研究了无机氮源对嗜酸性底栖原生动物可变裸藻种群增长的影响。硝酸钠、氯化铵和硫酸铵作为氮源进行了试验。E.在最佳盐培养基浓度下，在含有氯化铵和硫酸铵的培养基中培养的mutabilisat平衡密度比在含有硝酸钠的培养基中培养的mutabilisat平衡密度高9-11倍。E.含有硫酸铵的可变菌素培养基是快速的，并且在约10分钟后达到平衡密度的一半。228小时，这是约。比在含氯化铵培养基中提前77 h。以硫酸铵为氮源的培养基中，最大菌群密度最高，生长速度最快。
The effect of inorganic nitrogen source on population growth ofEuglena mutabilis, an acidophillic benthic protozoa colonizing on the sediment of acid mine drainage, was investigated. Sodium nitrate, ammonium chloride, and ammonium sulfate were tested as nitrogen sources. The population density ofE. mutabilisat equilibrium density cultivated in ammonium chloride‐ and ammonium sulfate‐containing media was 9–11 times higher than that in sodium nitrate‐containing medium at the optimal salt medium concentration. The population growth ofE. mutabilisin ammonium sulfate‐containing medium was rapid and reached half of the equilibrium density after ca. 228 h, which was ca. 77 h earlier than that in ammonium chloride‐containing medium. Culture medium with ammonium sulfate as the nitrogen source achieved the highest maximum population density and the fastest growth rate among the three nitrogen salts used as nitrogen sources.
