“…From 2005 to date, several novel genera of the so-called rare Actinobacteria have been discovered from marine environments, of which 13 of them have been isolated from marine sediments. These include Salinispora (Maldonado et al, 2005a ), Demequina (Yi et al, 2007 ), Aestuariimicrobium (Jung et al, 2007 ), Sciscionella (Tian et al, 2009b ), Marinactinospora (Tian et al, 2009a ), Paraoerskovia (Khan et al, 2009 ), Marisediminicola (Li et al, 2010 ), Miniimonas (Ue et al, 2011 ), Spinactinospora (Chang et al, 2011 ), Sediminihabitans (Hamada et al, 2012 ), Flaviflexus (Du et al, 2013 ), Mariniluteicoccus (Zhang et al, 2014a ), and Halopolyspora (Lai et al, 2014 ). Rare Actinobacteria are considered to be those strains that are less likely to be cultivated by conventional methods (Lazzarini et al, 2001 ; Baltz, 2006 ).…”

Marine-derived Actinobacteria are a source of a broad variety of secondary metabolites with diverse biological activities, such as antibiotics and antitumorals; many of which have been developed for clinical use. Rare Actinobacteria represent an untapped source of new bioactive compounds that have been scarcely recognized. In this study, rare Actinobacteria from marine sediments were isolated from the Valparaíso bay, Chile, and their potential to produce antibacterial compounds was evaluated. Different culture conditions and selective media that select the growth of Actinobacteria were used leading to the isolation of 68 bacterial strains. Comparative analysis of the 16S rRNA gene sequences led to identifying isolates that belong to the phylum Actinobacteria with genetic affiliations to 17 genera: Aeromicrobium, Agrococcus, Arthrobacter, Brachybacterium, Corynebacterium, Dietzia, Flaviflexus, Gordonia, Isoptericola, Janibacter, Microbacterium, Mycobacterium, Ornithinimicrobium, Pseudonocardia, Rhodococcus, Streptomyces, and Tessaracoccus. Also, one isolate could not be consistently classified and formed a novel phylogenetic branch related to the Nocardiopsaceae family. The antimicrobial activity of these isolates was evaluated, demonstrating the capability of specific novel isolates to inhibit the growth of Gram-positive and Gram-negative bacteria. In conclusion, this study shows a rich biodiversity of culturable Actinobacteria, associated to marine sediments from Valparaíso bay, highlighting novel rare Actinobacteria, and their potential for the production of biologically active compounds.

“…The family Beutenbergiaceae was proposed by Zhi et al . [1] as a member of the order Micrococcales within the class Actinobacteria and currently comprises the genera Beutenbergia [2], Miniimonas [3], Salana [4] and Serinibacter [5]. The genus Serinibacter is composed of two species with validly published names [5, 6], while the others are monospecific genera.…”

A novel actinobacterium, designated HIsM16-52 T , was isolated from beach sand collected from Ishigaki Island in Japan and its taxonomic position was investigated by a polyphasic approach. Strain HIsM16-52 T contained both lysine and ornithine as the diagnostic diamino acids of the peptidoglycan. The predominant isoprenoid quinone was MK-8(H 4) and the major fatty acids were anteiso-C 15 : 0 , C 16 : 0 and C 14 : 0. The detected polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and two unidentified phospholipids. The DNA G+C content was determined to be 73.4 mol%. Phylogenetic analyses based on 16S rRNA gene sequence comparison revealed that strain HIsM16-52 T fell within the cluster of the family Beutenbergiaceae and formed a reliable cluster with the members of the genus Serinibacter. The highest 16S rRNA gene sequence similarities were obtained to species of the genus Serinibacter (97.8-97.9 %), followed by the genera Miniimonas (97.0 %), Beutenbergia (96.4 %) and Salana (95.9 %). However, strain HIsM16-52 T differed from the members of the genus Serinibacter and the other genera within the family Beutenbergiaceae in terms of chemotaxonomic characteristics. Therefore, strain HIsM16-52 T is concluded to represent a novel genus and species of the family Beutenbergiaceae, for which the name Litorihabitans aurantiacus gen. nov., sp. nov. is proposed. The type strain of L. aurantiacus is HIsM16-52 T (=NBRC 112290 T =TBRC 7759 T).
