叶绿酸酯的光敏杀菌作用

Lethal Photosensitization of Chlorophyllin Ester

摘要:

广泛使用抗生素治疗细菌感染是导致抗生素抗性菌增加的重要原因,研究杀菌的其他方法,如光敏杀菌法等十分必要.研究结果表明,叶绿素的降解产物叶绿酸酯对白葡萄球菌(Staphy lococcusalbus)有显著的光动力杀伤作用,而对大肠杆菌(Escherichiacoli)的生长没有影响;葡萄球菌较大肠杆菌能更有效地吸附叶绿酸酯,导致对生长的抑制.

Abstract:

The extensive use of antibiotics has resulted in an increase of antibiotic resistant strains of bacteria. Alternative methods such as photodynamic therapy are necessary for the inhibition of bacteria. In the present study, the chlorophyllin ester was foun
