Summary. It has been established that the hemicelluloses of various waste vegetable materials can be hydrolysed by acids to yield extracts fermentable by alcohol forming bacteria. A study has been undertaken of the conditions under which Bac. acetoethylicus Northrop can be utilised for the fermentation of the extract obtained by the hydrolysis of various vegetable materials and the conditions have been ascertained under which the fermentation may be technically applied. A method is described for carrying out this fermentation without the application, for the preparation and sterilisation of the mashes, of temperatures exceeding those of boiling water.
