Abstract

Morphology and molecular characterization of microalgae isolated from Wakatobi Marine National Park was conducted. An understanding of the characteristics of morphology, molecular, as well as metabolites profile of the microalgae species is potentially useful for its future application. The primary aim of this study was to isolate, identify and characterize the microalgae strain isolated from Wakatobi Marine National Park labeled as LIPI13-WKT066 with the emphasis on the evaluation of amino acid content as a basis for its health application. Morphological observation under the microscope and molecular identification suggested that the microalgae strain of LIPI13-WKT066 belong to the strain under species of Chlorella volutis. Metabolite characterization of the microalgae strain showed that the content of protein (11.9%), lipid (12.4%) and carbohydrate (4.7%) was in the regular range. Further analysis of its amino acid content revealed the potency of the microalgae strain to be used as antihypertensive agent.

Abstract

Three strains of fast-growing microalgae were investigated in this study for their potential of lipid production and its possible use in health application. Lipid content, lipid productivity, and fatty acids profile of the 3 mi-croalgae strains were also analyzed. The strain of LBB13-2-AL045 and LBB13-2-AL048 possessed highest lipid content (49.08 ± 0.25%) and lipid productivity (40.27 ± 1.91 mg.L-1.day-1), respectively, among the other tested strains. The fatty acids profile from the 3 strains exhibited its possible use in health application. The two strains of LBB13-2-AL046 and LBB13-2-AL048 possessed high valuable fatty acids of polyunsaturated fatty ac-ids (PUFA) omega-3 and omega-6, whereas LBB13-2- AL045 possessed balance ratio of saturated fatty acid (SFA) : monounsaturated fatty acid (MUFA) : PUFA (1 : 1.3 : 1) as is recommended by American Heart As-sociation (AHA) (1 : 1.4 : 0.8). The high content of omega-3 and omega-6 fatty acids indicated that the algal lipids of two strains (LBB13-2-AL046 and LBB13-2-AL048) were potential to be applied in cardiovascular health. The balance ratio of SFA : MUFA: PUFA as is recommended by AHA indicated that the algal oil of LBB13-2-AL045 strain was recommended in order to generate the best LDL/HDL ratio.

Abstract

Limbah cair industri kelapa sawit (palm oil mill effluent atau POME) di Indonesia menghasilkan volume yang tinggi dan berpotensi mencemari lingkungan. Mikroalga dapat dimanfaatkan untuk mengurangi limbah sekaligus menghasilkan produk biomassa yang bernilai tambah. Penelitian ini bertujuan menentukan konsentrasi optimum POME bagi pertumbuhan mikroalga Galdieria sulphuraria 009, mengevaluasi produksi fikosianin, serta menilai aktivitas antioksidannya. Penelitian ini diawali dengan penapisan awal menggunakan 5–50% POME untuk mengidentifikasi kondisi pertumbuhan mikroalga yang optimum; budi daya dalam bioreaktor dengan variasi konsentrasi (2,5; 5,0; dan 7,5%) untuk mengevaluasi kinerja pertumbuhan; dan analisis aktivitas antioksidan serta kandungan pigmen dalam biomassa. Penapisan awal menunjukkan bahwa POME 5% merupakan konsentrasi optimal, sedangkan konsentrasi lebih tinggi menghambat pertumbuhan akibat berkurangnya penetrasi cahaya. Pada budidaya lanjutan, mikroalga dalam POME 2,5% menunjukkan hasil sebanding dengan kontrol (Allen pH 2), sedangkan konsentrasi lebih tinggi menghambat pertumbuhan akibat penaungan dan toksisitas amonia. Produksi fikosianin per volume kultur tertinggi diamati pada mikroalga yang dibudidayakan dalam POME 2,5%, dengan hasil yang sebanding dengan media kontrol. Uji aktivitas antioksidan mengonfirmasi bahwa semua ekstrak fikosianin memiliki aktivitas antioksidan yang signifikan, dengan aktivitas tertinggi pada POME 7,5%. Kandungan karotenoid dan klorofil a dievaluasi dalam biomassa segar dan residu setelah ekstraksi. Karotenoid lebih melimpah dalam biomassa segar, sedangkan klorofil a lebih tinggi dalam residu biomassa. Penelitian ini menunjukkan bahwa G. sulphuraria 009 berpotensi sebagai sumber fikosianin yang layak dalam budidaya berbasis POME, serta memberikan wawasan mengenai pemanfaatan limbah industri dan pengembangan produk bioteknologi berkelanjutan.
