Study On Production Lycopene By Fermentation And Extraction By Supercritical Co₂

Lycopene has predominantly functions of quenching singlet oxygen, scavenging of free radicals and reducing the communication between cells, consequently which could act great roles on preventing cancer and atherosclerosis. In this paper, such factors of its technical flow were investigated respectively as follows: synthesis of MPTA as a new bloking agents and accelerant and its influences on fermentation, the influences of Oxygen-vectors, Surface Active Agents on Lycopene's fermentation, and the effect factors of super-critical carbon dioxide extraction of Lycopene.MPTA is an amine compound, it ws often used to be an inhibitor from Lycopene to β-carotenoids. The experiment said that the enlist could come up to 70% with the help of synthetical MPTA by Williamson reaction.The study indicate that there is 38.3% improvement in the production of lycopene when 1.2mL/L MPTA was added to 2-day old culture of Blakeslea trispora.Blakeslea trispora is highly addicted to aerobic and viscoid medium microorganism, and it need a mass of dissolved oxygen in zymolytic process, especially in logarithm growth phase. Due to this issue, we have...
