The total annual citrus production in the world is estimated to be in excess of 88 MMT, with 53 MMT of which is being orange. This corresponds to annual generation of 2.3 MMT (global production) and 0.8 MMT (US) of orange peel wastes.1 In this study, we used orange peel waste from a juice production factory to supplement the culture medium. The nutrients were extracted from the waste orange peel via aqueous extraction in the room temperature. After the optimization of extraction time, the orange peel extract was used for mixotrophic cultivation of Chlorella vulgaris. The initial nutrient content of the culture was of the follwing - 6 g/L glucose, 140 mg/L phosphate. After 7 days of cultivation, culture density reached a maximum of 2.8 (OD682). There results show that utilization of waste orange peel extract is an effective way to cultivate microalgae for biodiesel production in industrial scale. *1 MMT = 1000 MT
