摘要

1.1. 以有无青霉素条件下生长的炭疽芽孢杆菌V1B-189细胞壁粘肽为原料制备炭疽芽孢杆菌细胞壁粘肽。这两种类型都含有一种不寻常的内膜。对它们进行了还原糖、氨基糖和氨基酸的分析。两种类型均以1:1.5:1.3.3摩尔比的谷氨酸、丙氨酸和二氨基戊酸为主要氨基酸。青霉素没有改变不同细胞壁成分的相对量,但降低了单位重量黏肽中所有成分的重量。

The chemistry of the cell walls of Bacillus anthracis: the effect of penicillin

  • 1.

    1. Cell wall mucopeptide of Bacillus anthracis, strain V1B-189 was prepared from cells grown in the presence and absence of penicillin. Both types contain an unusual inner membrane.

  • 2.

    2. These were analysed for reducing sugars, amino sugars and amino acids. Both types contained glutamic acid, alanine and diaminopimelic acid as the principle amino acids in the mole ratios of 1:1.5:1.

  • 3.

    3. Penicillin did not change the relative amounts of the different cell wall constituents but it did reduce the weight of all constituents per unit weight of mucopeptide.
