Abstract

The Covid-19 pandemic has increased human needs for nutrition including functional food and nutraceutical products in line with the need to boost immunity to resist viral infection, maintain a healthy life, and limit fatalities. 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. In general, producing functional nutritional products from  Aurantiochytrium microalgae requires several stages starting from the isolation and screening of microalgae, cultivation, extraction of the desired components and finally downstream processing for purification and packaging the product. Although Aurantiochytrium microalgae is found in the mangrove ecosystem, unfortunately, studies on the production potential of functional nutrients from microalgae Aurantiochytrium native strains from Indonesia have been rarely pubslihed. Therefore, it is expected that this study will become a fundamental basis for further research in this field and increasing attention for the production of functional nutrients from  Aurantiochytrium 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.

Abstract

Aurantiochytrium microalgae is recognized as heterotrophic microalgae enables to produce high economic value of lipids for the use in health care industries. This research presents the production of biomass containing lipids through the bioconversion of fruit waste using Aurantiochytrium microalgae. Aurantiochytrium microalgae isolate was obtained from isolated mangrove leaves in the mangrove forest of Bunyu Island, North Kalimantan. The production process takes place in three stages, namely standing culture (SC), pre-culture (PC), and main culture. The SC and PC stages took place 48 hours respectively, while the MC took place 120 hours. The source of nutrition at the main cultivation stage (MC) used monosodium glutamate (MSG) as a nitrogen source, while the carbon source was from fruit waste. Amount of 250 grams of fruit waste was mixed and blended, added with 250 ml of water and then sonicated. The mass ratio of nitrogen source and carbon source was 1:3. The maximum of observed microalgal cell diameters for each stage were 14.5 μm (SC), 19.2 μm (PC) and 25.5 μm (MC). Produced biomass in this experiment has the characteristics of a yellow emulsion liquid, pH 6.2, fishy smell and total dissolved solids (TDS) of 4,820 ppm and a wet biomass of 68 g/l
