Thermomyces lanuginosus strains from different culture collections, namely ATCC 26909, ATCC 22083... more Thermomyces lanuginosus strains from different culture collections, namely ATCC 26909, ATCC 22083, DEN 1457, IMI 84400 and BS1 were compared for xylanase production, and isozyme profile. Of all the strains of T. lanuginosus, BS1 a soil isolate produced the largest amount of xylanase. All strains were found to produce two forms of xylanase (I & II) with molecular mass corresponding to 25.0 and 54.0 KDa. The u.v/NTG mutagenesis of T. lanuginosus BS1 aleurospores/protoplasts resulted in xylanase-hyperproducing mutants. A morphological colour mutant RB 524 produced approximately 2.5-fold higher xylanase (2506.0 units/ml) as compared to the parent strain (1018.1 units/ml).
