Streszczenie:

Plastisitas morfologi sponge telah lama menjadi tantangan berat dalam identifikasi jenis sponge dan mempunyai implikasi penting di bidang konservasi spesies, penemuan bahan bioaktif maupun biomaterial berpotensi medis dari invertebrata laut ini. Peran ekologis, kandungan senyawa bioaktif maupun variasi genetik dari X. testudinaria, sponge ikonik di terumbu karang Sulawesi Utara dan Indo-Pasifik ini, telah seringkali dilaporkan. Tetapi penelitian tentang plastisitas X. testudinaria masih sangat terbatas. Untuk menentukan plastisitias X. testudinaria dari Kabupaten Sitaro dan Sangihe, kami membandingkan karakteristik morfologi (contoh, warna, bentuk pertumbuhan, permukaan tubuh, ukuran dan bentuk spikula). Sejauh ini, tiga morfotipe sponge jenis Xestospongia testudinaria telah ditemukan di Kepulauan Sitaro dan Sangihe; (1) morfotipe digitate di Pulau Mahumu, (2) morfotipe lamellate di perairan Enepahembang dan Bebalang dan (3) morfotipe licin di Ulu Siau. Berbeda dengan studi plastisitas X. testudinaria sebelumnya, penelitian kami tidak menunjukkan adanya dominasi dari salah satu morfotipe ini di wilayah di sekitar pelabuhan laut dan daerah dengan masukan sedimentasi tinggi. Kami juga membahas implikasi dari penelitian ini untuk mendapatkan gambaran lebih baik mengenai distribusi berbagai morfotipe X. testudinaria di perairan Nusa Utara. Morphological plasticity in sponge has become a serious challenge in sponge identification and has an important implication in species conservation. Ecological roles, bioactive compounds, and genetic variation of X. testudinaria, the iconic sponge from the coral reef in North Sulawesi and even Indo-Pacific, have been frequently reported. However, research on the plasticity of X. testudinaria remains limited. To determine the plasticity of this species from Sitaro and Sangihe Islands, we compared the morphological characteristics (e.g. color, growth form, surface, size and the style of spicule). So far, three morphotypes of X. testudinaria have been found in Sitaro and Sangihe Island regencies; digitate, lamellate and smooth surfaces. Different from earlier study on plasticity in X. testudinaria, our research did not show domination of any morphotype in areas near seaport and high sedimentation. We also discussed the implication of this research to get a better understanding of the distribution of X. testudinaria with different morphotypes in Nusa Utara waters.

The aim of this study is to isolate and characterize the structure of metabolite compounds of the sponge Xestospongia testudinaria, which grows in West Kalimantan. 3000 grams of sponges were analyzed through a preparation and extraction process, which produced a methanol-dissolved extract with a mass of 77.2 grams. The methanol-dissolved extract of was parted using n-hexane and dichloromethane as solvents. Based on the results of phytochemical testing, it can be concluded that the dissolved fraction of dichloromethane contains alkaloids and terpenoids or steroids. The purification process was carried out on 2.4 grams of dichloromethane-dissolved fraction by means of vacuum liquid chromatography, and ten separation fractions were obtained with eluated ethyl acetate : n-hexane as eluent. The separation fractions of FD 3, FD 4, FD 5 and FD 6, which have the same chromatogram characteristics were combined to be purified by means of preparative chromatography. The preparative process was carried out with chloroform : methanol 98:2 eluent, and three chromatogram isolates were produced. The chromatogram isolates with Rf = 0.44 and a mass of 8 milligrams were analyzed by FTIR spectroscopy using pellet KBr and 1H-NMR spectroscopy using CD3OD solvent. Based on the results of data analysis, it is concluded that the predicted content of metabolite compound of the Xestospongia testudinaria sponge sample growing in West Kalimantan waters is propyl-6,7,8-trihydroxy-4-pentadecenoate compound, which is a compound of the fat or lipid ester group with a typical IR absorption peak of the C = O group and C – O at wave numbers 1735.93 – 1766.80 cm-1 and 1111.00 – 1315.45 cm-1 and the containing 11 environments of hydrogen atoms scattered in the 1H-NMR chemical shift from 0.85 ppm to 3.97 ppm.

