The characteristics of ten N2(C2H2)-fixing Bacillus strains, isolated from Egyptian soils, were investigated. The isolates were not completely identical to any of the described species in the 8th Edition of BERGEY's Manual. However, two strains were closely related to B. cereus, five strains were tentatively characterized as B. licheniformis and three strains with swollen sporangia and thick-walled endospores shared their main characteristics with B. circulans. A comparison between these bacilli and other known nitrogen-fixing Bacillus species revealed major differences in culture characteristics and C2H2-reducing activities. This suggests that the Bacillus isolates described here are new nitrogen-fixing bacteria.
对从埃及土壤中分离出的10株固定N2（C2H2）的芽孢杆菌菌株的特性进行了研究。这些分离株与《伯杰氏手册》第8版中描述的任何物种都不完全相同。然而，有两株菌株与蜡样芽孢杆菌密切相关，五株菌株暂定为地衣芽孢杆菌，三株具有膨大孢子囊和厚壁内生孢子的菌株与环状芽孢杆菌具有共同的主要特征。这些芽孢杆菌与其他已知的固氮芽孢杆菌物种之间的比较揭示了培养特性和C2H2还原活性的主要差异。这表明这里描述的芽孢杆菌分离株是新的固氮细菌。
