摘要

微生物菊粉酶在生物技术领域有许多应用。本研究研究了作为菊粉酶生产者的韦氏曲霉（Aspergillus welwitschiae）的新菌株，并对其内在和外在菊粉酶进行了硅学表征和蛋白质建模。采用 Dohelert 法评估温度和培养湿度之间的相互作用，发现韦氏酵母菌生产的菊粉酶活性提高了四倍。最佳温度和湿度分别为 25-27 °C 和 75-82%。该酶在 pH 值为 3.5 和 60 °C 时表现出最佳活性。水解剑麻根可产生 272 毫克/克的还原糖和低聚糖。我们在硅学实验中预测了 10 个来自 A. welwitschiae 的内源性（5 个）和外源性（5 个）菊糖酶的有效结构。这些菊粉酶对菊粉的显著活性凸显了它们在处理农用工业残留物以生产高附加值产品方面的潜力。

Production and application of inulinase by new isolates of Aspergillus welwitschiae from fermented peach-palm waste for the production of fructooligosaccharides

Microbial inulinase enzymes have a number of applications in biotechnology. In this study, new strains of Aspergillus welwitschiae were investigated as producers of inulinases and their endo- and exo-inulases were characterized in silico and their protein modeling was performed. The inulinase production by A. welwitschiae employing the Dohelert method to assess the interaction between temperature and cultivation humidity, resulted in a fourfold increase in activity. The optimal temperature and humidity were 25–27 °C and 75–82 %, respectively. The enzyme exhibited optimal activity at a pH of 3.5 and at 60 °C. The hydrolysis of the sisal root yielded 272 mg/g of reducing sugars and oligosaccharides. Our in silico experiments predicted 10 well-validated structures of endo- (5) and exo-inulinases (5) from A. welwitschiae. The notable activity of these inulinases on inulin highlights their potential for the treatment of agro-industrial residues with the objective of producing high-value added products.
