Research ArticleOpen accessIn the abstractMaximizing Fungal Growth in State-of-the-Art Tray Solid-State Fermenter: Aeration Strategies Optimized for Enhanced PerformanceMusaalbakri Abdul Manan, Colin WebbThis study introduced a tray fermenter, featuring eight layers of squared perforated trays, specifically designed for solid-state fermentation applications. It is named the multi-layer squared tray solid-state fermenter. The fermenter employs two aeration strategies with varying air flow rates to optimize fungal growth. Firstly, sterilized moistened air at 8 L/min flows from the bottom through the perforated trays. Secondly, a … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 9 Apr 2024 · 6,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Chelating Process of Polysaccharides of Lyophyllum decastes with Zinc and Its Antioxidant ActivityBing Xu, Yi Dai, Jing Hong, Yiyong ChenIn this study, polysaccharides of Lyophyllum decastes (LDS) were used as raw material. The chelating rate was set as the index, the effect of chelating time, mass ratio and initial mass concentration on chelating rate was investigated. Response surface method was used to optimize the preparation technology of LDS and Zinc (Ⅱ) chelate (LDS-Zn) based on single factor experiments. LDS-Zn … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 26 Aug 2020 · 11,761 accessesView PDFCite
