Fig. 2From: Enhanced production of butyric acid through immobilization of Clostridium tyrobutyricum in a novel inner disc-shaped matrix bioreactorSchematic of the inner disc-shaped matrix bioreactor (IDSMB). The inner disc-shaped immobilization matrix consisted of a stainless steel wire mesh covered with fabric (a). Matrices (interval between each matrix 0.5 cm) were fixed in a 5-L stirred-tank bioreactor (diameter 17.5 cm) (b). c Picture of the actual inner disc-shaped matrixBack to article page
