A Systematic Study of Microörganisms Which Decompose the Specific Carbohydrates of the Pneumococcus

Abstract
4 types of bacteria decomposing type-specific and non-type-specific carbohydrates of pneumococci, isolated from soils and studied in detail, are considered new spp.: Bacillus palustris* (p.429), a large spore-bearing rod decomposing specific carbohydrate of pneumococcus type III; B. p. var gelaticus* (p.429), also attacking the gel properties of agar; Flavobacterium ferrugineum (p.429), a very small non-sporulating rod attacking the non-type-specific carbohydrate of a degraded type-I pneumococcus and the so-called "C" substance from typical strains; SACCHAROBACTERIUM n. gen. (Fam. Mycobacteriaceae) (p.430) for the pleomorphic bacteria decomposing specific carbohydrate of pneumococcus types I and II, with S. ovale* (p.430) for forms (young cells oval) acting on carbohydrate of pneumococcus type II, and S. acuminatum* (p.430) for pointed rods decomposing specific polysaccharide of pneumococcus type I.
