The main challenges to overcome in biodiesel production from microalgae are lower oil yield, as compared to those derived from plant and animal biomass, and expensive culture media. This work was aimed to compare the effectivity of three extraction methods differed in solvent used, e.g. n-hexane (N-hex), ethanol (Eth), and mixture of chloroform-methanol-water (CMW), to extract crude lipid and biodiesel from dry biomass of Chlamydomonas sp. ICBB 9113. This microalgae was cultivated in a cheap culture media using N and P soil fertilizers as nutrient sources. The results showed that, by using N-hex, Eth, and CMW methods, it could be extracted, respectively, 0.06%, 4.51%, and 20.45% crude lipid, and 384.2, 1333.8, and 2430.6 mg/100g biodiesel. The fatty acid profile of the studied microalgae biomass was: C8:0 (0.11%), C10:0 (0.09%), C14:0 (7.70%), 16:0 (1.39%), C18:0 (0.85%), C14:1 (5.12%), C16:1 (7.09%), C18:1 (8.28%), C18:2 (12.80%), and C18:3 (42.57%). Fatty acid characterization showed that Chlamydomonas sp. ICBB 9113 was dominated by C18: 3 and C16:0. Therefore, these microlagae were suitable to be used as raw material for biodiesel production to substitute the conventional fuel.

A green alga, Chlorella vulgaris was grown semi-continuosly at various harvesting periods, and the lipid content and its associated antioxidant activity was examined. The harvesting periods were 9, 18, and 27 days, while the algal culture was placed in 10 L glass bottles provided with aeration for gas exchange and mixing. Light was obtained from 440 watt cool fluorescent lamps placed at one side of the culture. Room temperature was 26-32C. Algal lipid extraction was done based on liquid phase separation of methanol :chloroform:water and the antioxidant activity was examined by means of oxidation inhibitory in ethanol emulsified limnoleic acid. In addition, a TLC analysis was performed to identify the antioxidant compouns soluble in the lipid. The results showed that harvesting per iod had a significant influence on the algal lipid content, which were 11.94, 12.96, and 16.51% of the dry weight in the culture with harvesting periods of 9, 18, and 27 days, respectively. No remarkable effect of the harvesting period on the antioxidant activity, which were observed to inhibit oxidation of linoleic acid up to 67-71%. There were five compounds found can be associated with the algal antioxidant activity, which were pheophorbide -a, chlorophyll-b,chlorophyll-a, phaeophytin-a, -carotene, and an unidentified one.

Salmon imports continue to rise, while there were indications in some waters of the salmon's origin country that is a potential danger of heavy metals contamination. This phenomenon raises awareness regarding the food safety of salmon consumption, therefore a risk assessment is crucial to be conducted. The purposes of this study were to determine the content of Hg, Pb, and Cd in salmon meat and to assess the risk of heavy metals in salmon consumption in Jabodetabek area. Salmon fish, 132 in total was randomly taken from Tanjung Priok Port, the heavy metal analysis used the Flameless Inductively Coupled Plasma Mass Spectrometry instrument, risk assessment based on the United States Environmental Protection Agency method and risk ranger based on Ross and Sumner, supported by systematic literature review and questionnaires. The heavy metals Hg, Pb, and Cd in salmon were detected at 0.0646±0.0056, 0.0505±0.0446, and 0.0119±0.0006 ppm, respectively, indicating that there were still below the thresholds set by Food and Drug Supervisory Agency of the Republic of Indonesia (0.5;0.2;and 0.1 ppm). The results of the semi-quantitative risk assessment for Hg, Pb, and Cd were 0.0567, 0.0013, and 0.0010 (less than 1) implying that salmon consumption have no a potential risk of hazard. However heavy metals are accumulated in human body, hence, the diet consumption analysis needed to be performed. The risk ranger showed that the estimated risk ranking of heavy metals was in the medium category. Based on the results, it can be concluded that imported and consumed salmon by Jabodetabek residents was still relatively safe.

Previous research showed that Stichopus hermannii and Spirulina platensis had an antioxidant activity. It is indicated by the reduced malondialdehyde (MDA) level in the liver of the diabetic rats. However, the STZ administration did not significantly increase MDA concentration of diabetic rats' blood serum for 14 days. This research aimed to determine in vitro and in vivo MDA inhibition of S. hermanii and S. platensis. The in vitro antioxidant activity test was conducted using the MDA-TBA method, and a positive control used α-tocopherol. For in vivo experiment, diabetic rats (DM) were induced by streptozotocin for 21 days. Twenty-five rats which were divided into five groups: normal rat group (NA), diabetic rat group (DA), diabetic rat group + glibenclamide (DG), diabetic rats + Stichopus hermanii (SH), and diabetic rats + Spirulina platensis (SP). The in vitro results showed that the antioxidant activity of 25 ppm Spirulina platensis had the same MDA inhibitory activity as 200 ppm α-tocopherol, but 200 ppm Stichopus hermanii had lower inhibition than 200 ppm α-tocopherol. The in vivo result showed that Stichopus hermanii treatment was more effective in suppressing blood serum MDA concentration, but Spirulina platensis was more effective in suppressing liver MDA concentration.

