Metagenomic analysis of gut microbiota in Pacific white shrimp (Penaeus vannamei) juveniles treated with a multi-strain probiotic consortium
This study examines effects of a mixed probiotic consortium on gastrointestinal microbiota of Pacific white shrimp Penaeus vannamei. Juvenile shrimp received probiotics via culture water at 10^6 CFU per mL for 40 days. Gastrointestinal samples were collected and analyzed by 16S rRNA gene sequencing V3-V4 region using Illumina MiSeq. The study characterizes probiotic-induced microbiota changes and associations between microbial community structure and shrimp growth performance.
