Isolation, culture and characterization of a new strain of Euglena gracilis

A new strain of Euglena gracilis Klebs has been isolated from a highly polluted river; it was named MAT. Strain growth in different culture media was evaluated under heterotrophic and autotrophic conditions. Total lipid, sugar, protein and chlorophyll a production were studied. Results obtained for...
