Abstract: The remazol brilliant blue reactive (RBBR) dye decolouration and mustard (<i style="">Brassica campestris</i>) straw (MuS) nutrient utilization by various white rot fungi, viz. <i style="">Phanerochaete chrysosporium, Ganoderma applanatum,</i> <i style="">G. lucidum</i>, <i style="">Pleurotus ostreatus</i>, <i style="">P. sajorcaju</i>, <i style="">Polyporus arcularius</i>, <i style="">P. versicolor</i>, <i style="">P. adustus</i>, <i style="">P. sanguineus</i>-970, <i style="">P. sanguineus</i>-154, <i style="">Trametes hirsuta</i>, <i style="">Parva mentocela </i>and <i style="">Longyites strata</i>, were studied. The visual detection of decolouration was found complementary to its quantitative estimation. <i style="">P. sanguineus</i>-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 <i style="">P. chrysosporium</i>.<i style=""> </i>Whereas<i style="">, P. sanguineus</i>-154 showed both higher RBBR dye decolouration (66.5%) and lignin degradation (33%) and could be used for modification of MuS as animal feed.
