Comparative genomics and evolutionary insights into zeaxanthin biosynthesis in two novel Flavobacterium species.

ABSTRACT:

Background

During the screening of pigment-producing microbes from domestic sources, 102 yellow- or orange-pigmented bacteria were isolated. Among these, two novel Flavobacterium strains, F. sedimentum SUN046^T and F. fluvius SUN052^T, were identified as zeaxanthin producers. A polyphasic taxonomic characterization, combined with comparative genomic analysis of 45 Flavobacterium species, was conducted to determine their taxonomic positions and explore potential evolutionary relationships in zeaxanthin biosynthesis.

Results

Both strains utilized the mevalonic acid (MVA) pathway and possessed the crt gene cluster (crtB, crtI, crtY/crtY_cd, and crtZ). Strain SUN046^T exhibited unique features in the carotenoid biosynthesis pathway, notabl
