In this regard, the choice to use functional food and nutraceuticals seems to be a promising panacea. This paper aims to examine the potential of the microalgae species Aurantiochytrium, which is commonly found in the mangrove ecosystem. This microalgae species has received a lot of attention from researchers because of its high content of lipids and other high-value-added components as well as its fast growth and resistance to environmental stress. With current bioprocess technology, Aurantiochytrium microalgae can be deployed to produce high-value-added components such as astaxanthin. During the current pandemic, the need for this product is increasing as raw material for drugs, health supplements, antioxidants, and vaccine adjuvants that are in direct contact with efforts to combat the human coronavirus and prevent the spread of viral diseases. Due to its strategic position, several large companies have positioned as pioneers in the production of these nutritional products to supply the desired products to help international programs fight the pandemic. In general, producing functional nutritional products requires stages starting from the isolation and screening of microalgae, cultivation, extraction of the desired components to product packaging. Although Aurantiochytrium microalgae are found in the mangrove ecosystem, unfortunately, studies on the production potential of functional nutrients from microalgae Aurantiochytrium native strains from Indonesia have never existed until now. From this study, it is expected that this study will become a fundamental basis for opportunities for further research in this field and increasing attention for the production of functional nutrients from microalgae isolated from mangrove forests in Indonesia. An early insight into bioprocess technology modes such as appropriate isolation techniques, cultivation, and extraction to produce astaxanthin is provided.","PeriodicalId":118085,"journal":{"name":"CHEMICA: Jurnal Teknik Kimia","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116548547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest yield was found in 100 g, 450 W, and 90 min of 0.1392% based on experimental data. In addition, RSM using the quadratic model predicted that optimal condition at 88.09 g, 474.94 W, and 99.53 min was 0.1430%, respectively. An ANOVA analysis resulted in a p-value of less than 0.05 with a high determination coefficient (R 2 = 0.9971). It indicates that this model gives a significant response and has good accuracy. Furthermore, the error rates between experimental data and the predicted model were less than 5%.
