## TL;DR

This paper reports the full genome sequence of a new Sphingobium yanoikuyae strain that can produce beta-carotene and degrade harmful substances.

## Contribution

The study provides the complete genomic sequences of a novel Sphingobium yanoikuyae strain with unique metabolic capabilities.

## Key findings

- The complete genome sequence includes a single chromosome and four putative plasmids.
- The strain is capable of beta-carotene synthesis, xenobiotic degradation, and heavy metal tolerance.
- The genomic data offers insights into the strain's metabolic and phylogenetic characteristics.

## Abstract

A novel Sphingobium yanoikuyae strain, CC4533, was isolated from a contaminated tris-acetate-phosphate medium culture plate of a green microalga, Chlamydomonas reinhardtii. In this study, we present the complete genome sequence of this beta-carotene-synthesizing, xenobiotic-degrading, and heavy metal-tolerant strain, providing insights into its metabolic capabilities and phylogenetic relationships.
