摘　　要：[目的]探讨针晶蓝纤维藻(Dactylococcopsis rhaphidioides)对5种常用抗生素的敏感性。[方法]采用分光光度法研究了青霉素、链霉素、头孢唑啉钠、硫酸庆大霉素和氯霉素5种常用抗生素对针晶蓝纤维藻生长的影响。[结果]5种抗生素对针晶蓝纤维藻生长均有不同程度的抑制作用,其中氯霉素和链霉素抑制作用较强,而头孢唑啉钠和青霉素相对较弱。[结论]针晶蓝纤维藻培养中除菌可选用青霉素或头孢唑啉钠。[Objective] The aim was to explore the sensitivity of Dactylococcopsis rhaphidioides to 5 kinds of common antibiotics. [ Method ] Effects of common antibiotics such as penicillin, streptomycin, cefazolin sodium, gentamicin sulfate, and chloramphenicol on the growth of Dactylo- coccopsis rhaphidioides were studied by spectrophotometric method. [ Result] D. rhaphidioides displayed differently sensitive to the tested antibiot- ics. Both chloramphenicol and streptomycin exhibited a relatively strong inhibition to D. rhaphidioides ,while penicillin and cefazolin sodium had a weak inhibitory effect. [ Conclusion] Penicillin and cefazolin sodium may be used as antimicrobial agent for the axenic culture of D. rhaphidioides.
