Abstract
Prompted by multiple applications of laccases, the fungi yielding enzyme with wider geographical applicability and other novel features was explored from Jaisalmer desert (India). One of the isolates TTF6 yielded laccase exhibiting novel many-fold amplification in activity in the presence of lead (Pb) and tolerance to Na. The peroxide-free enzyme showed apparent molecular mass 40 kDa, activity from 10 to 80 °C, temperature optima at 60 °C and pH optima at 5.0. It was highly thermostable losing only 22 and 44% of its maximal activity in 24 and 48 h, respectively, with a half-life of 60 h at 60 °C. It was found resistant to studied metals including Cu and Zn and showed tolerance to many organic solvents. The enzyme was produced best in Olga medium and induced by ethanol and copper sulfate but not by guaiacol, though guaiacol could be utilized as substrate. The partially purified enzyme decolorized selected synthetic dyes at 20–40 °C, the decolorization rate, however, was not affected by Pb. The fungus was identified on the basis of morphological and ITS sequence characteristics as A. nidulans. This is the first report of a Pb-activated laccase and the sixth phenol oxidase from A. nidulans reported so far.
