Pleurotus djamor is an edible mushroom that produces proteases. However, the production of these enzymes needs to be optimized and applied in experimental models. This study aimed to optimize the production of proteases by Pleurotus djamor using agricultural waste and to evaluate the anthelmintic activity of proteases in vitro. Solid-state fermentation optimized protease production, with wheat bran as the substrate. For this, the central composite design (CCD) was used. The proteolytic activity was determined after the preparation of the cell-free crude extract. In addition, eggs of the helminths Taenia solium and Moniezia sp. were used to evaluate the in vitro anthelmintic activity of the proteases. The results showed that moisture significantly influenced (p < 0.01) protease production. On the other hand, within the evaluated intervals, the incubation time was non-significant (p > 0.05). The enzymes led to a significant reduction (p < 0.01) in T. solium and Moniezia sp. eggs, with reductions of 33.44% and 45.43%, respectively, compared to the control with denatured enzymes. The results suggest the action of proteases in the degradation of helminth eggs, demonstrating their potential for biochemistry control.
红平菇是一种能产生蛋白酶的可食用蘑菇。然而,这些酶的产量需要优化并应用于实验模型。本研究旨在利用农业废弃物优化红平菇蛋白酶的产量,并评估蛋白酶在体外的驱虫活性。以麦麸为底物,通过固态发酵优化蛋白酶的生产。为此,采用了中心复合设计(CCD)。制备无细胞粗提物后测定蛋白水解活性。此外,还使用了猪带绦虫和莫尼茨绦虫的虫卵来评估蛋白酶的体外驱虫活性。结果表明,水分对蛋白酶产量有显著影响(p < 0.01)。另一方面,在所评估的时间间隔内,孵育时间无显著影响(p > 0.05)。与变性酶对照组相比,这些酶使猪带绦虫和莫尼茨绦虫虫卵数量显著减少(p < 0.01),分别减少了33.44%和45.43%。结果表明蛋白酶在降解蠕虫卵方面有作用,证明了它们在生物化学防治方面的潜力。
