SUMMARYMarine bacteria from Atlantic coastal waters off Florida, isolated by a technique assuring that all would grow on a sea-water medium but not on a distilled water medium, were studied; 96 of 100 original isolates were characterized by morphological and some physiological properties, particularly those related to mineral responses. All isolates were Gram-negative rods or spiral forms, grew well in a simple saline-peptone medium, and most were pigmented and motile. All isolates required NaCl for good growth, and groupings could be clearly established for those whose mineral nutrition was satisfied, in a casein digest broth, by adding NaCl only, NaClfKCl, NaCl+Mg salts, or all three salts. Lytic susceptibility in various mineral solutions and growth tolerance to various salt levels were studied. Some overall similarities, and a few correlations between mineral nutrition and physiological versatility, were established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
