Evaluation of probiotic properties and complete genome analysis of lactic acid bacteria isolated from crested ibis <i>Nipponia nippon</i> feces.

ABSTRACT:

Introduction

Crested ibis (Nipponia nippon) is a rare bird whose intestinal tract is rich in lactic acid bacteria (LAB), but there is less research on LAB isolated from crested ibises.

Methods

From the fecal samples, Twenty isolates were obtained from fecal samples and subjected to a series of tests, including biochemical identification, acid and bile tolerance assays, in vitro pathogen inhibition, cell surface hydrophobicity assessment, antibiotic susceptibility testing, and hemolytic activity evaluation to determine their probiotic potential. We fed L. plantarum E7 to mice to evaluate safety. Nanopore PromethION48 and the Illumina Novaseq sequencing platforms were used to sequence the genome of L. plantarum E7.

Results

Five isolates (D1,
