He developed a nutritional assay method for vitamin B12 using Euglena that was used for many years in hospitals to test for B12 levels in blood, eventually being replaced by other methods

Since " Euglena " have features of both animals and plants, early taxonomists, working within the Linnaean three-kingdom system of biological classification, found them difficult to classify.
23.
In " Euglena ", one flagellum is very short, and does not protrude from the cell, while the other is relatively long, and often easily visible with light microscopy.

Among the green euglenoids themselves, Pringsheim recognized the close kinship of some species of " Phacus " and " Lepocinclis " with some species of " Euglena ".
25.
In 2015, Dr Ellis O'Neill and Professor Rob Field have sequenced the transcriptome of " Euglena gracilis ", which provides information about all of the genes that the organism is actively using.
26.
Montandon, P . and Stutz, E . ( 1984 ) and Hallick, R . B . et al . ( 1988 and 1989 ) reported examples of a novel type of introns in Euglena chloroplast.
27.
As the cell rotates with respect to the light source, the eyespot partially blocks the source, permitting the " Euglena " to find the light and move toward it ( a process known as phototaxis ).
28.
In 1997, a morphological and molecular study of the Euglenozoa put " Euglena gracilis " in close kinship with the species " Khawkinea quartana ", with " Peranema trichophorum " basal to both.
29.
Two years later, a molecular analysis showed that " E . gracilis " was, in fact, more closely related to " Astasia longa " than to certain other species recognized as " Euglena ".
