Barrientosiimonas endolithica sp. nov., isolated from pebbles, reclassification of the only species of the genus Tamlicoccus, Tamlicoccus marinus Lee 2013, as Barrientosiimonas marina comb. nov. and emended description of the genus Barrientosiimonas

Abstract

Strain JC268T was isolated from pebbles collected from a dam located in Lalitpur, Uttar Pradesh, India. Cells of strain JC268T were coccoid, appeared in pairs/triads/tetrads or short chains and were Gram-stain-positive, non-spore-forming, non-motile and obligately aerobic. Strain JC268T was catalase- and oxidase-positive and utilized citrate for growth. The genomic DNA G+C content of strain JC268T was 65.3 mol%. The cell-wall peptidoglycan contained l-lysine–l-serine–d-aspartic acid as interpeptide bridge with the type A4α. The major menaquinone was MK-8(H4). Major (>10 %) fatty acids were iso-C16 : 0, iso-C16 : 1H and anteiso-C17 : 1ω9c. Diphosphatidylglycerol, phosphoglycolipid, phosphatidylinositol, glycolipid, four unidentified lipids, an amino lipid and phospholipid were the polar lipids of strain JC268T. EzTaxon-e blast search of 16S rRNA gene sequences showed that strain JC268T has highest similarity to Barrientosiimonas humi 39T (98.65 %) and Tamlicoccus marinus MSW-24T (97.8 %) of the family Dermacoccaceae. Genome reassociation (based on DNA–DNA hybridization) of strain JC268T with Barrientosiimonas humi CGMCC 4.6864T ( = 39T) and T. marinus KCTC 19485T ( = MSW-24T) yielded values of 32.5 ± 2 % and 27.3 ± 2 %, respectively. Based on the data from phylogenetic and polyphasic taxonomic analyses, strain JC268T represents a novel species of the genus Barrientosiimonas for which the name Barrientosiimonas endolithica sp. nov., is proposed. The type strain of Barrientosiimonas endolithica is JC268T ( = KCTC 29672T = NBRC 110608T). Our data suggest that T. marinus should be reclassified within the genus Barrientosiimonas. Thus, a reclassification is proposed for T. marinus, the type and only species of the genus Tamlicoccus, as Barrientosiimonas marina comb. nov., which implies the emendation of the description of the genus Barrientosiimonas.

Production and Characterization of Extremophilic Proteinases From a New Enzyme Source, Barrientosiimonas sp. V9

“…Thus, the ability to produce enzymes may be an attractive source among such prokaryotic organisms. Currently, the family Dermacoccaceae (www.bacterio.net/-classifphyla.html#dermacoccaceae) comprises 11 genera, including the genus Barrientosiimonas that contains 3 species, B. endolithica, B. marina [12], and B. humi [13]. Information about the genus Barrientosiimonas is very scarce in the scientific literature.…”

“…scopus.com) databases generate only 3 and 4 references, respectively. These studies include taxonomical [12,13] or microbial ecology [14,15] approaches, but none explore the biotechnological potential of this genus. Therefore, the aim of this work was to investigate the production of extracellular proteases by Barrientosiimonas sp.…”

Leekyejoonella antrihumi gen. nov., sp. nov., a new member of the family Dermacoccaceae isolated from a cave soil

“…In 2017, the genus Allobranchiibius was described as a new member of the family Dermacoccaceae [11]. The genus Tamlicoccus [12], which has been described as a member of this family, was transferred to the genus Barrientosiimonas [13]. In the recently emended description of the family Dermacoccaceae based on genome-based taxonomic classification [14], the genus Kytococcus was removed from this family and moved to be the type genus of a new family 'Kytococcaceae' .…”
