Abstract

When ratios of the major polypeptides of the outer membrane isolated from cells of Escherichia coli B grown in minimal medium containing either a single amino acid or several amino acids were compared, no difference was observed. However, the ratio of these polypeptides in outer membrane material released into the medium during logarithmic phase growth on these two media was markedly different.

摘要

当比较从在含有单一氨基酸或几种氨基酸的基本培养基中生长的大肠杆菌B细胞分离出的外膜主要多肽的比例时,未观察到差异。然而,在这两种培养基上对数期生长期间释放到培养基中的外膜物质中这些多肽的比例明显不同。
