鲁氏毛霉的营养发育可能遵循两种形态发生模式（霉菌-酵母二型性）之一，这取决于培养的气氛。在空气或N2下，丝状（霉菌样）生长发育，通常随后菌丝分裂成球形细胞（节孢子）。将CO2引入厌氧气氛中诱导球形出芽酵母样细胞的发育。在厌氧条件下，0.3个大气压或更高的PCO 2产生了纯粹的酵母样发育。氧气的存在消除了CO2的影响。在萌发时，孢子直接引起两种类型的营养发育，这取决于孵化的气氛。CO_2对5株M. rouxii。并且在大多数测试的毛霉属物种中。M.最精细的然而，不需要二氧化碳;它在厌氧条件下以酵母样形式发展。根霉菌株在CO2条件下生长，但只形成丝状菌丝体。Mucoiales的其他属的成员不能在CO2的气氛下生长。
Vegetative development of Mucor rouxii may follow either one of two patterns of morphogenesis (mold-yeast dimorphism), depending on the atmosphere of incubation. Under air or N2, a filamentous (moldlike) growth developed, commonly followed by fragmentation of hyphae into spherical cells (arthrospores). Introduction of CO2 into an anaerobic atmosphere induced development of spherical, budding yeastlike cells. Anaerobically, a PCO2 of 0.3 atm or higher produced a purely yeastlike development. Presence of oxygen annulled the effect of CO2. On germination, spores gave rise directly to either type of vegetative development, depending on the atmosphere of incubation. Induction of yeastlike development by CO2 occurred in five strains of M. rouxii. and in most species of Mucor tested. M. subtilissimus. however, did not require CO2; it developed in the yeastlike form under anaerobic conditions. Strains of Rhizopus grew under CO2, but developed only filamentous mycelium. Members of other genera of Mucoiales were unable to grow under an atmosphere of CO2.
