| 英文摘要 | The enzyme-assisted aqueous extraction of oil from wet microalgae was employed to avoid the energy consumption of a dewatering process. in this paper, oil-rich microalgae scenedesmus sp. g4 was hydrolyzed by enzyme mixtures for oil extraction. the results showed that the algae concentration had the greatest influence on yield of extracted oil, and the temperature and the ratio of enzyme mixtures affected the results as follows: the maximum yield of oil extracted from scenedesmus sp. g4 reached 86.1% under optimal conditions with an algae concentration at 2.5 g/l, temperature 30/50 degrees c, ph 3.5/4.5 and a cellulase:pectinase:hemicellulase ratio of 1:1:1 or 1:2:1 (w/w/w). the results also indicated that the enzyme mixtures had a significant impact on the integrity of microalgae cells and the crystallization index increased from 30.7% to around 36.0% after enzymatic hydrolysis treatment. the cell wall of scenedesmus sp. g4 has a high content of cellulose i and low crystallization, which is beneficial to the oil extraction by the enzyme-assisted hydrolysis method. |
