Fig. 73.—Showing the characteristic stellate cells of the pith of same reed used as filtering material in clarifying sak^. Bundles of the pith are placed in the bottom of a perforated cask, forming a layer a foot or more in depth; through this the sak^ percolates. The impurities are caught in the intercellular spaces of the pith. vessel masticating the roots which are then expectorated into the vessel. The ferment ptyalin of the saliva converts the starch into saccharine sub- stances which is then acted upon by the Saccharomyces, resulting in an alcoholic drink which is said to have a very peculiar flavor. Pressed yeast cakes for bread making are prepared as follows: The filtered saccharine yeast mash in vats, is inoculated with pure cultures of Saccharomyces cerevisem. Active fermentation takes place in the.
