The frequency of conjugation during filter mating of pneumococcus was increased 10- to 100-fold when the filter was embedded in agar during incubation instead of being on the surface. The major effect was not due to protection from oxygen. The factor of increase was similar for transfer of plasmids and of chromosomal insertions of drug resistance elements.
在肺炎球菌滤膜交配过程中,当滤膜在培养期间嵌入琼脂中而非置于表面时,接合频率提高了10至100倍。主要影响并非由于免受氧气影响。质粒转移和耐药元件的染色体插入转移的增加因子相似。
