Variations in DNA levels for log‐phase Euglena have been shown to be directly related to the pH of the culture medium. Data are presented here for cultures grown in Cramer and Myer's medium at pH 3.0 and 6.8. DNA levels are ∼50% greater for Euglena at the higher pH value, confirming earlier reports.
