title: Draft genomes of Nautella italica strains CECT 7645(T) and CECT 7321: Two roseobacters with potential pathogenic and biotechnological traits.
abstract: Nautella italica is a member of the family Rhodobacteraceae described in 2009. Strain LMG 24365(T) (=CECT 7645(T), =DSM 26436(T), =CCUG 55857(T)) was isolated from a marine electroactive biofilm growing in a stainless steel cathode exposed to natural water in Genoa, Italy. Strain AD 41 (=CECT 7321) was isolated from water surrounding cultivated gilthead seabream larvae in Cádiz, Spain. The genomes of strains CECT 7645(T) and CECT 7321 were sequenced, assembled, annotated and compared. Here we describe the most relevant findings: biofilm formation, quorum sensing, resistance to multiple drugs, heavy metals and oxidative stress, cytotoxins, and poly-β-hydroxybutyrate (PHB) production genes. These genomes were also compared to current available genomes in NCBI Genome Database from members of the genus Nautella, Nautella sp. R11 and Nautella sp. ECSMB14104. The comparison showed a higher similarity between strains CECT 7645(T) and R11 compared to strain CECT 7321 and strain ECSMB14104. The genome similarity indexes allowed confirming and assigning strains CECT 7321, R11 and ECSMB14104 to the species N. italica.
