利用软X射线显微镜观察了丝状蓝藻Anabaena sp. PCC 7120的营养细胞和异形胞。通过氮K边吸收以下和以上的图像的吸光度的差异来估计每个细胞的碳氮比（C/N）。营养细胞和异形胞的C/N分别为4.54和2.46。
Vegetative cells and heterocysts in the filamentous cyanobacterium Anabaena sp. PCC 7120 were observed by soft X-ray microscopy. Carbon-to-nitrogen (C/N) ratio of each cell was estimated by the difference of the absorbance of the images below and above the nitrogen K-edge absorption. It was revealed that the C/N ratios in vegetative cells and heterocysts are 4.54 and 2.46, respectively.
