We developed an efficient polyethylene glycol-mediated spheroplast transfection method for the extremely halophilic archaebacterium Halobacterium halobium. The 59-kilobase-pair linear phage phi H DNA molecule routinely produced between 5 X 10(6) and 2 X 10(7) transfectants per microgram of DNA. Between 0.5 and 1% of spheroplasts were transfected per microgram of luminal diameter H DNA. Under our conditions, survival and regeneration of H. halobium spheroplasts were also quite efficient, suggesting that this method will be useful for introducing other DNAs into these bacteria.
我们为极端嗜盐古细菌嗜盐栖热菌开发了一种高效的聚乙二醇介导的原生质球转染方法。59千碱基对的线性噬菌体φH DNA分子通常每微克DNA能产生5×10⁶至2×10⁷个转染子。每微克腔直径H DNA能转染0.5%至1%的原生质球。在我们的条件下,嗜盐栖热菌原生质球的存活和再生效率也相当高,这表明该方法将有助于将其他DNA导入这些细菌。
