WebFor a large-scale operatiorL, the stirred-tank fermenter (STF) is the most widely used design in industrial fermentation. It can be employed for both aerobic or anaerobic … WebWith cell recycling, chemostat efficiency is improved. To maintain a high cell density, the cells in the outlet stream are recycled back to the fermentation vessel. Figure 5.11 represents a chemostat unit with a cell harvesting system. The separation unit is used for harvesting the cells and recycling then to the culture vessel to increase the cell …
WebNational Center for Biotechnology Information WebThe continuous stirred-tank reactor (CSTR), also known as vat-or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering.A CSTR often refers to a model used to estimate the key unit operation variables when using a …
