“…Pigment production. The pigment was obtained from T. rubrum grown in shake cultures as described by Silva, Kesten, and Benham (1955), and Jensen, Altschuller, and Bard (1957). The growth medium (Nickerson and Chadwick, 1946) was dispensed into 250-ml Erlenmeyer flasks in volumes of 135 ml and each flask was then inoculated with 1 ml of fungal homogenate (Vicher, Lyon, and White, 1959).…”
