Sažetak
Solid state fermentation (SSF) is defined as fermentation process performed in the absence of free water on non-soluble materials which can act as physical support and source of nutrient to microorganisms. In this paper, Aspergillus ochraceus was cultivated in solid state fermentation using sugar industry waste. In order to decolorize dyes, two different methods were applied using sugar beet waste a) as a substrate for A. ochraceus cultivation and as dyes adsorbent ; and b) as a substrate for A. ochraceus cultivation with the aim of extracellular enzymes production that can be used for dyes decolorization in batch experiments. 100 % conversion of textile violet dye decolorization, 57 % of textile green dye decolorization, 41.1 % of congo red and 51.9 % conversion of metylene blue was reached in batch experiments using produced extracellular enzymes.
