Protein patterns of wild strains of A. niger. a Acid protein patterns of A. niger. Asterisk indicated up regulated acid proteins synthesized in the stationary phase of the growth. Dots indicated proteins with peroxidase activity. G Gabčíkovo; P Pezinok; N Nováky; Š Šobov; s molecular mass standards ladder. Load per lane was 1.3 μg of soluble proteins; Gel was stained with AgNO₃ [19]. b. A. niger—acid proteins with β-1,3-glucanase activity [17]. Glu activity is strongly growing from left to right. Load per lane was 5 μg of soluble proteins. c 1-D-SDS-PAGE protein patterns of selected A. niger strains. Dots designated proteins/polypeptides with strong up/down regulation of gene expression. Load per lane was 0.8 ± 0.05 μg of proteins
