Cultivation of Chlorella vulgaris Using Plant-based and Animal Waste-based Compost: A Comparison Study

摘要

Utilizing compost derived from waste offers an alternative nutrients source to cultivate microalgae for biofuel production. This is because compost is a low-cost nutrients source which contains high amount of nutrient composition that suitable for microalgae cultivation. Thus, in the present work, plant-based compost and animal waste-based compost were used to cultivate Chlorella vulgaris. The results shows that C. vulgaris favoured to grow at the following condition: 50 ml amount of goat waste-based compost, under pH of 9, and illuminated continuously for 15 days using fluorescent light. Based on these cultivation conditions, 30 % of lipid was successfully extracted from the dried microalgae biomass.