Streszczenie:

Diabetic peripheral neuropathy (DPN) is a common complication of diabetes. Oxidative stress plays an important role in the pathophysiology of DPN. Red Sea marine sponge Xestospongia testudinaria extract has a promising neuroprotective effect, presumably owing to its antioxidant and anti-inflammatory properties. Thus, this study aimed to investigate the neuroprotective effect of the sponge X. testudinaria extract on in vitro and in vivo models of DPN. Mice dorsal root ganglia (DRG) were cultured with high glucose (HG) media and used as an in vitro model of DPN. Some of the DRGs were pre-treated with 2 mg/mL of X. testudinaria. The X. testudinaria extract significantly improved the HG-induced decreased neuronal viability and the neurite length. It improved the oxidative stress biomarkers in DRG cultures. The DPN model was induced in vivo by an injection of streptozotocin at a dose of 150 mg/kg in mice. After 35 days, 0.75 mg/kg of the X. testudinaria extract improved the hot hyperalgesia and the DRG histology. Although the sponge extract did not reduce hyperglycemia, it ameliorated the oxidative stress markers and pro-inflammatory markers in the DRG. In conclusion, the current study demonstrates the neuroprotective effect of Red Sea sponge X. testudinaria extract against experimentally induced DPN through its antioxidant and anti-inflammatory mechanisms.

Aim: The purposes of this study were to determine the anticancer activity of Xestospongia testudinaria sponge isolate and identify the responsible compounds. Materials and Methods: The metabolites were extracted using methanol maceration at room temperature. The separation and purification of metabolites were performed using fractionation and column chromatography. The toxicity was examined using the brine shrimp lethality assay, and the toxic isolates were tested for anticancer activity against HeLa cells. Gas chromatography-mass spectrometry analysis was used to identify the compounds in the isolate. Results: When the methanol extract was partitioned with n-hexane, chloroform, and n-butanol, the chloroform fraction was the most toxic, with a concentration that results in 50% lethality (LC50) value of 39.81 ppm. After separation of the chloroform extract, fraction B (FB) was the most toxic, with an LC50 value of 44.67 ppm. The isolate from FB showed anticancer activity with a concentration at which 50% of growth was inhibited (IC50) of 2.273 ppm. In total, 21 compounds were identified in anticancer isolates: Nonanedioic acid; tetradecanoic acid; trans-phytol; 2-pentadecanone- 6,10,14-trimethyl; pentadecanoic acid; 2-hexadecen-1-ol, 3,7,11,15-tetramethyl-; pentadecanoic acid; 2-hexadecen-1-ol, 3,7,11,15-tetramethyl-; 2,3,7-trimethyloctanal; palmitic acid; docosanoic acid, ethyl ester; 1,E-11,Z-13-octadecatriene; chloromethyl 4-chlorododecanoate; 1-tricosene; 9,12-octadecadienoic acid; 4,8,12,16-tetramethylheptadecan-4-olide; 1-docosene; heneicosane; phosphonic acid, dioctadecyl ester; dodecane,4,6-dimethyl-; n-tetratriacontane; 1-iodohexadecane; and n-heneicosane. Conclusion: These findings indicate that the isolate of X. testudinaria can be used as a natural anticancer toward HeLa cell.

