Abstract:
:Mycelial culture of Pleurotus florida produced highest extracellular laccase in optimum growth medium. At least two laccases (L(inf1) and L(inf2)) were shown to be present in the culture filtrate. Low-laccase-yielding mutants with impaired L(inf2) 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.
