A third organism which does not attack agar was isolated from the same source; it has been included in the present study for comparative purposes. The specific name Cytophaga salmonicolor has been given to this organism. All organisms are characterized by exhibiting flexing and gliding motility and by absence of microcysts and fruiting bodies. The organisms can be grown in a mineral glucose medium, although growth is accelerated and more abundant when a vitamin mixture is included in the medium. CO2 is an absolute requirement for growth. Growth of C. fermentans var. agarovorans and C. salmonicolor var. agarovorans on aerobic plate cultures is markedly inhibited by 0.1 % glucose or galactose. Acetic, propionic and succinic acids are major end products of sugar fermentation of all three types. C. salmonicolor and C. salmonicolor var. agarovorans form in addition CO2 and H2, and small amounts of lactic and formic acids and ethanol., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-26-2-331
