湿藻藻泥乙醇脱水干燥法的研究
Study on dehydration method of wet algae using ethanol
摘要
Abstract
[Objective]To effectively decrease the cost of dehydration and desiccation of wet Chlorella sp.[Methods] Paste for lipid extraction,the wet microalgal paste was dehydrated and desiccated by ethanol in this study.Chlorella was cultivated in BG11 culture medium and the wet algal paste was collected by centrifugation of algal solution.The effect of ethanol concentration,volume ratio of ethanol and water and dehydration time on water content of algal paste were investigated and the effect of water content in algal paste on lipid extraction ratio was also studied.[Results]The water content of wet Chlorella paste decreased from 89.04 % to 30.1 % when the ethanol concentration,volume ratio of ethanol and water and dehydration time were 80%,1∶1 and once,respectively.[Conclusion]Besides,the effect of water content in algal paste on lipid extraction ratio was insignificant when the water content was below 40%.It was meant that algal paste with water content of no more than 40% after dehydrated and desiccated by ethanol could be used for the lipid extraction.关键词
