Abstract

Growth characteristics of a facultatively halophilic strain of Micrococcus, capable of growth in medium containing no added NaCl and in medium containing 5.5 M NaCl, were studied over a range of salt concentrations and temperatures. Optimal growth occurred at 35C in a medium containing 1.0 M NaCl. In a medium containing 0.1 M NaCl, growth only occurred if the incubation temperature was less than 30C. No growth occurred if KCl, LiCl, NH4Cl, MgCl2, or sucrose was substituted for NaCl at 35C. A reexamination of bacteria previously described as moderate halophiles is suggested.

摘要

研究了一种兼性嗜盐微球菌菌株的生长特性，该菌株能够在不添加氯化钠的培养基以及含有5.5 M氯化钠的培养基中生长，研究范围涵盖了一系列盐浓度和温度条件。在含有1.0 M氯化钠的培养基中，35℃时生长最佳。在含有0.1 M氯化钠的培养基中，只有当培养温度低于30℃时才会生长。在35℃时，用氯化钾、氯化锂、氯化铵、氯化镁或蔗糖替代氯化钠时均不生长。建议重新审视先前被描述为中度嗜盐菌的细菌。
