“…In the latter communication they reported marked stimulation of bacterial growth by small amounts of extracts of yeast cells, and of certain vegetables such as green peas, string beans and tomatoes. Wagner, Dozier and Meyer (1924) emphasized the high "biologic value" of mediums contain-EDWARD W. MORRISON AN] LEO F. RETTGER ing beef heart infusion, and the superiority of these mediums over others in the original isolation of the anaerobic bacteria from spores.…”

“…Sears (1916), Waksman (1917), DeBord (1923) and Kendall, Day and Walker (1913) used both ammonia and amino-acid nitrogen determinations as methods for following protein decomposition. Kendall (1922), Kendall, Haner and Bly (1922) and Wagner, Dozier and Meyer (1924), used intermediate protein degradation products as well as ammonia and amrino nitrogen as criteria of proteolysis.…”

The Proteolytic Action of Certain Lactic Acid Bacteria

Although the action of the lactic acid bacteria on carbohydrates has been the subject of many investigations, comparatively little attention has been paid to their proteolytic activity. Kulp and Rettger (1924) found that from 2 to 6 per cent of the proteins i milk were broken down by L. acidophilus and L. bulgaricus.Oila-Jensen (1919) studied the proteolytic action of a large number of lactic acid bacteria on the proteins of milk and Witte's peptone broth. In milk from 0 to 22.7 per cent of the total nitrogen was changed into soluble forms and in Witte's peptone the amino nitrogen produced varied from 0.5 to 33.9 per cent of the total. Ammonia nitrogen generally amounted to less than 2 per cent of the total nitrogen. Itano (1916) in studying the influence of hydrogen ion concentration upon the proteolytic activity of S. lacticus obtained an increase of 8.7 to 33.5 per cent in the amount of amino nitrogen. Sears (1916) reported that B. acidi-lactici produced much more ammomna and amino nitrogen when glucose was left out of the medium than when it was included.Various criteria have been used by different investigators as indexes of proteolysis. The early investigators, Smith (1897) and Peckham (1897), took putrefactive products as a test, Heller (1921) employed pH changes, Hall (1922) used liquefaction of coagulated proteins and gelatin as standards, Kendall and Walker 1 This work was supported in part by a grant from the special research fund of the University of Wisconsin. The authors are indebted to Miss Katherine M. Bolliger for assistance in the analytical work.

“…Several investigators have quantitatively measured organic acids produced during the protein metabolism of the anaerobes, but no systematic study of the significance of these acids has been reported. Wagner, Dozier, and Meyer (1924) state that in a general way volatile acid production parallels ammonia accumulation for C. botulinum, C. tetani and C. sporogenes, and these same investigators (1925) draw "derived curves" showing among other things the relationship of these products to each other. In so far as the writers are aware, no one has ever shown any quantitative relationship to exist between ammonia and volatile acid production by the putrefactive anaerobes.…”
