海洋固氮蓝藻Trichodesmiumspp. Trichodesmiums在盐度为27 - 43 ppm 2的环境中生长,但其盐适应策略仍然是个谜,因为Trichodesmiums的菌株IMS 101的基因组缺少所有已知相容溶质的生物合成基因。利用核磁共振和液相色谱-质谱联用技术,鉴定了黑曲霉菌株IMS 101的主要相容性溶质为季铵化合物N,N,N-三甲基高丝氨酸(或高丝氨酸甜菜碱),并阐明了其生物合成途径。这种相容性溶质的鉴定解释了Trichodesmiumspp.可以在不同盐度的海洋系统中茁壮成长,并进一步了解微生物盐驯化的多样性。
The oceanic N2-fixing cyanobacteriumTrichodesmiumspp. form extensive surface blooms and contribute significantly to marine carbon and nitrogen cycles in the oligotrophic subtropical and tropical oceans.Trichodesmiumgrows in salinities from 27 to 43 parts per thousand (ppt), yet its salt acclimation strategy remains enigmatic because the genome ofTrichodesmium erythraeumstrain IMS101 lacks all genes for the biosynthesis of any known compatible solute. Using NMR and liquid chromatography coupled to mass spectroscopy, we identified the main compatible solute inT. erythraeumstrain IMS101 as the quaternary ammonium compoundN,N,N-trimethyl homoserine (or homoserine betaine) and elucidated its biosynthetic pathway. The identification of this compatible solute explains howTrichodesmiumspp. can thrive in the marine system at varying salinities and provides further insight into the diversity of microbial salt acclimation.