A Gram-negative, catalase- and oxidase-positive, non-sporulating, rod-shaped and slightly halophilic bacterial strain, designated UST090418-1611T, was isolated from the marine sponge Xestospongia testudinaria collected from the Red Sea coast of Saudi Arabia. Phylogenetic trees based on the 16S rRNA gene sequence placed strain UST090418-1611T in the family Alteromonadaceae with the closest relationship to the genus Marinobacter . The 16S rRNA gene sequence similarity between the strain and the type strains of recognized Marinobacter species ranged from 92.9 to 98.3 %. Although strain UST090418-1611T shared high 16S rRNA gene sequence similarity with Marinobacter mobilis CN46T, M. zhejiangensis CN74T and M. sediminum R65T (98.3, 97.4 and 97.3 %, respectively), the relatedness of the strain to these three strains in DNA–DNA hybridization was only 58, 56 and 33 %, respectively, supporting the novelty of the strain. In contrast to most strains in the genus Marinobacter , strain UST090418-1611T tolerated only 6 % (w/v) NaCl, and optimal growth occurred at 2.0 % (w/v) NaCl, pH 7.0–8.0 and 28–36 °C. The predominant cellular fatty acids were C12 : 0 3-OH, C16 : 0, C12 : 0 and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c). The genomic DNA G+C content was 57.1 mol%. Based on the physiological, phylogenetic and chemotaxonomic characteristics presented in this study, we suggest that the strain represents a novel species in the genus Marinobacter , for which the name Marinobacter xestospongiae sp. nov. is proposed, with UST090418-1611T ( = JCM 17469T = NRRL B-59512T) as the type strain.

BACKGROUND: Biosilica derived from Indonesian marine sponge Melophlus sarasinorum and Xestospongia testudinaria is one of the biomaterials that can be developed together with synthetic polymer as a composite. Poly E-caprolactone (PCL) used as a composite role as an osteoconductive material together with biosilica and also tailored the slow rate of degradation in the body. This study aimed to create a biocompatible biosilica-based scaffold and supports osteogenic differentiation of human Wharton's Jelly mesenchymal stem cell (hWJ-MSCs).METHODS: Biosilica was extracted from M. sarasinorum and X. testudinaria with the acid digestion method. Scaffold was prepared using the salt leaching method. The composite scaffolds were made from seven different biosilica extract and PCL. All of the scaffolds were tested for the cell morphology, Fourier-transform infrared spectroscopy (FTIR), immunocytochemistry, and cytotoxicity.RESULTS: Composite scaffolds of 50% M. sarasinorum and X. testudinaria increased the cell viability and supported the cell growth within 14 days, whereas the osteogenic differentiation can be seen by the presence of collagen type 1 in day 12 based on immunocytochemistry result.CONCLUSION: The biosilica scaffolds from PCL+50% M. sarasinorum and PCL+50% X. testudinaria were promising 3D scaffolds for potential application in bone tissue engineering. In conclusion, this study shows evidence for the osteogenic differentiation of hWJ-MSC, which might be developed for bone tissue engineering.KEYWORDS: sponge, biosilica, scaffold, osteogenesis, stem cell

The Indonesian archipelago is a ‘hotspot’ for invertebrate biodiversity (‘Coral Triangle’). In this area of ‘peak’ biodiversity, the origins of this high species diversity have often been debated. Xestospongia testudinaria is one of the sponge species that dominates coral reef sponge communities in this region. The role of the so-called ‘giant barrel sponge’ for the reef ecosystem has been studied repeatedly, as have its various bioactive compounds. However, the genetic variation of this iconic sponge in the region remains unknown. We investigate over 200 barrel sponge samples from Indonesia, and neighbouring as well as more distant localities (Saudi Arabia, Tanzania, Thailand, Taiwan, Java, Sulawesi and the Great Barrier Reef, Australia) using the mitochondrial cytochrome oxidase subunit 1. We compare our results with those from the studies on the congeneric barrel sponges Xestospongia muta from the Caribbean, and Xestospongia bergquistia from the Indo-Pacific, and observe a high degree of overlapping haplotypes between the three barrel sponge species, likely indicating the presence of ancestral polymorphisms. We discuss the implications of these findings to better interpret the phylogeography of barrel sponge taxa in the Indo-Pacific.

The species diversity and distribution of demosponges dwelling in the coral reefs, at Had Khanom—Mo Ko Thale Tai National Park on the southern coast of the Gulf of Thailand, was investigated, with field surveys undertaken at 12 sites in November 2006 using SCUBA diving and random observation. Forty-five species of demosponges from 10 orders, 24 families and 34 genera were recorded. The most abundant and common sponges in this area are: Oceanapia sagittaria; Neopetrosia sp. blue; Xestospongia testudinaria; and Haliclona (Gellius) cymaeformis. Most species are common representatives of the Indo-Pacific fauna found throughout the Gulf of Thailand.

