sp. nov., an actinobacterium isolated from stony coral in the South China Sea.

A Gram-stain-positive, aerobic, non-pigmented and non-motile actinobacterium, designated strain SCSIO 67246, was isolated from a stony coral sample collected from the Sanya sea area, Hainan province, China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SCSIO 67246 shared the highest similarities with MCCC 1A10561 (96.5 %) and KCTC 39565 (96.

sp. nov., a thermophilic bacterium isolated from deep sea sediment in the South China Sea.

A novel thermophilic bacterium, designated SCSIO 07484, was isolated from marine sediment sampled in the South China Sea. Growth occurred at 30-60 °C, pH 6.0-8.

Diversity and Distribution of Uncultured and Cultured Gaiellales and Rubrobacterales in South China Sea Sediments.

Actinobacteria are ubiquitous in marine ecosystems, and they are regarded as an important, underexplored, potential pharmaceutical resource. The orders Gaiellales and Rubrobacterales are deep taxonomic lineages of the phylum Actinobacteria, both are represented by a single genus and contain only a few species. Although they have been detected frequently by high-throughput sequencing, their functions and characteristics in marine habitats remain unknown due to the lack of indigenous phenotypes.

Miltoncostaea marina gen. nov. sp. nov., and Miltoncostaea oceani sp. nov., a novel deep branching phylogenetic lineage within the class Thermoleophilia isolated from marine environments, and proposal of Miltoncostaeaceae fam. nov. and Miltoncostaeales ord. nov.

Two novel marine actinobacteria, designated as SCSIO 60955 and SCSIO 61214, were isolated from deep-sea sediment samples collected from the South China Sea. The cells of these organisms stained Gram-negative and were rod shaped. These strains were aerobic, and catalase- and oxidase-positive.

sp. nov. and sp. nov., isolated from deep-sea sediment of the South China Sea.

Two novel Gram-stain-positive bacteria, designated as SCSIO 52909 and SCSIO 52915, were isolated from a deep-sea sediment sample collected at about 3448 m water depth of the South China Sea. Phenotypic, chemotaxonomic and genomic characteristics were investigated. These strains were aerobic and tested positive for catalase activity, oxidase activity and nitrate reduction.

gen. nov. sp. nov., a new marine actinobacterium of the family , isolated from South China Sea sediment environments.

A novel marine actinobacterium, strain SCSIO 58843, was isolated from the sediment sample collected from the South China Sea. Strain SCSIO 58843 was Gram-stain-positive, aerobic and rod shaped. The whole-cell hydrolysis of amino acids contained dd-DAP, alanine, glutamic acid, glycine and aspartic acid.
