Resumo: 	Minimidochium parvum LPSC # 548, a fungus isolated from litter floating on waters of Río Santiago (Provincia de Buenos Aires, Argentina) polluted with industrial effluents and crude-oil, was grown as a shaking culture on a C-limited medium to evaluate its ability to produce extracellular laccase. The effect of anthracene, CuSO4 · 5H2O, ethanol, guaiacol, humic acids, Kraft lignin, MnSO4· H2O, Tween 20 and veratryl alcohol on its growth and extracellular laccase activity levels was also analyzed. The cultures grown on basal medium produced maximum biomass (over 420 mg/100 ml) and maximum extracellular laccase activity (351.7 ±53.3 pkat/ml) after 5 days of incubation. Among the different factors tested, only the humic acids at 0.1 % (w/v) were found to stimulate the growth of M. parvum . However, Tween 20 (0.1 %, v/v) was the only one that produced an increase of laccase activity levels up to 2.5-fold compared to the control.
