Extract of mung bean sprout has been used in laboratories in Indonesia as an inexpensive alternative to growth medium for fungi. The extract is assumed ]able to give a same fungal growth profile as the commercial medium, such as Potato Dextrose Medium and Malt Extract medium. But there has been no empirical evidence of the assumption. The project aims to compare the growth of yeasts and moulds in the medium of mung bean sprouts and commercial mediums. The resulting data provide information about the suitability of the extract as an alternative medium of fungi growth.
Flower nectar and nectar is an environment that contains high sugar making it a suitable habitat for osmophilic yeasts. These yeasts are less studied in Indonesia, hence this project aims to study the diversity and potential of these yeasts.
Oleaginous yeasts has a potential application in feedstock production in biodiesel industry. Several oleaginous yeasts have been isolated from Indonesia, however their lipid production has not been studied. This project aims to optimize the yeasts lipid production medium as part of optimization effort to obtain a high lipid production.
