head retention improved filtration of the mash owing to the inhibition of certain flora responsible for the synthesis of polysaccharides the improvement obtained from the point of view of filtration is illustrated on the diagram in fig3 which shows the filtration kinetics determined according to the method designated 34 brassin tepral 34 thus in this diagram the time in minutes is given on the abscissa whereas the quantity of wort filtered in grams is shown along the ordinate the curve t corresponding to the control malt not subjected to any treatment is situated considerably below the curves gc1 gc2 and gc3 corresponding to malts which have been inoculated with different strains of geotrichum candidum gc1 gc2 and gc3 it has been possible to observe that the inoculation with geotrichum candidum quite particularly during the steeping stage corresponding to the malting process also had beneficial consequences for the effluents in fact the analysis of the waters discarded after steeping shows that the inoculation of geotrichum candidum leads to a diminution of the chemical oxygen demand 34 cod 34 table vii below illustrates quite particularly the results obtained following inoculation with geotrichum candidum corresponding to the strain i 1475 in proportions of about 10 7 cfu per kilogram of barley the malted barley being of the 34.
