比较了从不同来源的木麻黄根瘤中分离得到的三株弗兰克氏菌（Ｆｒａｎｋｉａ）在两种浓度不同碳源培养基中的生长差异，结果表明：供试菌株在以丙酮酸钠为唯一碳源时生长最好，其生长量为其它碳源的１．３～４７．７倍；最适合的碳源浓度为０．２３ｇＣ／Ｌ在三种不同的Ｆｒａｎｋｉａ菌培养方式中，通入无菌空气及发酵培养较静置培养能显著地提高弗兰克氏菌的生长量。同时还探讨了弗兰克氏菌的发酵条件。
The differences in the growth of three Frankia strains isolated from different origins of Casuarina equiseti were compared in two different carbon source cultures. The results showed that when the test strains were treated with sodium pyruvate as sole carbon source When the best growth, the growth of other carbon sources of 1.3 to 47.7 times; the most suitable carbon source concentration of 0.23gC / L in three different Frankia bacteria culture mode, the introduction of sterile air And fermentation culture more stationary culture can significantly improve the growth of Franklin bacteria. The fermentation conditions of Frankella were also discussed.
