G. Zellner et H. Kneifel, CALDOPENTAMINE AND CALDOHEXAMINE IN CELLS OF THERMOTOGA SPECIES, A POSSIBLE ADAPTATION TO THE GROWTH AT HIGH-TEMPERATURES, Archives of microbiology, 159(5), 1993, pp. 472-476
Cells of the extremely thermophilic, strictly anaerobic Thermotoga mar
itima strain MSB8 (DSM 3109) and of the newly isolated Thermotoga spec
. strain ZB (DSM 4138) grown on glucose at 78-degrees-C contained the
long-chain polyamines caldopentamine and caldohexamine. Additional uni
dentified long-chain polyamines were present in small amounts. After i
ncreasing the growth temperature from the lower to the upper limit (50
-85-degrees-C), the proportions of long-chain polyamines present in ce
lls of Thermotoga spec. strain ZB increased both in total amounts, as
well as in increasing chain-length, suggesting a significant role in a
daptation to thermophilic growth.
