Expression analysis for genes involved in arachidonic acid biosynthesis in Mortierella alpina CBS 754.68
The time courses for production of fungal biomass, lipid, phenolic and arachidonic acid (ARA) as well as expression of the genes involved in biosynthesis of ARA and lipid were examined in Mortierella alpina CBS 754.68. A significant increase in the arachidonic acid content in lipids that coincided with reduced levels of lipid was obtained. Reduced gene expression occurred presumably due to the ...
متن کاملArachidonic acid production by Mortierella alpina using raw crop materials.
BACKGROUND Arachidonic acid (ARA) is one of the three essential fatty acids, and it is important for human body to keep healthy and is widely used. At present, expensive materials such as glucose and yeast extract are generally reported to be optimal for ARA production. A new cost-effective fermentation process including cheaper material for ARA production is of great significance. METHODS Fe...
متن کاملStatistical Optimization of Arachidonic Acid Production by Mortierella alpina CBS 754.68 in Submerged Fermentation
Arachidonic acid is an essential fatty acid in human nutrition. In the present study, production of arachidonicacid by Mortierella alpina CBS 754.68 was evaluated in submerged fermentation. The fermentation variableswere selected in accordance with the Plackett-Burman (PB) design and further optimized via response surface methodology (RSM). Five significant variables, namely glucose...
متن کاملExpression of Vitreoscilla hemoglobin enhances production of arachidonic acid and lipids in Mortierella alpina
BACKGROUND Arachidonic acid (ARA, C20:4, n-6), which belongs to the omega-6 series of polyunsaturated fatty acids and has a variety of biological activities, is commercially produced in Mortierella alpina. Dissolved oxygen or oxygen utilization efficiency is a critical factor for Mortierella alpina growth and arachidonic acid production in large-scale fermentation. Overexpression of the Vitreos...
