Abstract

This study led in the pioneering technique incubated in a bioreactor with the forced air injection system. The purpose of this study was to establish the optimal incubation conditions for this technique. The results showed that the speed at which Inonotus obliquus was incubated with the forced air injection system was superior to that with a normal bioreactor. A nitrogen to oxygen ratio of 50:50 provided the best results with the forced air injection system, including in terms of the achievement of biomass, total triterpenes, betulinic acid content, and the scavenging activities of DPPH radicals, which reached up to 21.3 g/1000 mL, 2.1 g/1000 mL, 1.9 g/1000 mL, and 87.3%, respectively. The results showed that the bioreactor with the forced air injection system could more effectively incubate I. obliquus by using less vapor while still utilizing a model close to that of a traditional bioreactor. The innovative bioreactor fermentation model was thus more economical than the traditional bioreactor model.

斜切inonotus的深层发酵与控制气氛处理对提高生物活性成分含量的影响。

摘要

这项研究引领了采用强制空气喷射系统在生物反应器中培养的开创性技术。这项研究的目的是为该技术建立最佳的孵育条件。结果表明，用强制空气注射系统孵育斜肌inonotus的速度要优于使用普通生物反应器的速度。氮气与氧气的比例为50:50时，强制空气喷射系统提供了最佳结果，包括获得的生物量，总三萜烯，桦木酸含量和DPPH自由基的清除活性，达到21.3 g / 1000 mL，2.1 g / 1000 mL，1.9 g / 1000 mL和87.3％。结果表明，带有强制空气喷射系统的生物反应器可以更有效地孵育通过使用较少的蒸气而仍使用与传统生物反应器相似的模型的斜肌。因此，创新的生物反应器发酵模型比传统的生物反应器模型更经济。
