There were differences in the way the lysogenic strain N of B. mycoides and the parent indicator strain grew on nutrient agar and in nutrient broth. 1. On agar, the indicator culture traveled more quickly over the agar surface than the phage-carrying strain; the total extent of spread was greater. 2. In broth, the indicator strain grew diffusely throughout the liquid, the lysogenic cells in clumps. The virus-infected strain appeared to grow more slowly. This may reflect (a) the effect of aggregation on the generation time of the lysogenic strain, (b) an active lytic process in the lysogenic population which is further enhanced by the effect of clump formation on the environment of the cell.
蕈状芽孢杆菌的溶原性菌株N和亲本指示菌株在营养琼脂和营养肉汤中的生长方式存在差异。1. 在琼脂上,指示培养物在琼脂表面上的移动速度比携带噬菌体的菌株更快;扩散的总范围更大。2. 在肉汤中,指示菌株在整个液体中呈弥散生长,溶原性细胞聚集成团。病毒感染的菌株似乎生长得更慢。这可能反映了(a)聚集对溶原性菌株世代时间的影响,(b)溶原性群体中的活跃裂解过程,而细胞团形成对细胞环境的影响进一步增强了这一过程。
