The dimorphic fungus Mucor racemosus was grown as a yeast in a chemostat. Cellular growth rates were varied over a fourfold range under an atmosphere of N2 and over an eightfold range under CO2. Under either atmosphere, an increase in the cellular growth rate resulted in increases in (i) the cellular ribosome concentration, (ii) the percentage of ribosomes active in protein synthesis, and (iii) the rate of polypeptide chain elongation. The rate of protein synthesis in this organism can therefore be regulated by adjustment of all of these mechanisms.
双态真菌总状毛霉在恒化器中作为酵母生长。在氮气气氛下，细胞生长速率在四倍范围内变化，在二氧化碳气氛下则在八倍范围内变化。在任何一种气氛下，细胞生长速率的增加都会导致以下方面的增加：（i）细胞核糖体浓度，（ii）活跃于蛋白质合成的核糖体百分比，以及（iii）多肽链延伸速率。因此，该生物体中的蛋白质合成速率可以通过调节所有这些机制来调控。
