Abstract: The remazol brilliant blue reactive (RBBR) dye decolouration and mustard (Brassica campestris) straw (MuS) nutrient utilization by various white rot fungi, viz. Phanerochaete chrysosporium, Ganoderma applanatum, G. lucidum, Pleurotus ostreatus, P. sajorcaju, Polyporus arcularius, P. versicolor, P. adustus, P. sanguineus-970, P. sanguineus-154, Trametes hirsuta, Parva mentocela and Longyites strata, were studied. The visual detection of decolouration was found complementary to its quantitative estimation. P. sanguineus-970 showed the highest RBBR dye decolouration in agar as well as in broth medium (74%). The dry matter utilization of MuS was low (20-27%) by all the white rot fungi. However, they preferentially degraded lignin (18-42%) in comparison to cellulose (0-12%). The highest lignin utilization was shown by P. chrysosporium. Whereas, P. sanguineus-154 showed both higher RBBR dye decolouration (66.5%) and lignin degradation (33%) and could be used for modification of MuS as animal feed.