Streszczenie:

Sponge makin banyak menarik perhatian para ilmuwan di seluruh dunia bukan karena potensi bioekologisnya saja tetapi juga karena potensi kosmetik dan biomedis dari molekul-molekul bioaktif maupun biomaterial sponge. Sangat disayangkan, pengetahuan tentang diversitas sponge di wilayah dengan biodiversitas tertinggi di dunia seperti Sulawesi Utara dan Wallacea pun masih sangat miskin dengan sebagian informasi diversitas sponge wilayah-wilayah ini tersebar dalam literatur-literatur ilmiah yang sudah usang dan terfragmentasi. Studi ini bertujuan untuk meningkatkan pengetahuan taksonomi dasar sponge di Sulawesi Utara khusunya di perairan Tahuna Kepulauan Sangihe sekaligus memberikan gambaran umum tentang distribusi dan potensi farmakologis dari sponges yang umum ditemukan di perairan Tahuna. Menggunakan metode acid digestion dan kombinasi mikroskop cahaya dan Corel Draw, kami mengidentifikasi tujuh spesies umum di terumbu karang Tahuna yaitu Agelas nakamurai, Clathria reindwardtii, Ircinia strobilina, Melophus sarasinorum, Speciospohongia vagabunda dan Xestospongia testudinaria. Selain menyentil tentang molekul-molekul bioaktif, tulisan ini juga secara singkat membahas tentang penyebaran ketujuh jenis sponge itu terutama di kawasan Asia Tenggara, selatan Jepang dan Australia untuk memperlihatkan sebaran sekaligus potensi kandungan bioaktif dan biomaterial dari sumberdaya laut amat berharga tetapi terabaikan dalam berbagai program monitoring dan konservasi terumbu karang di Indonesia ini. Sementara M. sarasinorum, S. vagabunda C. reinwardti, dan X. testudinaria terlihat memiliki distribusi sangat luas di wilayah Indo Pasifik, Agelas nakamurai dan I. strobilina sejauh ini baru dilaporkan di perairan Okinawa, Asia Tenggara dan Wallacea meskipun spesies serupa dari kedua genus itu terdistribusi hampir di seluruh Australia. Artikel ini mewakili laporan pertama tentang diversitas, kandungan molekul dan sebaran geografis sponge umum dari perairan Kabupaten Sangihe. Sponges have attracted considerable attention not only because of their bioecological but also due to cosmetical and medical potentials of bioactive compounds and biomaterials from sponges. Unfortunately, the basic knowledge of this impressive marine invertebrate, even in rich biodiversity region such as North Sulawesi, remains poorly known with such information scattered in old and fragmented literatures. This research aimed to increase the basic taxonomic knowledge and medical potential of seven sponges in Tahuna’s coral reefs Sangihe Islands as an step to encourage monitoring and concervation of this key species in coral reef in Sangihe Islands. Using acid digestion method and combination of light microscope and Corel Draw, we identified seven common species in Tahuna’s coral reefs namely reinwardti, Ircinia strobilina, Melophus sarasinorum, Speciospongia vagabunda and Xestospongia testudinaria. In addition to providing a quick review on the distribution of these species especially in South East Asia, southern Japan and Australia, the authors also touched on bioactive compounds produced by these animal isolated by one of the authors either from Sangihe Island’s sponges or sponges from other locations to give an overview of the bioactive potential and geographical distributions of the impressive but ignored marine resource in coral reefs’ monitoring and conservation programs in Indonesia. While sepecies such as M. sarasinorum, S. vagabunda C. reinwardti, and X. testudinaria seem to well distributed in Indopasific, A. nakamurai and I. strobilina are distributed only in south Japan and Wallacea regions although the sibling species of the two sponges have been well reported throughout Australia. This article represents the first report on biodiversity, distribution and bioactive molecules of sponges from Sangihe Islands.

