Abstract

Diquat (2 x 10(-4)m) inhibited both aerobic and anaerobic growth of Rhodospirillum rubrum. With photosynthetic cultures, diquat affected the synthesis of bacteriochlorophyll more readily than cell mass (turbidity). Diquat retarded the synthesis of bacteriochlorophyll and some protein more readily than that of other cellular constituents such as ribonucleic acid, deoxyribonucleic acid, and cell mass. With cells deficient in phosphate, diquat inhibited the uptake-conversion of inorganic phosphate completely only when 3-(3,4-dichlorophenyl)-1,1'-dimethyl urea and ascorbate were also present.

摘要

敌草快(2×10⁻⁴摩尔)抑制了深红红螺菌的需氧和厌氧生长。对于光合培养物,敌草快对细菌叶绿素合成的影响比对细胞质量(浊度)的影响更容易。敌草快比其他细胞成分如核糖核酸、脱氧核糖核酸和细胞质量更易延迟细菌叶绿素和一些蛋白质的合成。对于缺乏磷酸盐的细胞,只有当同时存在3-(3,4-二氯苯基)-1,1'-二甲基脲和抗坏血酸盐时,敌草快才会完全抑制无机磷酸盐的吸收转化。
