Ethanol Pretreatment

In order to extract lycopene more effectively, this experiment focused on the optimization of ethanol pretreatment method to study the effects of ethanol treatment on the extraction rate of lycopene and its antioxidant activity. The test results show that 2 times ethanol treatment is very effective for improving lycopene yield. The optimum conditions of ethanol treatment are temperature 50 ℃, treatment time 1 time 2h, 2 times 2h, solid to liquid ratio is 1:12. The lycopene yield can be reached 20mg / 100g above.

Taking plateau red soil as research object, using the ultrasonic-assisted organic acid extraction the heavy metal zinc in it, and analyze the form of zinc. Results showed that the extraction rate can reach 68%, with the increase of time, the extraction effect of zinc is obviously enhanced in this method. Ultrasonic-assisted citric acid extraction soil can increase the extraction rate of exchangeable, bound to carbonates and bound to iron and manganese oxides relatively.

Osmotic Downshock

The simultaneously co-production of Poly-β-hydroxybutyrate (PHB) and ectoine in a process (PHB/Ect co-production) and co-products extraction have great significant for reducing the manufacture cost and promoting industrialization of PHB and ectoine. The pure aqueous extraction method based on osmotic downshock was used for the extraction of PHB/Ect co-products byH. salina. The effects of osmotic pressure, extraction temperature and extraction time on the extraction rate of PHB were investigated. The ectoine was extracted and purified by the techniques of hollow fiber and ion exchange. The optimal conditions for PHB extraction were osmotic downshock in pure water, extraction temperature at 60 °C and extraction for 4 h. The extraction rate of PHB was 87.5%. The extraction rate of ectoine was 84.2%.
