Abstract
A widely used method for quantifying swarming motility is the swarm plate assay. A significant increase in the motility halo size formed by Escherichia coli or Azospirillum brasilense was measured on Tween 80-containing agar relative to untreated agar. This improvement could benefit the identification of mutants in swarming motility.
摘要
一种广泛用于量化群体运动性的方法是群体平板试验。相对于未处理的琼脂，在含有吐温80的琼脂上测量到大肠杆菌或巴西固氮螺菌形成的运动晕圈大小显著增加。这一改进可能有助于群体运动性突变体的鉴定。
