嗜麦芽寡养单胞菌降解羽毛5L发酵罐工业小试过程研究
Study on Stenotrophomonas maltophilia DHHJ fermentation in5 L fermenter pilot plant
摘要
Abstract
In order to industrialize the utilization of waste feather by microbiological method,the scale-upof fermentation from shaking flask to 5 L fermenter for Stenotrophomonas maltophilia DHHJ based on the study of fermentation in erlenmeyer flask was investigated.Further,this paper analyzed the fermentation process and optimized the technological parameters.The changes of material and energy in metabolic processes were conjectured,and the product formation of DHHJ batch fermentation kinetics was studied.Finally,under the circumstances of O.08 MPa pressure,2.5 L/min air flow.defined temperature of 40 ℃ and other controlled conditions,this yield was 1～2 fold higher in comparison with the shaking flask fermentation,fermentation period shortened by one day.And it provided the reliable basis for the use of the feather waste.关键词
