen (as cysts or spores) can ultimately be accounted for in the faeces.
本文描述了一种间接定量瘤胃中纤维分解厌氧真菌的方法。基于对这些生物体在体外和体内的生活史及生长动力学的观察，构建了厌氧真菌生命周期的数学模型，并在稳态下求解，以根据瘤胃液中自由游动的游动孢子浓度确定附着在颗粒上（与底物相关）的真菌菌体数量。所得值与瘤胃观察结果以及粪便菌群观察结果大致一致，后者假定离开瘤胃的大部分真菌（以囊肿或孢子形式）最终可在粪便中找到。
