Metagenome-Assembled Genome of a Putative Chemoheterotroph from Volcanic Terrain in Hawaii.

Here, we present the draft genome for a new putative species, Gaiellasilicea maunaloa, most closely related to Gaiella occulta, within the phylum Actinobacteria. This group contains Gram-negative, aerobic mesophilic species. This metagenome-assembled genome (MAG) contributes to knowledge of life in volcanic environments and may inform investigations of life beyond Earth.

Basaltic Lava Tube Hosts a Putative Novel Genus in the Family Solirubrobacteraceae.

We report the draft genome sequence of a putative new genus and species, Siliceabacter maunaloa, in the family Solirubrobacteraceae. The members of this family of Actinobacteria are generally Gram positive and mesophilic. Found within a Hawaiian lava tube, this microbe illuminates the types of prokaryotes inhabiting secondary minerals in subsurface basaltic environments.
