An investigation was undertaken to study the marine members of the order Myxobacteriales. Samples of mud, sea water, sediments, cores, and plankton tows were plated on a variety of media. Myxobacteria were isolated from most of the samples. Eight types were chosen for study on the basis of general properties which included colonial characteristics and pigmentation, microscopic cellular differences, action on agar, and the presence or absence of microcysts. Characterization of the 8 isolates was based on studies involving cytological and morphological investigations, biochemical and physiological differentiation, nutritive requirements, and enzymatic activity. The investigation showed that 1 all the isolates had typical myxobacterial characteristics 2 all were aerobic and none used cellulose 3 a wide range of nutritional requirements existed among the different species and 4 a typical glycolytic scheme was present in 3 of the isolates. On the basis of these different characters, 5 different species were recognized.
