The aim of this study was to investigate the effect of atmospheric pressure cold plasma on the microbial substrate utilization and biomass yield in a thermophilic strain. Geobacillus sp. strain WSUCF1, a thermophile capable of producing cellulolytic enzymes with higher activity was used for this investigation. Treatment with cold plasma for 4 min increased the rates of glucose utilization by 74% and biomass yield by 60% when compared with the control. WSUCF1 treated with plasma also displayed enhanced biofilm formation. This study for the first time, reports the use of cold plasma for enhancing the substrate utilization and biofilm formation in a thermophile.
本研究旨在探究大气压冷等离子体对嗜热菌株微生物基质利用和生物量产量的影响。使用具有更高活性纤维素酶生产能力的嗜热菌 Geobacillus sp. 菌株 WSUCF1 进行了此项研究。与对照组相比，冷等离子体处理 4 分钟可将葡萄糖利用率提高 74%，生物量产量提高 60%。经等离子体处理的 WSUCF1 还表现出增强的生物膜形成。本研究首次报道了大气压冷等离子体在增强嗜热菌基质利用和生物膜形成方面的应用。
