SUMMARY All test cultures of Pseudomonas fluorescens established growth in a basal medium (0.02% Mg SO 4 , 0.1% KH 2 PO 4 , and 0.5% glucose) with NH 4 H 2 PO 4 , NaNH 4 HPO 4 , or (NH 4 ) 2 HPO 4 as the sole source of nitrogen. NH 4 Cl 2 NH 4 NO 3 , and (NH 4 ) 2 SO 4 supported growth of the majority of the cultures. Complex organic N substrates were readily utilized by all test cultures. Glutamic acid, leucine, and proline were satisfactory sources of both nitrogen and carbon for all test cultures. With NH 4 H 2 PO 4 as the sole source of nitrogen, fructose, galactose, glucose, mannose, maltose, trehalose, starch, arabitol, erythritol, glycerol, inositol, scyllo inosose, citric acid, malie, pyruvic, caprylic or capric acid supported growth of all cultures. 1‐Nonanol, 1‐decanol, and 1‐hendecanol were satisfactory carbon sources.
