Embrapa Agroenergia has been conducting genetic improvement of filamentous fungi to increase the production of cellulases and hemicellulases to deconstruct lignocellulosic biomass. In a conventional breeding program for Aspergillus niger 3T5B8 performed in 2015, after two rounds of mutagenesis (ultraviolet followed by ethyl methanesulfonate), the pectinolytic mutant strain 3T5B8-C88-P83 was selected, which presents genetic changes in the catabolite repression by glucose pathway and a significant increase in polygalacturonase production compared to the original 3T5B8 strain. This work aimed to evaluate the production of cellulolytic and hemicellulolytic enzymes of the 3T5B8-C88-83 mutant under different cultivation conditions, seeking its future application in the enzymatic processing of cotton fabrics. Endoglucanase production by the 3T5B8-C88-P83 mutant strain was evaluated in 250 mL Erlenmeyer flasks containing different liquid and solid culture media (four repetitions). |

In Brazil, despite the lack of accurate statistics on the contribution of each type of system in total milk production, it is known that pastures represent the main feed source in most production systems (IBGE, 2010). However, a major concern with respect to this factor is related to the potential environmental impact the degradation of thousands of hectares of these pastures may have. |
