IMPORTANCE OF LACCASE IN VEGETATIVE GROWTH OF PLEUROTUS-FLORIDA

Mycelial culture of Pleurotus florida produced highest extracellular l accase in optimum growth medium. At least two laccases (L-1 and L-2) w ere shown to be present in the culture filtrate. Low-laccase-yielding mutants with impaired L-2 activity had poor mycelial growth and could not form fruit body, whereas the revertants from the same mutants were similar to the parent in mycelial growth and fruit body formation.
