Physiology of phototrophic iron(II)-oxidizing bacteria: implications for modern and ancient environments.

abstract：:The effect of a brief (24 h) temperature shift to 4 degrees C (low-temperature stress) or 50 degrees C (high-temperature stress) was studied in methanogenic slurries of Italian rice field soil incubated at either constant 30 degrees C or 15 degrees C. Low-temperature (low-T) stress showed no effect in either the 30 de...
