Characterization of mycosporine-like amino acids in the edible cyanobacterium Nostoc commune (Di Pi Cai) from China.
The terrestrial cyanobacterium Nostoc commune has a cosmopolitan distribution. It is edible, and dry thalli are sold as a food in China under the name of Di Pi Cai. The pigment composition and the genotypes were characterized to identify the cyanobacterium Di Pi Cai from China as N. commune. Myxol glycosides and ketocarotenoids were detected, as expected in Nostoc sp., but β-carotene and hydroxylated carotenoids were not detected. Nostoc-756, mycosporine-2-(4-deoxygadusoyl-ornitine), was found to be a main mycosporine-like amino acid, which indicates that Di Pi Cai belongs to the N. commune chemotype C. However, the 16S rRNA gene and the petH gene encoding ferredoxin-NADP+ oxidoreductase of Di Pi Cai did not exactly match those of genotype C found in Japan. These results suggest the unique molecular genetic features of Di Pi Cai and the global diversity of N. commune.
