Bloodsfalls Microbial Activity Summary: Bacteria at the source of Blood Falls incorporated thymidine into TCA-insoluble products at an average rate of 1.5 x 10-3 nM d-1. There was considerable variation between the samples, with rates ranging from 0.4 to 3.0 x 10-3 nM d-1 (SD = 1.1 x 10-3). Thymidine incorporation experiments were used to compute cell doubling times ranging from 37 to 54 days at 0 °C. The effect of temperature on leucine incorporation was determined at 0 °C, 5 °C, 10 °C, 15 °C, 20 °C and 30 °C . The activation energy (Ea) over the range of temperatures tested, and the Q10 for metabolic activity between 0 and 20 °C were 8764 kcal mol-1 and 1.74, respectively.
