| 摘要: |
| 用溴化乙锭诱发质粒,溴化乙锭不同浓度对棒状杆菌基因组起不同作用,低浓度无作用;高浓度消除质粒;适中浓度能诱发质粒。本试验诱发出4种大小不同质粒,转种5代质粒消失。 |

| Abstract: |
| A review summarised the plasmids of nonpathogenic Corynebacterium.Corynebacterium pekingense AS 1.299 had plasmids,which could be induced by treatment of ethidium bromide (EB). Their molecular sizes were 36.2×106,15.2×106,13.0×106 and 9.8×106 respectively,compared with 8 known plasmids of E.coliv 517.AS 1.299 strain had no plasmids originally. These inducible plasmids disappeared spontaneously from the host after transfered to fresh media by the fifth time. |
