食菌原生动物发生在大多数土壤中，但其数量的重要性的数据是稀疏的，可能是由于缺乏合适的计数技术。我描述了一个修改的最可能的数方法计数的食菌原生动物，特别是鞭毛虫，土著土壤真菌和酵母菌作为他们的食物来源，在大的个人威尔斯在24孔微量滴定板。约10（3）真菌鞭毛虫g（-1）干土壤中存在于所有土壤检查。在向土壤中添加葡萄糖后一周内，食菌鞭毛虫的反应增加了4倍。它们的丰富性和对环境变化的快速反应表明，在决定土壤中酵母细胞和真菌分生孢子的数量方面，真菌鞭毛虫发挥着重要作用。(C)1998爱思唯尔科技有限公司版权所有。
Mycophagous protozoa occur in most soils, but data on their quantitative importance are sparse, possibly due to a lack of suitable counting techniques. I describe a modification of the most probable number method for enumeration of mycophagous protozoa, especially flagellates, with indigenous soil fungi and yeasts as their food source in large individual wells in 24-well microtitre plates. About 10(3) mycophagous flagellates g(-1) dry soil were present in all soils examined. Mycophagous flagellates responded by a 4-fold increase in a week after addition of glucose to soil. Their abundance and quick response to environmental changes suggest an important role for mycophagous flagellates in determining the size of populations of yeast cells and fungal conidia in soil.
