固态发酵技术研究分析及应用

Research analysis and application of solid-state fermentation technology

固态发酵(Solid-state Fermentation,SSF)有着悠久的历史,它是在水存在较少的情况下进行的一种微生物发酵。目前固态发酵已经在饲料、酿酒、医药等领域有了十分重要的地位,但是对于固态发酵的研究和优化还在不断继续。相比于深层液体发酵,固态发酵对于常规影响因素:温度、湿度、溶氧和pH的调控较为复杂和不易操控,这主要归因于其基质难以在反应器中均匀存在所致。本文阐述了固态发酵及其相关影响因素并介绍了相关应用领域的特色专业设备,以期对新型固态发酵设备的研发及工艺开发提供相关依据。

Solid-state fermentation(SSF)has a long history.It is a kind of microbial fermentation in the presence of less water.So far,SSF has played an important role in feed,wine-making,medicine and other fields,but the research and optimization of solid-state fermentation continue.Compared with the deep liquid fermentation,the regulation of solid-state fermentation of conventional factors such as temperature,humidity,DO and pH is more complex and difficult to control,mainly due to the fact that the matrix is difficult to exist uniformly in the reactor.In this article,the solid-state fermentation and its related influencing factors was described and the special professional equipments in related application fields were introduced,in order to provide relevant basis for the research and development of new solid-state fermentation equipment and process development.
