Abstract

Mangrove forests have a very diverse microbial population. Among these microbes, some have the ability to convert mangrove forest organic waste into useful nutrients for the sustainability of the mangrove ecosystem. One of the species that has this ability is the marine yeast Rhodotorula sp. Apart from this ecological role, the yeast Rhodotorula sp. reported to have a lot of biotechnology potential, including as a producer of lipid omega-3, carotenoids, anti-bacterial, plant growth promoter, anti-cancer, biosurfactant, and a very potential workhorse for biotechnology applications. As a country that has the largest mangrove forest in the world, Indonesia has not reported much and has not intensified the use of marine yeast Rhodotorula sp. from Indonesian mangrove forests as a bioresource for high-value strategic products. This study aims to isolate the marine yeast Rhodotorula sp. from the mangrove forest of Pari island, Jakarta and reviewing the ecological role and biotechnological potential of these species. Marine yeast Rhodotorula sp. obtained will be cultivated and exploited its biotechnology potential in the future

Abstract

Thrautochytrids are often called heterotrophic microalgae that have a lot of omega-3 docosahexaenoic acid, or DHA. These microbes are found in many mangrove forest areas, including Indonesia, which has the biggest mangrove forests in the world. Indonesia is also beginning to look for useful microbes in these environments. The goal of this study was to find and identify a type of Thrautochytrid called Aurantiochytrium sp. in the mangrove forests of Tidung Island, part of the Thousand Islands near Jakarta. This area has never been studied for this type of microbe before. The study found two isolates of Thrautochytrids, named Aurantiochytrium sp. PTD5 and PTD6. These were identified by looking at the phylogenetic tree made from 18S rRNA sequences. The phylogenetic tree shows that PTD5 and PTD6 are closely related to other Aurantiochytrium strains like SR21 and BL10, which are widely used in research for making omega-3 DHA lipids.
