32株慢生根瘤菌的脂肪酸组成和多重耐药模式与两个主要的脱氧核糖核酸同源基团相关。I组的脂肪酸组成为：顺9酸1.3%，16：1C酸3.6%，16：0酸8.8%，环丙烷酸1.2%，18：1酸81.2%。组II含0.5%16：1C酸、11.1%16：0酸、0.8%17：0环丙酸、24.7%19：0环丙酸、62.3%18：1酸。I组菌株对利福平(500µg/ml)、四环素(100µg/ml)、链霉素(100µg/ml)、氯霉素(500µg/ml)、红霉素(250µg/ml)、羧苯西林(500µg/ml)和奈利地酸(50µg/ml)敏感，而II组菌株对这些抗生素耐药。两组均对甲氧苄氨嘧啶(50微克/毫升)和万古霉素(100微克/毫升)耐药。
The fatty acid compositions and multiple antibiotic resistance patterns of 32 strains of Bradyrhizobium japonicum correlated with two major deoxyribonucleic acid homology groups. In group I, the fatty acid composition was 1.3% 16:1 cis9 acid, 3.6% 16:1C acid, 8.8% 16:0 acid, 1.2% 19:0 cyclopropane acid, and 81.2% 18:1 acid. Group II contained 0.5% 16:1C acid, 11.1% 16:0 acid,k0.8% 17:0 cyclopropane acid, 24.7% 19:0 cyclopropane acid, and 62.3% 18:1 acid. Group I strains were susceptible to rifampin (500 .mu.g/ml), tetracycline (100 .mu.g/ml), streptomycin (100 .mu.g/ml), chloramphenicol (500 .mu.g/ml), erythromycin (250 .mu.g/ml), carbenicillin (500 .mu.g/ml), and nalidixic acid (50 .mu.g/ml), whereas group II strains were resistant to these antibiotics. Both groups were resistant to trimethoprim (50 .mu.g/ml) and vancomycin (100 .mu./ml).
