Abstract
Microcosm dental plaques were grown from an inoculum of human saliva in a constant-depth film fermentor. The inoculum contained four tetracycline-resistant streptococcal species, each of which contained a Tn916-like element. This element was shown to transfer to other streptococci both in filter-mating experiments and within the biofilms in the fermentor.
摘要
在恒深膜发酵罐中，以人唾液接种物培养微观世界牙菌斑。该接种物包含四种耐四环素的链球菌属菌种，每种菌种都含有一个类Tn916元件。在滤膜杂交实验以及发酵罐生物膜内，该元件均能转移至其他链球菌。
