Triamines such as norspermidine, spermidine, and homospermidine and tetraamines such as norspermine, spermine, thermospermine, and aminopropylhomospermidine were found to be distributed ubiquitously in the eight extremely thermophilic (growing at 70 degrees C) Thermus species tested. Three linear pentaamine (caldopentamine, homocaldopentamine, and thermopentamine), two linear hexaamines (caldohexamine and homocaldohexamine), two tertiary branched tetraamines (N4-aminopropylnorspermidine and N4-aminopropyl-spermidine), and quaternary branched pentaamines such as N4-bis(aminopropyl)norspermidine and N4-bis(aminopropyl)spermidine were detected in T. thermophilus HB8, T. filiformis Wai33 A1, T. flavus AT-62, and T. caldophilus GK24. The linear hexaamines and branched polyamines were absent in T. aquaticus YT-1, T. sp. X-1, T. sp. T2, and T. sp. T351, in which linear pentaamines were minor components. Moderately thermophilic Thermus ruber and Thermus sp. K-2 contained putrescine, spermidine, norspermidine, homospermidine, spermine, norspermine, thermospermine, and aminopropylhomospermidine. No pentaamines, hexaamines, or branched polyamines were found in these two moderately thermophilic Thermus species. On the other hand, moderately thermophilic, acidophilic Acidothermus cellulolyticus was devoid of all the polyamines.
已发现，诸如亚精胺、精胺和高亚精胺之类的三胺以及诸如亚精胺、精胺、热精胺和氨丙基高亚精胺之类的四胺普遍存在于所测试的8种极端嗜热（在70摄氏度生长）栖热菌属物种中。在嗜热栖热菌HB8、丝状栖热菌Wai33 A1、黄栖热菌AT - 62和嗜热栖热菌GK24中检测到三种直链五胺（热戊胺、高热戊胺和热戊胺）、两种直链六胺（热己胺和高热己胺）、两种叔胺支链四胺（N4 - 氨丙基亚精胺和N4 - 氨丙基精胺）以及季胺支链五胺，如N4 - 双（氨丙基）亚精胺和N4 - 双（氨丙基）精胺。直链六胺和支链多胺在嗜热水栖菌YT - 1、栖热菌属X - 1、栖热菌属T2和栖热菌属T351中不存在，在这些菌株中直链五胺是次要成分。中度嗜热的红栖热菌和栖热菌属K - 2含有腐胺、亚精胺、亚精胺、高亚精胺、精胺、亚精胺、热精胺和氨丙基高亚精胺。在这两种中度嗜热的栖热菌物种中未发现五胺、六胺或支链多胺。另一方面，中度嗜热、嗜酸的解纤维素嗜热栖酸菌不含所有这些多胺。
