  • Title: [Selection of Trichoderma viride, a producer of cellulase].
    Author: Ostrikova NA, Konovalov SA.
    Journal: Mikrobiologiia; 1980; 49(4):540-5. PubMed ID: 7191044.
    Abstract:
    A mutant strain of Trichoderma viride producing cellulase has been obtained as a result of three-stage selection using chemical and physical factors. New variants with modified characteristics appeared after the action of nitroso compounds on a suspension of conidia at the first stage of selection and the action of temperature at the second stage. The new characteristics were intensified and became stable at the third stage of selection. The experimental mutagenesis yielded an active an active mutant of Trichoderma viride 44 which synthesized cellulase (up to 22 units/ml) four times better than the parent culture Trichoderma viride F-57.
