A pan-genomic assessment: Delving into the genome of the marine epiphyte strain 19_A and other very close strains from multiple environments.

Marine macroalgae are the habitat of epiphytic bacteria and provide several conditions for a beneficial biological interaction to thrive. Although is one of the most abundant epiphytic genera, genomic information on marine macroalgae-associated species remains scarce. In this study, we further investigated our previously published genome of the epiphytic strain 19_A to find features that could be translated to potential metabolites produced by this microorganism, as well as genes that play a role in its interaction with its macroalgal host.

Genome of the epiphytic bacterium strain EPI24, isolated from a macroalga located in the Colombian Caribbean.

Marine macroalgae are being recognized as reservoirs of biologically active compounds, as their surfaces are susceptible to the colonization of microorganisms which can produce enzymes with a wide range of molecular architectures. Among these bacteria, is responsible for the biosynthesis of laccases. In this research, we performed a bioinformatic pipeline to annotate the sequenced complete genome of the epiphytic bacterium strain EPI24, from the macroalgal surface of the species; this strain showed laccase activity which has been previously assessed on plate assays.

Genome sequence of the epiphytic bacteria strain 19_A, isolated from the marine macroalga .

Microorganisms living on marine macroalgal surfaces require enzyme repertoires to metabolize macroalgal-synthesized compounds. These enzymes are biological catalysts which have specific functional properties for biotechnological applications. Here, we raise awareness on the set of enzyme categories produced by the strain 19_A, isolated from the marine macroalga as revealed by the analysis of its complete genome sequence.

Temporal Changes of the Epiphytic Bacteria Community From the Marine Macroalga Ulva lactuca (Santa Marta, Colombian-Caribbean).

Microbial communities live on macroalgal surfaces. The identity and abundance of the bacteria making these epiphytic communities depend on the macroalgal host and the environmental conditions. Macroalgae rely on epiphytic bacteria for basic functions (spore settlement, morphogenesis, growth, and protection against pathogens).
