“…The optimal condition was determined to be 34.8 MPa, 48 • C, and 8% co-solvent with an optimal yield of 133.9 mg GAE/g biomass. These results are better than those reported in other studies using I. galbana as natural biomass rich in bioactive compounds through conventional methods of extraction [33,34]. For example, Widowati et al [33] and Foo et al [35] reported yields from I. galbana clone Tahiti, and I. galbana to be nearly 17.79 mg GAE/g and 12.24 mg GAE/g, respectively.…”

A microalga, Isochrysis galbana, was chosen in this study for its potent natural antioxidant composition. A broad bioactive compounds spectrum such as carotenoids, fatty acid polyunsaturated (PUFA), and antioxidant activity are described with numerous functional properties. However, most of the optimization of extraction use toxic solvents or consume a lot of it becoming an environmental concern. In this research, a Box-Behnken design with desirability function was used to prospect the bioactive composition by supercritical fluid extraction (SFE) after performing the kinetics curve to obtain the optimal extraction time minimizing operational costs in the process. The parameters studied were: pressure (20–40 MPa), temperature (40–60 °C), and co-solvent (0–8% ethanol) with a CO2 flow rate of 7.2 g/min for 120 min. The response variables evaluated in I. galbana were extraction yield, carotenoids content and recovery, total phenols, antioxidant activity (TEAC method, trolox equivalents antioxidant capacity method), and fatty acid profile and content. In general, improvement in all variables was observed using an increase in ethanol concentration used as a co-solvent (8% v/v ethanol) high pressure (40 MPa), and moderately high temperature (50 °C). The fatty acids profile was rich in polyunsaturated fatty acid (PUFA) primarily linoleic acid (C18:2) and linolenic acid (C18:3). Therefore, I. galbana extracts obtained by supercritical fluid extraction showed relevant functional ingredients for use in food and nutraceutical industries.

“…Alkenones, therefore, represent a potentially abundant and renewable resource available from common algae, with a history of large-scale production [9]. Isochrysis species have been noted for their high lipid content [10], and potential application in cosmetic and personal care products [11][12][13]. The high-melting lipids, being naturally sourced (i.e., green and non-GMO) and sustainable, may be of interest to the cosmetic and personal care industry.…”

Abstract:The move toward green, sustainable, natural products has been growing in the cosmetic and personal care industry. Ingredients derived from marine organisms and algae are present in many cosmetic products. In this study, a new green ingredient, a wax (i.e., long-chain alkenones) derived from Isochyrsis sp., was evaluated as an alternative for cosmetic waxes. First, the melting point was determined (71.1-77.4 • C), then the alkenones' thickening capability in five emollients was evaluated and compared to microcrystalline wax and ozokerite. Alkenones were compatible with three emollients and thickened the emollients similarly to the other waxes. Then, lipsticks and lip balms were formulated with and without alkenones. All products remained stable at room temperature for 10 weeks. Lipstick formulated with alkenones was the most resistant to high temperature. Finally, alkenones were compared to three cosmetic thickening waxes in creams. Viscosity, rheology, and stability of the creams were evaluated. All creams had a gel-like behavior. Both viscosity and storage modulus increased in the same order: cream with alkenones < cetyl alcohol < stearic acid < glyceryl monostearate. Overall, alkenones' performance was comparable to the other three waxes. Alkenones can thus offer a potential green choice as a new cosmetic structuring agent.

Chlorella vulgaris termasuk salah satu jenis mikroalga hijau bersel tunggal (unicellular) yang diameter selnya berkisar antara 2-8 mikron. Pigmen pada Chlorella vulgaris selain berfungsi sebagai aktivitas antioksidan tetapi juga memiliki efek perlindungan terhadap degenerasi retina dan memperkuat sistem kekebalan tubuh. Penelitian ini bertujuan untuk mengetahui kandungan Betakaroten pada Mikroalga Chlorella vulgaris yang dikultur dengan perlakuan sumber cahaya dan kepadatan awal inokulum yang berbeda. Metode penelitian yang digunakan adalah metode eksperimental, sedangkan rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap Faktorial terdiri atas 6 perlakuan dan 3 kali ulangan. Perlakuannya adalah sumber cahaya neon (32 watt) yang ditambahkan dengan LED Merah, LED Hijau dan LED Biru masing-masing 16 watt dengan KAI C.vulgaris yang dikultivasi yaitu 10x104 sel/ml dan 100x104 sel/ml. Hasil penelitian menunjukkan Kandungan Pigmen β-karoten tertinggi yaitu 721,572 mg/l pada LED biru dengan Kepadatan Awal Inokulum (KAI) 100x104 sel/ml.