Omega-3 is very important for preventing the effects of decreased intelligence. The limitation of omega-3 is that it is highly susceptible to oxidation, which necessitates the inclusion of additional substances with antioxidant properties. Spirulina platensis can be used to prevent the oxidation of omega-3 in the form of dry dosages. The objective of this study was to identify the optimal formulation for incorporating microcapsules of tuna eye oil and S. Platensis in the production of tablets by considering physicochemical parameters, peroxide value, and water activity. The present study encompasses three distinct phases: extraction and encapsulation of tuna eye oil, cultivation of S. platensis, and formulation of tablets using the compression method. Treatments involving the tablet formula were classified into four distinct categories: F1 (containing 300 mg of tuna eye oil microcapsules and 140 mg of vitamin C), F2 (comprising 280 mg of tuna eye oil microcapsules and 160 mg of Spirulina culture), F3 ( 300 mg of tuna eye oil microcapsules and 140 mg of Spirulina culture), and F4 (containing 300 mg of tuna eye oil microcapsules and 140 mg of commercial Spirulina). The examination demonstrated that the eye oil derived from tuna satisfied the criteria for fish oil quality, with an acid value of 0.26±0.01 mg KOH/g, a peroxide value of 4.07±0.25 meq/kg, an anisidine value of 8.21±0.15 meq/kg, and a total oxidation value of 16.35±0.18 meq/kg, as well as a microencapsulation efficiency of 91.14%. The cultivation method employed in this study also ensured that the resulting Spirulina met the acceptable quality standards. The dry Spirulina had a water content of 9.02±0.07%, an ash content of 6.24±0.06%, a protein content of 57.55±0.21%, a fat content of 2.07±0.02%, and a carbohydrate content of 25.12±0.16%. The F3 tablet formulation was the most effective treatment, with physical properties that met the standards for tablet quality. It has a firmness value of 0.55%, disintegration time of less than 12 min, and fat content of 13.57%. The F3 formula demonstrated greater stability with respect to peroxide value and water activity during the storage period than the other formulas.

Bekasam is a fermented fish product that tastes sour. Bekasams commonly employ freshwater fish, carbohydrate sources, and salt, which are left to ferment spontaneously for a period of 5-10 days. The quality of the bekasam produced was not uniform. This study aimed to investigate the microbiological and chemical properties of bekasam during the fermentation process using a single and mixed starter, and to identify the optimal treatment for the selected starter in terms of its chemical composition and sodium chloride content. The addition of 7.5% (weight-to-weight) salt and 25% (weight-to-weight) dry rice to the prepared Nile tilapia fish was followed by sterilization at 100 °C for 30 min.The sterilized fish mixture was subjected to treatments involving the incorporation of a single starter culture containing Lactobacillus plantarum SK (5) at a concentration of 10% (v/b), as well as a mixed starter culture consisting of L. plantarum SK (5) and Pediococcus pentosaceus BP (20) at a concentration of 10% (v/w). Undertaking the fermentation of Bekasam was fermented for an interval of 8 days every 2 days, encompassing the quantification of total Lactic Acid Bacteria (LAB), pH, and Total Acid Titratable (TAT). The incorporation of single and mixed starters during fermentation resulted in consistent microbiological and chemical characteristics, characterized by an increase in the overall count of LAB and TAT, accompanied by a decrease in pH. The incorporation of a mixed starter resulted in a higher overall concentration of LAB and TAT, as well as a more rapid decrease in pH, when compared with the use of a single starter. The chosen treatment method involved the incorporation of a mixed starter possessing certain characteristics, including a moisture content of 66.56%, ash content of 5.92%, protein content of 23.06%, fat content of 3.96%, and sodium chloride content of 2.57%. Both L. plantarum SK(5) and P. pentosaceus BP(20) were deemed suitable for use as starters in bekasam fermentation

Graphical Abstract Highlight Research NaDES-based purification offers a sustainable and cost-effective method for extracting phycocyanin from Spirulina platensis. ChCl:Citric Acid (NaDES) achieved 2.3-fold purity (71.83%), surpassing ammonium sulfate precipitation (70.15%). Phycocyanin retained its structural integrity, with enhanced antioxidant activity (IC50 = 40.54 ppm) post-purification. The aqueous two-phase system (ATPs) efficiently separated impurities, improving extraction scalability. This method supports applications in nutraceuticals, cosmetics, and functional food industries as a green alternative. Abstract Phycocyanin, a pharmacologically potent blue pigment extracted from Spirulina platensis, requires optimal purity for effective utilization. Traditional purification methods, although effective, are impeded by time and cost constraints. Addressing this challenge, aqueous two-phase systems (ATPs) incorporating natural deep eutectic solvents (NaDES) emerge as promising alternatives. These systems offer operational simplicity and cost-effectiveness, ensuring efficient purification with high purity and optimal recovery of phycocyanin. This study investigated the impact of various types of hydrogen bond donors (HBD) within choline chloride-based natural deep eutectic solvents (NaDES) on the purification of phycocyanin. Phycocyanin was extracted from Spirulina platensis biomass through ultrasonication and purified using an aqueous two-phase system with various HBD of NaDES, including urea, glycerol, and citric acid. The experimental design adhered to a completely randomized design. The initial purity index and yield of crude extract phycocyanin were 0.54±0.02 and 12.79±0.27%, respectively. The NaDES system with ChCl:citric acid exhibited superior performance, demonstrating a high purity index and recovery (2.3-fold, 71.83±2.36%) compared to ammonium sulfate (1.5-fold, 70.15±4.10%). The obtained phycocyanin was partially pure compared to commercial phycocyanin (purity index: 1.60), as indicated by SDS-PAGE. Moreover, the antioxidant activity of phycocyanin was enhanced post-purification, evident in the IC50 value of 40.54 ppm. In summary, organic acid-based NaDES has proven effective in increasing the purity and achieving a significant recovery percentage of phycocyanin compared to conventional ammonium sulfate methods. The antioxidant activity of phycocyanin was enhanced after purification. These results indicate the promising potential of NaDES-based ATP systems for producing functional protein-based ingredients, exemplified by phycocyanin.
