Abstract

Indonesia has a great sea cucumber resource which is useful as functional food. Even though much information about the biopotency of sea cucumbers have been published, however, studies on nutrition value of Indonesian sea cucumbers are still beneficial due to the great diversity and uniqueness of each species. The present work was  intended to obtain information about chemical composition and fatty acid profile of 4 (four) types of sea cucumbers which are frequently found in Halmahera water, North Maluku (Molucca),  one  of  sea  cucumbers  producing area  in Indonesia. The samples coded as  H-03, H-04, H-05 and H-10, were identified as Bohadschia  argus, Holothuria  fuscogilva, Thelenota  ananas, and Actinophyga lecanora. All sea cucumbers showed high protein content, more than 60% (drybase/db), except for T. ananas which had the lowest protein content (48.26% db). As for fats, T. ananas showed the highest amount (2.35%db) with dominated saturated fatty acids (SFA). On the other side, A. lecanora showed higher value of PUFA compared to SFA and MUFA.  Palmitic acid (C16:0) was the most abundant SFA in the most samples with the amount of 0.49–4.9 mg/g sample. Among PUFA, eicosapentaenoic acid/EPA (C20:5n3) was detected, and eicosatrienoic acid (C20:3n6) was relatively higher than the others. The ratio of w6/w3 fatty acid was 1.2–3.2 showing that total w6 fatty acid was higher than total w3 fatty acid. However, this value is safe enough to protect against chronic and degenerative diseases.

Abstract

Akhir-akhir ini bioprospeksi mikroorganisme laut semakin populer dan banyak  diminati karena potensinya yang menjanjikan sebagai sumber komponen bioaktif baru. Identifikasi mikroorganisme merupakan salah satu tahapan yang penting dalam bioprospeksi. Perkembangan identifikasi mikroba diawali dengan identifikasi melalui ciri-ciri morfologi, fisiologi, dan metabolisme. Namun adanya kekurangan-kekurangan metode ini yaitu berupa ketidakakuratan dan waktu identifikasi yang lama menjadikan metode secara molekuler lebih berkembang. Pada bakteri, 16S ribosom deoxyribonucleic acid (rDNA) mempunyai daerah sekuen yang konservatif sehingga dapat digunakan untuk menduga hubungan kekerabatan secara alami  antar  spesies. Sedangkan pada kapang digunakan 18S rDNA dan daerah internal transcribed spacer (ITS) untuk identifikasinya. Tahapan identifikasi dengan metode molekuler meliputi ekstraksi deoxyribonucleic acid (DNA), amplifikasi DNA, sekuensing, analisis hasil sekuen, dan pembuatan pohon filogenetik. Balai Besar Riset Pengolahan Produk dan Bioteknologi Kelautan dan Perikanan (BBRP2B-KP) memiliki  koleksi mikroba potensial penghasil enzim kitosanase, kitinase, dan protease dari berbagai sampel dari lingkungan laut. Berdasarkan pohon filogenetik  beberapa isolat koleksi memiliki kemiripan 87–96% dengan Staphylococcus caprae, Stenotrophomonas maltophilia, Acinetobacter sp., Bacillus licheniformis, Geobacillus stearothermophilus.

Abstract

Golden sea cucumber or locally known as “teripang emas” is one of Indonesia’s most popular sea cucumber and widely processed as functional food or supplement due to its bioactivities. The sea cucumber is often misidentified due to its morphological similarities with other Stichopus spp. This study aimed to identify the golden sea cucumber obtained from West Nusa Tenggara, Indonesia, by a molecular method and study the antioxidant activities of its collagen hydrolysates. The hydrolysates were produced by hydrolyzing acid collagen extract using neutrase for 30, 60, 120, 180, and 240 mins. The products were then analyzed for their degree of hydrolysis, peptide content, molecular weight distribution and radical scavenging activity by the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) method. Results showed that hydrolysis for 180 mins was optimal in producing the highest peptide content, 12.79 ± 0.44 mg/mL, with a degree of hydrolysis (DH) of 55.2 ± 1.50%. However, the highest antioxidant activity (IC50 of 5.25 ± 0.15 mg/mL) was demonstrated after 60 mins hydrolysis with molecular weight (MW) ranged from less than 14.4 kDa to approximately 25 kDa. The hydrolysate might be categorized as a weak to moderate antioxidant. Based on the molecular identification, the golden sea cucumber had 99% similarities with Stichopus horrens and S. monotuberculatus.
