Various fungal species can degrade lignocellulolytic materials with their enzyme cocktails composed of cellulolytic and lignolytic enzymes. In this work, seven fungal species ( Mucor indicus  DSM 2185,  Paecilomyces variotii  CBS 372.70,  Myceliophthora thermophila  CBS 663.74,  Thielavia terrestris  CBS 456.75,  Botryosphaeria dothidea  JCM 2738,  Fusarium oxysporum  f.sp.  langenariae  JCM 9293, and  Fusarium verticillioides  JCM 23107) and four nutrient media were used in the screening for effective lignocellulose degrading enzymes. From the seven tested fungi,  F. oxysporum  and  F. verticilliodes , along with nutrient medium 4, were selected as the best medium and producers of lignocellulolytic enzymes based on the determined xylanase (>4 U mg −1 ) and glucanase activity (≈2 U mg −1 ). Nutrient medium 4 supplemented with pretreated corn cobs was used in the production of lignocellulolytic enzymes by sequential solid-state and submerged cultivation of  F. oxysporum ,  F. verticilliodes , and a mixed culture of both strains.  F. oxysporum  showed 6 times higher exoglucanase activity (3.33 U mg −1 ) after 5 days of cultivation in comparison with  F. verticillioides  (0.55 U mg −1 ).  F. oxysporum  also showed 2 times more endoglucanase activity (0.33 U mg −1 ). The mixed culture cultivation showed similar endo- and exoglucanase activities compared to  F. oxysporum  (0.35 U mg −1 ; 7.84 U mg −1 ). Maximum xylanase activity was achieved after 7 days of cultivation of  F. verticilliodes  (≈16 U mg −1 ), while  F. oxysporum  showed maximum activity after 9 days that was around 2 times lower compared to that of  F. verticilliodes.  The mixed culture achieved maximum xylanase activity after only 4 days, but the specific activity was similar to activities observed for  F. oxysporum.  It can be concluded that both fungal strains can be used as producers of enzyme cocktails for the degradation of lignocellulose containing raw materials, and that corn cobs can be used as an inducer for enzyme production.
