Mutasi Trichoderma sp. untuk Meningkatkan Sekresi Selulase
This research is aimed to increase cellulase secretion on Trichoderma sp. by mutation method. Trichoderma PK1J2 (5x10(8) spore/ml) was turned into a suspension in utagen solution (400ug/ml ethidium bromide and 0,5 M ethyl methane sulfonate) for 120 minutes. The sreening of mutants which were able to...
