Fig. (1) Screening of laccase activity in chromatography fractions recovered from an anion exchange column (DEAE-Sepharose FF) using a microplate containing dried discs impregnated with ABTS. Upper panel: row A: fractions 1 - 10; row B: fractions 11 – 20; row C: fractions 21 - 30. Lower panel: corresponding chromatography graph showing the elution profile of total proteins (―) and spectrophotometric determination of laccase activity (•) in selected fractions (row A fractions 2, 7and 10 as well as row C fractions 27 and 29 were not determined by spectrophotometry).
