The comparison of the predominant bacterial community structure in the gastrointestinal walls between Lutjanus sebae (Cuvier, 1816) and Ephippus orbis (Bloch, 1787) based on 16S rDNA PCR-DGGE fingerprint using a culture-independent method was conducted in the paper. The results showed that abundant bacterium were planted in the gastrointestinal walls of both marine finfish species, the similarity was above 50% in the community structures in the gastrointestinal walls with the highest similarity of 67% in the bacterial composition between the intestinal wall of Luljonus sebae and that of Ephippus orbis, and the walls of the stomach and the intestinal in one fish shared the same most predominant bacteria species, which might reflect the same aquaculture environment and the diet fed for both finfish species.

本文采用免培养的16S rDNA梯度凝胶电泳技术对集约化海水网箱养殖川纹笛鲷Lutjanus sebae、及圆白鲳Ephippus orbis消化道壁优势菌群结构进行了比较分析研究结果显示川纹笛鲷及圆白鲳消化道壁存在着大量细菌群落，对DGGE指纹图谱聚类分析表明两种鱼肠道壁及胃壁菌群组成相似度高于50%，其中二者肠道壁细菌组成相似性最高(67%)，这些可能与两种鱼养殖在同一水域、摄食相同饵料相关，另外通过软件对DGGE指纹带谱相对丰度分析表明同种鱼肠道壁及胃壁具有相同最大优势菌群。
