Spirulina sp. LEB18 when raised in aquatic wastewater environment is supplemented with 25% Zarrouk environmental nutrients for effective wastewater treatment and effective heavy metal absorption.With a dense system of rivers and canals, it can be said that fisheries have been considered as one of the strengths of the Vietnamese economy, accounting for a large proportion in the industrial structure. Demand for aquatic products at home and abroad increases while natural resources are gradually depleted, that's why the aquaculture industry was born to make up for that shortfall as well as meet domestic and foreign demand. . Along with the rapid development of the aquaculture industry in recent years are inevitable negative things. One of them is the problem of wastewater treatment of ponds or aquaculture facilities. Wastewater includes wastewater in the process of farming (wastewater from shrimp and fish farming, ...) and wastewater during processing, containing high levels of BOD, COD, Nitrogen and pathogenic microorganisms from feces. dead fish carcasses, residual chemicals, food mixed in the water environment. Therefore, the solution to treat wastewater safely, effectively and cost-effectively is receiving a lot of attention.Also read: Mexico-based Startup Turns Wastewater Into Fish FeedSpirulina platensis is a green filamentous, photoautotrophic microalgae, belonging to the family Cyanobacteria. Metabolism in microalgae is highly dependent on the composition of the medium and the culture conditions. With chemical properties such as high protein content (~70%), lipid (3 - 9%), carbohydrates (15 - 30%), carotene (superior to carrots) and vitamins (including B1, B2 and B12) allows them to be widely used in human and animal pharmaceutical, cosmetic and food technology.Spirulina platensis is a nutritional supplement for all ages who are in need such as the elderly, athletes, pregnant women, children. Enhance resistance, antioxidant, anti-inflammatory, nutritional balance, hormone regulation, skin care, beauty, stress relief, support recovery for chronic patients, after injury, after surgery, chemistry long-term treatment, radiation therapy, antibiotics Suitable for the diet of people with obesity, diabetes, high blood pressure, etc. However, there are still quite a few studies done to evaluate wastewater quality based on the synthesis of molecules. biology of microalgae. Faced with this problem, the research conducted aims to combine the cultivation of Spirulina biomass in parallel with wastewater treatment in aquaculture, while promoting the increase of macronutrients. Spirulina   Spirulina sp. LEB18Spirulina Spirulina sp. LEB18 was grown in a 1L photobioreactor (Photobioreactor) to determine the best conditions through growth indicators. The experiment was repeated twice including 1 control treatment: 100% Zarrouk medium and 4 treatments: 100% wastewater and the addition of 75, 50, 25, 0% Zarrouk medium, respectively, within 7 days. , temperature 30 o C, 12 h am/dark, using aeration, the amount of water evaporated from the culture medium was added daily. The results showed that the highest growth parameters in the 1L photobioreactor system were continued to be used in the pilot-scale bioreactor of 5L for 10 days.Also read: ‘Water-forecasting’ and Fish Farms Fed on WasteAquaculture wastewater is collected before and after culture to check chemical composition, growth index, biomass composition, mineral composition, trace elements, determination of chlorophyll a. , b and total carotenoids and fatty acids.The obtained results showed that all growth indices of Spirulina sp. LEB18 when reared in aquatic wastewater with 25% Zarrouk environmental nutrients added to it showed higher efficiency than the control treatment (100% Zarrouk medium). Besides, the ability to reduce a large amount of phosphate (99.97%); COD (89.34%) and nitrate (81.10%) due to the common mechanism of microalgae using NO 3 through nitrate and nitrite reducing enzymes during cell proliferation. It is also one of the effective solutions when currently in the industrial scale, nitrogen is often added to the culture medium of spirulina S. platensis from nitrate salts (NO 3 ), however, these sources are often expensive. high. At the same time, they also have the ability to well absorb toxic heavy metals such as lead (Pb), mercury (Hg), cadmium (Cd) and arsenic (As) from aquaculture wastewater. Metal removal occurs due to the presence of carboxylate groups, which are mainly responsible for metal absorption on the surface of microalgae cells. Mineral composition has also been improved such as aluminum (Al), iron (Fe), calcium (Ca) and magnesium (Mg).  Also read: Intestinal Bacteriome of Pacific White Shrimp in Biofloc, Clear Water SystemsTherefore, the addition of 25% Zarrouk in aquaculture wastewater allows to obtain high yields in the rearing of biomass, carbohydrates, lipids and carotene with low production cost, which is an eco-friendly natural raw material. The field is highly feasible, which is significant in both science and practice.Source: Tepbac.com ...

