Cellulases and Xylanases Production by Penicillium echinulatum Grown on Sugar Cane Bagasse in Solid-State Fermentation.

Camassola, Marli; Dillon, Aldo J. P.

To investigate the production of cellulases and xylanases from Penicillium echinulatum 9A02S1, solid-state fermentation (SSF) was performed by using different ratios of sugar cane bagasse (SCB) and wheat bran (WB). The greatest filter paper activity obtained was 45.82 ± 1.88 U gdm in a culture containing 6SCB/4WB on the third day. The greatest β-glucosidase activities were 40.13 ± 5.10 U gdm obtained on the third day for the 0SCB/10WB culture and 29.17 ± 1.06 U gdm for the 2SCB/8WB culture. For endoglucanase, the greatest activities were 290.47 ± 43.57 and 276.84 ± 15.47 U gdm, for the culture 6SCB/4WB on the fourth and fifth days of cultivation, respectively. The greatest xylanase activities were found on the third day for the cultures 6SCB/4WB (36.38 ± 5.38 U gdm) and 4SCB/6WB (37.87 ± 2.26 U gdm). In conclusion, the results presented in this article showed that it was possible to obtain large amounts of cellulases and xylanases enzymes using low-cost substrates, such as SCB and WB.