BACKGROUND: The coral reef on Mandeh Island, West Sumatra, Indonesia, consists of an abundant source of sponge and soft coral. Secondary metabolites of marine-derived fungi isolated from the sponge and soft coral possess numerous biological activities. AIM: This study collected, identified, and screened marine-derived fungi isolated from marine invertebrates for antibacterial and cytotoxic bioactivities. MATERIALS AND METHODS: The marine invertebrates used are sponges; Xestospongia testudinaria and Placortis communis) and soft corals (Sarcophyton elegan and Subergorgia suberosa). The EtOAc extracts were analyzed for antimicrobial and cytotoxic activities using the diffusion agar method and brine shrimps lethality test. RESULTS: After cultivating on rice medium, the EtOAc extracts of 22 isolated fungi showed potent antimicrobial activity with an inhibitory zone of 15.9 mm against Staphylococcus aureus (XT2 extract), and Pseudomonas aeruginosa of 26.7 mm (XT6 extract), and Candida albicans of 29 mm (SE5 extract). XT6 extract showed the potential cytotoxic activity with an LC50 value of 100 μg/ml. CONCLUSION: The ability of the marine-derived fungi to produce bioactive compounds is promising potential as a source of antimicrobial and cytotoxic compounds.

BACKGROUND: Diabetes mellitus is a metabolic condition characterized by high blood glucose levels due to insufficient insulin secretion or activity. Diabetes treatment may include inhibiting carbohydrate breakdown enzymes like α-glucosidase. Chemical compounds of the marine-derived fungus have the potential to inhibit α-glucosidase and, thus, could be used in therapy. Marine sponge-derived fungus lives in a colony on the tissues of living things. In the marine sponge Xestospongia testudinaria DD-01, there is a colony of the fungus Penicillium citrinum Xt6. P. citrinum Xt6 has been reported to reduce blood glucose levels in alloxan-induced diabetic mice. AIM: This study aimed to investigate the inhibitory activity of α-glucosidase by the extracts and fractions of marine-derived fungus P. citrinum Xt6. MATERIALS AND METHODS: The study was carried out in vitro using p-nitrophenyl-α-D-glucopyranoside (PNPG) substrate and α-glucosidase enzyme from Saccharomyces cerevisiae. ELISA was used to measuring the enzyme’s inhibition activity at the wavelength of 405 nm. Acarbose was used as the standard drug, which inhibits the activity of α-glucosidase. RESULTS: Inhibitory concentration (IC50) value of ethyl acetate extract was 37.39 μg/mL, methanol fraction was 60.01 μg/mL, n-hexane fraction was 75.45 μg/mL, and acarbose was 124.39 g/mL. CONCLUSION: It can be concluded that the extract and fraction of marine-derived fungus P. citrinum inhibit α-glucosidase activity. P. citrinum could be developed into an antidiabetic agent.

Abstract In the present study, we used Illumina sequencing to explore the prokaryote communities of 17 demosponge species and how they compare with bacterial mat, sediment and seawater samples (all sampled from coral reef habitat in Taiwan and Thailand). The studied sponge species formed three clusters. OTU richness and evenness were by far highest in the sediment and bacterial mat biotopes. There were pronounced differences in OTU richness and evenness among clusters and also considerable variation among certain host species within clusters. Additionally, the relative abundance of some prokaryotic taxa also differed among clusters with Poribacteria, for example, being recorded in all sponge species, but with very low relative abundances in species of two of the three clusters. This sponge-associated phylum was, however, recorded at relatively high mean abundance in bacterial mat samples, which also housed relatively high abundances of actinobacterial and Chloroflexi members. Our results support the HMA status of the species Aaptos lobata, Hyrtios erectus, Pseudoceratina purpurea and Xestospongia testudinaria, which clustered together and LMA status of the species Acanthella cavernosa, Echinodictyum asperum, Jaspis splendens, Ptilocaulis spiculifer, Stylissa carteri and Suberites diversicolor, which also clustered together. Other species (Agelas cavernosa, Agelas nemoechinata, Acanthostylotella cornuta, Paratetilla sp., Hymeniacidon sp. and Haliclona cymaeformis) deviated somewhat from the typical HMA/LMA dichotomy and formed a strongly supported cluster.
