Growth and cellulase activities of Del scaff15, Del 72076 and their parental strains. Growth medium TrMM 4% lactose 2% spent grain extract 0.05% peptone pH 4.8. Growth was monitored by measuring the mycelium dry mass (A. Del scaff15 and D. Del 72076) and pH (B. Del scaff15 and E. Del 72076). Cellulase activities of two major cellulases CBHI and EGI was assayed using MUL substrate (C. Del scaff15 and F. Del 72076).
