title: Hemin replaces serum as a growth requirement for Naegleria.
abstract: Four strains of Naegleria gruberi were grown axenically without serum. Serum was replaced by hemin or two selected hemoproteins. Aside from the utility of eliminating serum from the culture medium, the present work shows that Naegleria does not require intact protein, and establishes a specific micronutrient requirement for this amoebo-flagellate.
