The Gut Microbial Community of Antarctic Fish Detected by 16S rRNA Gene Sequence Analysis
Intestinal bacterial communities are highly relevant to the digestion, nutrition, growth, reproduction, and a range of fitness in fish, but little is known about the gut microbial community in Antarctic fish. In this study, the composition of intestinal microbial community in four species of Antarct...
