“…Polymorphospora is a genus in Micromonosporaceae , and Polymorphospora strains were mainly isolated from soil surrounding mangrove roots (Tamura et al, 2006 ). Marihabitans is a genus in Intrasporangiaceae (Kageyama et al, 2008 ). Notably, the genus is quite rare and only one strain was previously cultured from surface seawater (Kageyama et al, 2008 ).…”

Marine sponges often harbor dense and diverse microbial communities including actinobacteria. To date no comprehensive investigation has been performed on the culturable diversity of the actinomycetes associated with South China Sea sponges. Structurally novel aromatic polyketides were recently discovered from marine sponge-derived Streptomyces and Saccharopolyspora strains, suggesting that sponge-associated actinomycetes can serve as a new source of aromatic polyketides. In this study, a total of 77 actinomycete strains were isolated from 15 South China Sea sponge species. Phylogenetic characterization of the isolates based on 16S rRNA gene sequencing supported their assignment to 12 families and 20 genera, among which three rare genera (Marihabitans, Polymorphospora, and Streptomonospora) were isolated from marine sponges for the first time. Subsequently, β-ketoacyl synthase (KSα) gene was used as marker for evaluating the potential of the actinomycete strains to produce aromatic polyketides. As a result, KSα gene was detected in 35 isolates related to seven genera (Kocuria, Micromonospora, Nocardia, Nocardiopsis, Saccharopolyspora, Salinispora, and Streptomyces). Finally, 10 strains were selected for small-scale fermentation, and one angucycline compound was detected from the culture extract of Streptomyces anulatus strain S71. This study advanced our knowledge of the sponge-associated actinomycetes regarding their diversity and potential in producing aromatic polyketides.

“…The family Intrasporangiaceae was proposed by Stackebrandt et al (1997) and currently contains 18 genera. Recently, the following new genera have been assigned to this family on the basis of the results of chemotaxonomic and phylogenetic analyses: Humibacillus (Kageyama et al, 2008a), Humihabitans (Kageyama et al, 2007), Lapillicoccus (Lee & Lee, 2007), Marihabitans (Kageyama et al, 2008b) and Fodinibacter (Wang et al, 2009). The genus Arsenicicoccus was also proposed as a member of the family Intrasporangiaceae with a single species, Arsenicicoccus bolidensis (Collins et al, 2004).…”

A Gram-positive bacterium, designated strain Kis4-19 T , was isolated from the intestinal tract of a fish, and its taxonomic position was investigated by a polyphasic approach. The cells of strain Kis4-19 T were coccus-shaped, non-motile and non-sporulating. The peptidoglycan type of this organism was A3; LL-diaminopimeric acid (LL-A 2 pm) was the diagnostic diamino acid of the peptidoglycan. The predominant menaquinone was MK-8(H 4 ), and the major fatty acids were iso-C 15:0 , iso-C 14:0 and iso-C 16:0 . Galactose was detected as a cell-wall sugar. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and lyso-phosphatidylethanolamine. The DNA G+C content was 71.1 mol%. Sequencing analysis of the 16S rRNA gene indicated that strain