Sektor kelautan dan perikanan bisa menjadi pengungkit ekonomi nasional di tengah pandemi Covid-19. Optimisme tersebut diungkapkan Direktur Jenderal Penguatan Daya Saing Produk Kelautan dan Perikanan (PDSPKP), Artati Widiarti saat membuka webinar Tropical Seaweed Innovation Network (TSIN) series bertajuk "Mengenal Lebih Dekat Keanekaragaman Rumput Laut di Indonesia", Selasa (15/6/2021).Menurutnya, rumput laut merupakan salah satu sumber daya hayati yang sangat melimpah di perairan Indonesia. Bahkan jumlahnya mencapai 8,6% dari total biota di laut. Luas wilayah habitat rumput laut di Indonesia mencapai 1,2 juta hektare atau terbesar di dunia."Ini baru dari komoditas rumput laut, potensi sektor kelautan dan perikanan sudah sedemikan luar biasa," kata Artati.Baca juga: Cara Memilih Bibit Rumput Laut Berkualitas BaikTak hanya itu, mengutip paparan Tri Handayani, peneliti dari Pusat Penelitian Oseanografi LIPI yang menyebutkan bahwa saat ini Indonesia memiliki kekayaan makroalga  sebanyak 89 suku (familia), 268 marga (genus)  dan 911 jenis (species).Dari sekian jenis, rumput laut dari kelas alga merah (Rhodophyta) menempati urutan terbanyak dari jumlah jenis yang tumbuh di perairan laut Indonesia yaitu sekitar 564  jenis, disusul alga hijau (Chlorophyta) sekitar 201 jenis dan alga coklat (Ochrophyta) sekitar 146."Keberlimpahan sumber daya hayati rumput laut ini tentunya merupakan anugerah bagi bangsa Indonesia yang dapat didayagunakan sebagai penggerak ekonomi nasional, penyedia lapangan kerja, penghasil devisa serta menjadi sumber pangan dan gizi nasional," urai Artati.Dalam kesempatan ini, Artati menegaskan riset dan inovasi adalah kunci peningkatan daya saing di pasar global. Karenanya, keberadaan TSIN yang beranggotakan para peneliti, pakar dan praktisi rumput laut di Indonesia, bisa menjadi kekuatan guna menjembatani antara inovasi dan industri, agar komersialisasi hasil riset dan inovasi rumput laut dan dapat terwujud.Baca juga: Mengenal Alga Merah Dan Manfaatnya Bagi Manusia"Untuk memperkuat posisi dan peran TSIN dalam perumput lautan Indonesia perlu diupayakan agar TSIN menjadi sebuah lembaga yang akan mengawal percepatan industrialisasi dan peningkatan daya saing rumput laut Indonesia," tegasnya.Melalui sinergitas riset, inovasi dan penerapan di lapangan, Artati meyakini Indonesia bisa menjadi pemain utama dalam industri rumput laut dunia. Terlebih proyeksi permintaan rumput laut negara-negara Asia Pasifik sebagai pasar terbesar, mencapai USD23,04 miliar di tahun 2027.Lonjakan permintaan terjadi karena meningkatnya permintaan untuk industri pangan, pakan, obat-obatan dan kosmetik."Pasar menurut Fortune Business Insights akan terus tumbuh dengan meningkatnya permintaan dan produksi dari negara-negara seperti Tiongkok, Korea Selatan, India dan Jepang, termasuk Indonesia untuk bahan pangan, kosmetik, farmasi, bahan perekat dan gel," jelas Artati.Baca juga: ARLI: Bali Bisa Bangkitkan Kembali Rumput LautSenada, Direktur Pemasaran Ditjen PDSPKP, Machmud menyebutkan bahwa pemanfaatan rumput laut untuk konsumsi manusia menyumbang lebih dari 77% dari keseluruhan pangsa pasar global. Kebutuhan ini diproyeksikan meningkat di masa mendatang karena perubahan lifestyle kebiasaan makan yang sehat, dan meningkatnya populasi penduduk.Khusus untuk pasar Amerika Serikat, Machmud menyebut nilai industri rumput laut sebesar USD311,4 juta pada tahun 2019. Jumlah ini diperkirakan berkembang pesat dengan meningkatnya pemanfaatan untuk industri farmasi.  Selain itu, kebutuhan rumput laut merah pada 2020 – 2027 diprediksi akan tumbuh 9,2% dengan  produk utama semi-olahan dan olahan, khususnya karaginan."Permintaan pasar rumput laut di AS didominasi oleh jenis merah, diikuti oleh cokelat dan hijau," tutup Machmud.
