Project description:Microplastics (MPs) as widespread contamination pose high risk for aquatic organisms.Intestinal microbiotahas have high interaction with immune system of host body. In this study, intestinal microbiota of zebrafish after Polystyrene (PS-MPs) exposure were characterized by 16S rDNA amplicon sequencing. We found that 100nm and 200μm PS-MPs exposure significantly increased diversity of intestinal microbiota and all the three sizes of PS-MPs increased abundance of pathogenic bacteria.
Project description:This study evaluated the biocontrol efficacy, growth-promoting potential, and molecular mechanisms of the actinomycete strain FJSM-07, identified via 16S rDNA sequencing as Streptomyces murinus.
Project description:Six- to eight-week old CD1 male mice were sleep-deprived for 24 hours by placing them in a small platform in a water tank. Their ileum samples were harvested every 4 hours on the next day (time point: ZT1,ZT5,ZT9,ZT13,ZT17,ZT21). The ileum samples were subjected to 16s rDNA sequencing. Control group (C1,C5,C9,C13,C17,C21, n=36). SD group (SD1,SD5,SD9,SD13,SD17,SD21, n=36).
Project description:Prostate of SD rats was injected with 0.1 ml 1% carrageenan to induce chronic nonbacterial prostatitis, and the control rats injected with sterile saline. Then, the cecal contents were collected for 16S rDNA sequencing.
