“…Major polar lipids are phosphatidylcholine, phosphatidylethanolamine and phosphatidylmethylethanolamine. Members of the genus Saccharopolyspora have been isolated from a broad range of habitats, including plant materials [4], soil [5, 6], marine sponge [7], fodder [8], salt lake [9, 10] et al . In this study, another novel species with the type strain E2A T isolated from coral is described.…”

A novel Gram-stain-positive, aerobic, non-motile actinobacterium, designated strain E2AT, was isolated from a coral sample and examined using a polyphasic taxonomic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain E2AT formed a distinct phyletic lineage in the genus Saccharopolyspora and was closely related to S. cavernae CCTCC AA 2012022T (96.4 %) and S. lacisalsi CCTCC AA 2010012T (95.3 %). The isolate grew at 15–35 °C, pH 5–12 and in the presence of 1–16 % (w/v) NaCl. The cell-wall diamino acid was meso-DAP. Major fatty acids identified were iso-C15 : 0, iso-C16 : 0 and C17 : 1 ω8c. The predominant menaquinone was MK-9(H4). The polar lipids detected were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylmethylethanolamine, one unidentified glycolipid, one unidentified phospholipid and one unidentified aminolipid. The genomic DNA G+C content was 68.6 mol%. Based on the data from the polyphasic taxonomic study reported here, strain E2AT represents a novel species within the genus Saccharopolyspora , for which the name Saccharopolyspora coralli sp. nov. is proposed. The type strain is E2AT=(JCM 31844T=MCCC 1A17150T).

“…2). They were frequently reported from coastal sediments and from marine organisms (sponges, tunicates) (Pimentel-Elardo et al 2008;Souza et al 2017;Suksaard et al 2018), in addition to extreme marine habitats such as deep-sea sediments and hypersaline lakes (Lv et al 2014;Jiang et al 2016;Xia et al 2017). A number of Saccharopolyspora species have been also reported as endophytic micro-organism in different plants (Qin et al 2008;Qin et al 2010;Vaddavalli et al 2014).…”

Actinomycetes are a rich source for secondary metabolites with a diverse array of biological activities. Among the various genera of actinomycetes, the genus Saccharopolyspora has long been recognized as a potential source for antibiotics and other therapeutic leads that belong to diverse classes of natural products. Members of the genus Saccharopolyspora have been widely reported from several natural sources including both terrestrial and marine environments. A plethora of this genus has been chemically investigated for the production of novel natural products with interesting pharmacological effects. Therefore, Saccharopolyspora is considered one of the pharmaceutical important genera that could provide further chemical diversity with potential lead compounds. In this review, the literature from 1976 until December 2018 was covered, providing a comprehensive survey of all natural products derived from this genus and their semi-synthetic derivatives along with their biological activities, whenever applicable. Moreover, the biological diversity of Saccharopolyspora species and their habitats were also discussed.

Bioprospecting the bacterial diversity of marine sponges by culture-dependent and culture-independent approaches This study describes the diversity of associated bacterial communities to five marine sponges, and the potential of these microorganisms as producers of bioactive substances with fungicidal properties. Sponges live in symbiosis with microorganisms that have a high ecological interest, evolutionary and biotechnological. However, this microbial system remains poorly understood. To fully understand sponge biology, it is necessary to describe the ecological and evolutionary factors that influence the structure and dynamics of their microbial communities. In this work, it is supported the hypothesis that the taxonomic composition and structure of bacterial communities correlate with phylogenetic relatedness of their corresponding hosts. Bacterial communities associated with the sponges Aplysina fulva, Aiolochroia crassa, Chondrosia collectrix, Didiscus oxeata and Scopalina ruetzleri were examined using the Ion Torrent platform for partial sequencing of the 16S rRNA gene. Seawater surrounding specimens were collected for comparisons. The analysis detected a complex and specific microbial system living in sponges, with the operational taxonomic units dominant classified in the phyla: Acidobacteria, Actinobacteria, Chloroflexi, Proteobacteria and Gemmatimonadetes. Despite sympatric occurrence of the specimens, the studied sponges presented different bacterial compositions that differed from those observed in seawater. However, lower dissimilarities in bacterial communities were clearly observed within sponges from the same phylogenetic group (A. fulva and A. crassa). Isolation of bacteria was done from the sponges D. oxeata and S. ruetzleri. Fifty-six strains were isolated and classified into three phyla: Actinobacteria, Proteobacteria and Firmicutes. Phylogenetic analysis indicated five possible novel bacterial species. Based in a polyphasic taxonomy approach, one of the isolates denominated ASPSP 40 was identified as belonging to a novel species of the genus Saccharopolyspora for which the name, Saccharopolyspora spongiae sp. nov. has been proposed. All bacterial isolates were evaluated by their antagonisms against Pythium species. Two of them, Terrabacter sp. ASPSP 140 and Bacillus sp. ASPSP 434 demonstrated strong potential in inhibiting the following species P. aphanidermatum, P. ultimum and P. graminicola. The bioactive secondary metabolites of both, characterized by LC-MS/MS, were identified as a mixture of cyclic dipepitides belonging to the class of diketopiperazine (DKP). This is the first report of fungicidal activity, and thus the detection of DKP of the genus Terrabacter.
