A Gram-stain-negative, rod-shaped and aerobic bacterium, designated CL12T, was isolated from roots of Glycine max (Linn. Merr.) collected from an experimental field in the campus of South China Agricultural University, PR China (22°58'46″S, 110°51'10″E). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CL12T belongs to th...

In the last decade there has been increased interest in the manipulation of rhizosphere microbial communities in soilless systems (hydroponics) through the addition of plant growth promoting microbes (PGPMs) to increase plant nutrition, lower plant stress response, and control pathogens. This method of crop management requires documenting patterns ...

Members of the genus Methylobacter (Mtb) have been identified to be the most dominant methanotrophs in aquatic as well as terrestrial habitats. Methylobacter shows four species with validly published names and these are grouped in two clades based on phylogenetic and genomic comparisons. Mtb luteus and Mtb marinus (synonym: Mtb whittenburyi) belong...

Two actinobacterial strains were isolated from samples collected from the University of Cape Town, South Africa. A third actinobacterial strain was isolated from soil collected in the town of Stellenbosch, South Africa, using a newly-developed Kribbella-selective medium. Analysis of the 16S rRNA genes showed that the three strains belonged to the g...

Cloning natural product biosynthetic gene clusters from cultured or uncultured sources and their subsequent expression by genetically tractable heterologous hosts is an essential strategy for the elucidation and characterisation of novel microbial natural products. The availability of suitable expression hosts is a critical aspect of this workflow....

A Gram-stain negative, aerobic, non-flagellated, rod-shaped bacterium, designated strain SM1810T, was isolated from deep-sea sediment collected from the Southwest Indian Ocean. Strain SM1810T grows at 15-40 °C (optimum, 28 °C), at pH 5.0-9.0 (optimum, pH 6.0-7.0) and with 0-8% (w/v) NaCl (optimum, 1.5%). Phylogenetic analysis of 16S rRNA gene seque...

Salterns are extreme environments, where the high salt concentration is the main limitation to microbial growth, along with solar radiation, temperature and pH. These selective pressures might lead to the acquisition of unique genetic adaptations that can manifest in the production of interesting natural products. The present study aimed at obtaini...

Bacillus subtilis currently encompasses four subspecies, Bacillus subtilis subsp. subtilis, Bacillus subtilis subsp. inaquosorum, Bacillus subtilis subsp. spizizenii and Bacillus subtilis subsp. stercoris. Several studies based on genomic comparisons have suggested these subspecies should be promoted to species status. Previously, one of the main r...

Zygosaccharomyces seidelii, a new species in the genus Zygosaccharomyces is described. The description of the species is based on a single strain that was isolated from flowers collected on the Maldives. On this occasion, the description of yeast species from single strains was revisited. Sequence analysis of the D1/D2 domain of the nuclear large s...

Tremella fuciformis is an edible and medicinal white jelly mushroom. It has a life cycle that interacts with its companion fungus Annulohypoxylon stygium, both in natural conditions and artificial cultivation. RNA sequencing (RNA-Seq) was used to study the interaction between T. fuciformis and A. stygium by constructing 5 libraries, including the i...
