| Method |
Using high-precision microcalorimetry in a differential scanning
mode, researchers measured direct heat production at a constant temperature,
against a background signal of culture medium, from
five phyla (three kingdoms) of eukaryotic protists spanning more
than 5 orders of magnitude in carbon biomass, and representing
a large range of cell densities, sizes, and total cell carbon (Table
1). |
| Comments |
When heat production is normalized to biomass (pW/pgC), a
nearly constant heat production is obtained for all cells
(Kruskal-Wallis test, P=0.09), with a median of 0.037 pW/pgC and a 95% confidence interval (CI) of 0.022–0.061 pW/pgC. |
