Numerous studies have been conducted to evaluate the effect of phenethyl alcohol on excision repair of DNA damage induced by ultraviolet radiation (UV) in non-standard strains. When solutions (0.2 and 0.4%) of phenethyl alcohol were incubated with UV-damaged strains H/r 30 and B (wild-type), excision repair of membrane-associated DNA was inhibited, as measured by a decrease in liquid holding recovery and a decrease in the removal of thymine dimers. The authors hypothesized that excision repair may require that DNA is bound to the cell membrane, and the test article may have inhibited that binding (Tachibana & Yonei, 1985). Similar results were obtained in an earlier study, in which it was shown that 0.05–0.5% solutions of phenethyl alcohol caused detachment of DNA from the DNA–membrane complex in B cells. The effect was concentration-dependent. Similar results were obtained with NG30 (rec A mutant) (Tachibana et al., 1982). In a related study, phenethyl alcohol inhibited the removal of thymine dimers from DNA in what was considered to be the incision step of excision repair in (Tomiyama et al., 1986). Phenethyl alcohol thus inhibited excision repair of UV-damaged DNA in (Yonei, 1980; Todo & Yonei, 1983; Tachibana & Yonei, 1985).
