Studies on the Marine Bacteria II : On the Specificity of Mineral Requirements of Marine Bacteria
This study was undertaken to test the requirement of marine bacteria for inorganic salts, with an attempt to establish a reliable criterion to distinguish true marine bacteria from terrestrial ones. In this paper the author deals with the results of morphological and physiological tests, with specia...
