^aCon, control medium, YEPD (pH 3.0). Acid-supplemented media were control medium supplemented with 1, 5, or 30 mM of the indicated acid, adjusted to pH 3.0. Oxa, oxalic acid; Ace, acetic acid; Mal, malonic acid; Pro, propionic acid; For, formic acid; +, confluent growth on YEPD agar for both the undiluted and diluted aliquots of cells exposed for 3 days as described in Materials and Methods; ±, weak growth; −, complete absence of growth.
