“…, Bacterium (Tausz and Peter, 1919;Tausz and Donath, 1930;Grey and Thornton, 1928), Pseudomonas (S6hngen, 1913;Grey and Thornton, 1928;Lee and Chandler, 1941;Haas, Yantzi, and Bushnell, 1941;Bushnell and Haas, 1941), Bacillus (Tausz and Peter, 1919; Grey and Thornton, 1928), and possibly others,-Bacterium aliphaticum, described by Tausz and Peter (1919), is outstanding. This organism, whose respiration and growth with hydrocarbon substrates has been more recently studied by Johnson, Goodale and Turkevich (1942), is apparently unable to metabolize aromatic hydrocarbons but will develop in simple inorganic media containing any one of numerous, highly purified aliphatic compounds, from pentane to paraffin oil.…”
