Enhancing carbohydrate productivity from Nannochloropsis gaditana for bio-butanol production
Melih Onay
Abstract
It presents an effective bio-butanol production with various acid hydrolysis treatment strategies H2SO4, HCI and H3PO4 (1, 2, 3, 4 and 5%) from Nannochloropsis gaditana grown under different light intensities (40, 80, 120 and 160μmolm−2 s−1). Microalgae were cultivated at 24 ± 2 with f/2 medium for control. According to our results, HCI 3% yielded the highest carbohydrate productivity with (21.3 ± 0.9 %) and bio-butanol production (2.9 ± 0.24 g/L). In addition, we obtained the highest carbohydrate content at 160μmolm−2 s−1 of light intensity. These findings suggest that Nannochloropsis gaditana can be used for effective carbohydrate content and large scale bio-butanol production in the future.
