Cellulase hyperproducers constructed from polyploids of Lentinus edodes.
A mycelial mat of Lentinus edodes was treated with 0.01% (w/v) colchicine solution for 240 h at 26 degrees C and autopolyploidization occurred. The mycelia were treated subsequently with the haploidizing reagent, benomyl, and fanshaped sectors were produced from colonies. Among such sectors, cellulase hyperproducers could be selected. The cellulase productivity of the hyperproducer, L1, did not decrease through five generations.
