Actinobacteria isolated from unstudied ecosystems are one of the most interesting and promising sources of novel biologically active compounds. Cave ecosystems are unusual and rarely studied. Here, we report the isolation and characterization of ten new actinobacteria strains isolated from an ancient underground lake and moonmilk speleothem from the biggest conglomeratic karstic cave in Siberia...

Oxidative enzymes are often considered for use in industrial processes because of the variety of reactions they are able to catalyse. In the past, most of these oxidative en‐ zymes were obtained from fungi. However, in recent years, it has become evident that these enzymes are also produced by bacteria, including actinobacterial strains, which can therefore be considered as an underexploited re...

Phylogenetic analyses of the SSU rRNA sequences of representatives of the phylum Actinobacteria were performed to identify the major taxonomic groups. The current release of the integrated small subunit rRNA database of the SILVA project [1] provided the sequences. The tools of the ARB software package [2] were used for data evaluation, optimization and phylogenetic inference. The alignment of ...

Conjugation is certainly the most widespread and promiscuous mechanism of horizontal gene transfer in bacteria. During conjugation, DNA translocation across membranes of two cells forming a mating pair is mediated by two types of mobile genetic elements: conjugative plasmids and integrating conjugative elements (ICEs). The vast majority of conjugative plasmids and ICEs employ a sophisticated pr...

Analysis of the fatty acid composition total cellular lipids is important chemotaxonomic characteristic that used to identify microorganisms, in particular actinobacteria, with help spectra libraries. Actinobacteria are well known as producers secondary metabolites, which pharmacological and commercial interest. A significant number actinomycetes associated various marine benthic communities. T...

Globally the change towards the establishment of a bio-based economy has resulted in an increased need for bio-based applications. This, in turn, has served as a driving force for the discovery and application of novel biosurfactants. The class Actinobacteria represents a vast group of microorganisms with the ability to produce a diverse range of secondary metabolites, including surfactants. Un...

This is a commentary on the research article by Lu et al. recently published in Bioscience Reports The GCN5-like acetyltransferases with amino acid-binding (ACT)-GCN5-related N-acetyltransferase (GNAT) domain organization have been identified in actinobacteria by Lu et al. (2017). The ACT domain is fused to the GNAT domain, conferring amino acid-induced allosteric regulation to these protein ac...

In order to find new actinomycete resources for discovering new drug leads, the actinomycete associated with lichens was studied. Three species of lichen samples were collected from 3 locations of Yunnan. Actinomycetes in the samples were isolated with 11 media, and identified with 16S rRNA gene sequence procedures. Bacteria of two of the three species were sequenced by using 454 pyrosequencing...

UNLABELLED The genomes of four novel marine Actinobacteria have been assembled from large metagenomic data sets derived from the Mediterranean deep chlorophyll maximum (DCM). These are the first marine representatives belonging to the order Acidimicrobiales and only the second group of planktonic marine Actinobacteria to be described. Their streamlined genomes and photoheterotrophic lifestyle s...
