ABSTRACT:
A new process for cultivating selected cultures involves initially removing broth at a first rate from a fermentation and replacing it with supporting medium, the replacement rate thereafter being increased to remove cultures of lower growth rate than the selected culture. A new process for the microbiological synthesis of protein-containing material by an aerobic fermentation in a supporting medium uses a normally gaseous hydrocarbon substrate selected from nethane, ethane, propane and butane and a protein-producing fungus of graphium species. It has not been known hitherto for such syntheses to be possible with a fungus. The said substrate may be natural gas.
