绿草履虫与一种内生的小球藻Chlorella conductiva（Brandt）是共生关系。研究了草履虫对NaH_（14）CO_3的吸收，结果表明，含藻共生体的草履虫吸收NaH_（14）CO_3，而不含藻共生体的草履虫不吸收NaH_（14）CO_3。从草履虫乙醇提取物中鉴定出放射性麦芽糖、葡萄糖、果糖和苹果酸，草履虫向小球藻的物质转移和小球藻向草履虫的其他物质转移表明这是一种互惠关系，两种生物都从中受益。
Paramecium bursaria(Ehrenberg) and an endozoic zoochlorellaChlorella conductrix(Brandt) live in a symbiotic relationship. Uptake of NaH14CO3was studied to determine if carbohydrate products of photosynthesis are transferred to the host paramecium.Paramecium bursariacontaining the algal symbionts took up NaH14CO3but those without the algal symbionts did not. Radioactive maltose, glucose, fructose and malate were identified from the ethanolic extract of paramecia.Transfer of materials fromParamecium to Chlorellaand the transfer of other materials fromChlorellatoParamecium, led to the conclusion that this is a mutualistic relationship, both organisms benefiting from the relationship.
