The effect of He-Ne laser radiation (lambda = 632.8 nm) on bacteriophage T4-Escherichia coli WP2 interactions was studied. Irradiation of bacteria having respiratory chain components as primary photoacceptors accelerated their division in a dose-dependent manner, but irradiation had no effect on the properties of the phage (measured as its ability to infect host cells). At the same time, exposure of bacteria to stimulating doses of He-Ne laser radiation (from 10(3) to 6 x 10(4) J/m2) increased their ability to promote the growth of unexposed phages. These results clearly indicate that low-power laser effects require primary photoacceptors (phage contains no chromophores for red light).
研究了氦氖激光辐射（波长λ = 632.8 nm）对噬菌体T4与大肠杆菌WP2相互作用的影响。以呼吸链成分作为主要光受体的细菌受到辐射后，其分裂以剂量依赖的方式加速，但辐射对噬菌体的特性（以其感染宿主细胞的能力衡量）没有影响。同时，将细菌暴露于刺激剂量的氦氖激光辐射（从10³至6×10⁴ J/m²）下，会增强它们促进未暴露噬菌体生长的能力。这些结果清楚地表明，低功率激光效应需要主要光受体（噬菌体不含用于红光的发色团）。
