Riboflavin production by environmental yeasts isolated from Ae. albopictus larvae and breeding-site waters. Yeasts were grown in minimal medium under constant agitation for 24 h in the dark at 28 °C. Riboflavin measurements were performed on the culture supernatant after pelleting the cells, using a fluorometer (450-nm excitation, 525-nm emission). The cell counts were estimated using a cell counter
