In terms of temperature, three groups of strains were recognized: (i) cold-preferring where temperature optima ranged between 10.1 and 18.4°C, growth rate 0.252 and 0.344 d-1, (ii) cold- and warm-tolerating with optima above 10°C and growth rate 0.162–0.341 d-1, and (iii) warm-preferring temperatures above 20°C and growth rate 0.249–0.357 d-1. Their light requirements were low. Mean values Q10 for specific growth rate ranged from 0.7 to 3.1. The lowest Ea values were observed on cold-preferring and the highest in the warm-preferring strains. One strain from each temperature group was selected for PN and RD measurements. The PN:RD ratio of the warm preferring strains was less affected by temperature similarly as Q10 and Ea.
