چکیده
Impacts of metals to the growth and enzyme production of fungi were tested with Cd(0-10 mg kg–1), Co(0-100 mg kg–1), Cr(0-100 mg kg–1), Li(0-100 mg kg–1) or Mn(0-400 mg kg–1) containing media with ABTS [2,2’-azino-bis (3-ethylbentzthiazoline6-sulfonicacid)] as indicator of oxidative enzymes, laccase and/ or peroxidases. All ascomycetes Alternaria sp., Chaetomium sp., Epicoccum sp., Fusarium sp. and Trichoderma harzianum, and basidiomycetes Agrocybe praecox, Pleurotus pulmonarius, Phlebia radiata, Physisporinus rivulosus and Stropharia rugosoannulata, fungi grew in the presence of metals. The growth of A. praecox was tolerant to Mn, Cr and Li. The color reaction with ABTS was present in all basidiomycetes with or without metals indicating production of oxidative enzymes. Ascomycetes did not show color zone formation with Mn, Cd, Li and without metals. Alternaria sp., Chaetomium sp., Epicoccum sp. and Trichoderma harzianum formed color zone with Co and Cr indicating enzyme production.
