Abstract: Objectives Microorganisms inhabiting cold and oligotrophic aquatic environments experience persistent physiological stress, necessitating genomic characterization to understand their survival strategies. Psychrotolerant strains have evolved diverse metabolic adaptations, including secondary metabolite biosynthesis, which may contribute to environmental fitness and offer potential for low-temperature biotechnological applications. However, the genus Lacisediminihabitans remains poorly represented at the genomic level, limiting our understanding of its ecological roles and metabolic potential. To address this gap, we generated a high-quality complete genome of a psychrotolerant Lacisediminihabitans strain isolated from Antarctic freshwater. Data description Lacisediminihabitans sp. FW035 grew at 2 − 25 °C with an optimum at 20 °C. The genome of strain FW035 is 3,842,169 bp in size with a G+C content of 66.4%, encoding 3,592 protein-coding genes. Genome analysis revealed a complete C5–C20 isoprenoid biosynthesis pathway and multiple biosynthetic gene clusters, including terpene-associated clusters with low similarity to previously characterized pathways. These features indicate the presence of biosynthetic potential distinct from previously characterized pathways, particularly terpene-associated clusters, and highlight the dataset as a resource for future comparative genomic and functional analyses.
