Fig. (1) T-RFLP profiling of the cyanobacterial 16S rRNA gene amplified as template total DNA of the gastric content of dead egrets. KS2P (A) and KS4P (B) were used for PCR amplification. HaeIII was used for digestion. The x-axis indicates the terminal restriction fragment length (bases) between 0 and 700 bases, and the y-axis represents the relative height of the peak. The highest peak was calculated as 1. A relative height of over 0.1 showed the T-RF length.
