ATP levels of three marine isolates (a Vibrio sp., Serratia marcescens , and an unidentified rodshaped organism) were measured during nutrient‐limiting conditions for free‐living bacteria or cells adhered to a glass/liquid interface. In all strains there was a higher content of ATP per biovolume (numbers × cell volume) for cells starved at the glass/liquid interface compared with those in the bulk phase. Leakage from viable cells and the formation of a conditioning film are suggested only partly to explain the elevated levels of ATP per biovolume at the surface.
