The stable L form of Agromyces ramosus reverted to a bacterial form when incubated in sterilized soil. The cellular and colonial morphology of this bacterial form resembled that of the original parent bacterial form. The two forms differed, however, in that the revertant maintained its bacterial form when transferred onto a low-salt (NaCl) medium but was virtually completely induced into the L-form state on a high-salt medium. The original parent bacterial form was not sensitive to salt. The possibility is discussed that an L-form interchanging with a bacterial-form cycle for this bacterium might occur naturally in soil. This cycle would be mediated by fluctuations in local salt concentrations in the soil.
在无菌土壤中培养时，分枝放线菌的稳定L型回复为细菌型。这种细菌型的细胞和菌落形态与原始亲本细菌型相似。然而，这两种形态的不同之处在于，回复突变体转移到低盐（NaCl）培养基上时保持细菌型，但在高盐培养基上几乎完全诱导为L型状态。原始亲本细菌型对盐不敏感。文中讨论了这种细菌的L型与细菌型循环相互转换可能在土壤中自然发生的可能性。这个循环将由土壤中局部盐浓度的波动介导。
