专性光养藻类鞭毛虫的噬菌性可能是在无机营养限制时期获取营养的重要策略。几种海洋藻类鞭毛虫在限制磷酸盐时表现出增加细菌活性的作用。1989年，在挪威西部的Sandsfjorden的Prymnesium parvum和1988年挪威南部和西部海岸的Chrysochromulina polylepis的水华期间，发现了藻类鞭毛虫对细菌的放牧。在这些情况下，未检测到溶解的磷酸盐。藻类鞭毛虫可以吃细菌以获得磷酸盐，这可能允许这些藻类鞭毛虫在磷酸盐变得有限时发展水华。
Bacterivory in obligate phototrophic algal flagellates may be an important strategy for acquiring nutrients during periods of inorganic nutrient limitation. Several marine algal flagellates were shown to increase bactivory when phosphate was limited. Grazing on bacteria by algal flagellates was found during blooms of Prymnesium parvum in Sandsfjorden, western Norway, in 1989 and Chrysochromulina polylepis on the south and west coast of Norway in 1988. Dissolved phosphate was not detectable in these situations. Algal flagellates may graze bacteria to obtain phosphate, which may permit these algal flagellates to develop blooms when phosphate becomes limited.
