Abstract

A method is described in which a flow sorption microcalorimeter was used to measure the heat production of Vibrio alginolyticus attached to polyacrylamide beads. Starved cells were attached to the beads and placed in the column of the calorimeter. Heat production from the metabolism of glucose by the attached cells was then determined. The specific rate of heat production of cells on the surface is compared with that of cells growing in solution. The results show a lowered rate of heat production per cell by the attached bacteria.
