放线菌中的土壤细菌Frankia能够在多种放线菌根植物上形成固定n2的共生根瘤，在纯培养中生长时具有几种形态形式。新鲜水合制剂对木麻黄幼苗在不同稀释度下均有侵染作用。干燥的菌丝没有感染能力，而干燥的孢子仍然具有感染性，尽管水平有所降低。根据最可能数统计，孢子悬浮液的感染性比菌丝高3个数量级。
The soil bacterium Frankia of the Actinomycetales, capable of forming N2-fixing symbiotic root nodules on a diverse array of actinorhizal plants, has several morphological forms when grown in pure culture. Fresh hydrated preparations of whole cells, hyphae, and spores were all infective on seedlings of Casuarina at different dilutions. Desiccated hyphae showed no infection capacity, while desiccated spores remained infective, although at a reduced level. On the basis of most-probable-number statistics, spore suspensions were 3 orders of magnitude more infective than hyphae.
