Complete genome sequence and nitrogen metabolic potential of Stutzerimonas frequens GUA-1 isolated from coastal sediment.

Abstract

Marine and nearshore sediments are nutrient-limited and redox-variable habitats that harbor microorganisms with diverse metabolic adaptations. Here, we report the genome characteristics and nitrogen metabolic potential of Stutzerimonas frequens GUA-1, a bacterium with denitrification-related genes isolated from coastal sediment in Liaoning, China. The genome of GUA-1 was assembled into a single chromosome of 4,523,028 bp with a GC content of 63.70%, predicting 4275 genes, including 4203 protein-coding genes, 60 tRNA genes, and 12 rRNA genes. This genome provides a strain-level reference for coastal sediment-associated Stutzerimonas and highlights the genetic potential for nitrate transformation and carbon conservation under nutrient-limited conditions.
