6th International Conference on Energy and Environment Research, ICEER 2019, 22–25 July, University of Aveiro, Portugal Enhancing carbohydrate productivity from Nannochloropsis gaditana for bio-butanol production

摘要

It presents an effective bio-butanol production with various acid hydrolysis treatment strategies Hsub2/subSOsub4/sub, HCI and Hsub3/subPOsub4/sub (1, 2, 3, 4 and 5%) from Nannochloropsis gaditana grown under different light intensities (40, 80, 120 and 160 μ m olm ? 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 160 μ m olm ? 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.
