Notes
Evidence is given that the colourless flagellate Oxyrrhis marina is a natural source of tryptophan in the diet of the rotifer Encentrum linnhei, which inhabits coastal rockpools in western Scotland. The rotifer feeds on this flagellate in addition to the photosynthetic alga Brachiomonas submarina. This study also shows that tryptophan excreted by one alga can be taken up by another and made available to Encentrum, a process which allows the rotifer to grow on combinations of algae which, individually, are nutritionally deficient.
