Influence of temperature on growth rate and competition between two psychrotolerant antarctic bacteria: low temperature diminishes affinity for substrate uptake.

Type of article: Article

Summary

The growth kinetics of two psychrotolerant Antarctic bacteria, Hydrogenophaga pseudoflava CR3/2/10 and Brevibacterium sp. strain CR3/1/15, were examined over a range of temperatures in both batch culture and glycerol-limited chemostat cultures. The results explain recent reports of decreased affinity for substrates by heterotrophic bacteria in polar seas, with consequently increased difficulty of substrate uptake at low temperature, and may also be significant in explaining the limitation of primary production in the Southern Ocean.
