TL;DR: Results indicate that the aqueous extracts of Brazilian L edodes and P sajor-caju mushrooms are potential sources of antioxidant and anticancer compounds, however, further investigations are needed to exploit their valuable therapeutic uses and to elucidate their modes of action.

TL;DR: In this article, pectinases-producing filamentous fungi were isolated with the aim of using their enzymes in the clarification of apple and blueberry juices, and the experimental extract enzyme EE obtained in solid-state process with a strain identified as belonging to the species Aspergillus niger and designated LB23 was used for treating juices and compared with two commercial enzyme preparations.
Abstract: In this work, pectinases-producing filamentous fungi were isolated with the aim of using their enzymes in the clarification of apple and blueberry juices. The experimental extract enzyme EE obtained in solid-state process with a strain identified as belonging to the species Aspergillus niger and designated LB23 was used for treating juices and compared with two commercial enzyme preparations: Pectinex ® Clear (PC) for apple juice, and Pectinex ® BE Color (PB) for blueberry juice. After the enzymatic treatment, the treated juices were evaluated with respect to parameters such as viscosity, turbidity, and degree of clarification, as well as antioxidant capacity, and total phenolic compound content. Considering all comparison criteria, the experimental preparation EE showed results statistically similar or superior to those obtained with the commercial enzyme preparations.

TL;DR: In this article, the S1M29 mutant strain of Penicillium echinulatum was used to produce enzymes with different concentrations of cellulose (20, 40, and 60g −1 ) in batch and fed-batch processes.

TL;DR: The fed-batch process was favorable for obtaining xylanases, but not for FPA and endoglucanases, suggesting that in the case of cellulases, the inducer must be added early in the process.
