title: Prototheca zopfii Krüger Strain UMK-13 Growth on Acetate or n-Alkanes.
abstract: A new strain of Prototheca zopfii Krüger was grown on acetate or on pure n-alkanes. A maximum acetate-supported exponential growth of 12 divisions day occurred at pH 5 and 30 degrees C. At 25 degrees C, growth on n-alkanes was almost as fast, but no growth occurred at 30 degrees C. After 4 days at 25 degrees C, 34 to 45% of the n-alkanes had been removed, whereas at 21 degrees C and slower growth, utilization was twofold greater after 15 days. Rates of growth and utilization increased markedly after a point of sudden emulsification.
