An Online Respiratory Quotient-Feedback Strategy of Feeding Yeast Extract for Efficient Arachidonic Acid Production by Mortierella alpina
Mortierella alpina (M. alpina) is well known for arachidonic acid (ARA) production. However, low efficiency and unstableness are long existed problems for industrial production of ARA by M. alpina due to the lack of online regulations. The aim of the present work is to develop an online-regulation strategy for efficient and stable ARA production in industry. The strategy was developed in 50 L f...
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 کاملAn efficient multi-stage fermentation strategy for the production of microbial oil rich in arachidonic acid in Mortierella alpina
BACKGROUND Fungal morphology and aeration play a significant role in the growth process of Mortierella alpina. The production of microbial oil rich in arachidonic acid (ARA) in M. alpina was enhanced by using a multi-stage fermentation strategy which combined fed-batch culture with precise control of aeration and agitation rates at proper times. RESULTS The fermentation period was divided int...
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...
