Description

High yield DHA's splits algae strain of kettle algae and fermentation process thereof
Technical field
What the present invention relates to a kind of high yield DHA splits algae strain of kettle algae and fermentation process thereof.
Background technology
Docosahexenoic acid (DHA) mainly is present in human brain grey matter and the retina, be to keep the metabolic indispensable fatty acid composition of human body normal physiological, in infant's brain and eyesight growth, have very important physiological action, and can treat cardiovascular disorder, improve body immunity etc.DHA causes the great interest of people because of its distinctive physiological regulation function and is widely used.
The tradition source of DHA is fish oil, but the polyunsaturated fatty acid that extracts from fish oil (PUFAs) exists the output shakiness, yield is low, cost is high and contain other problems such as ω-6PUFAs, and along with the growing tension of fishing resources, oneself can't satisfy the growing market requirement traditional DHA resource.Therefore, the exploitation DHA newborn resource oneself become new research focus.Microbial fermentation is produced DHA becomes one of focus of domestic and international research with its special advantages, wherein utilizes little algae to cultivate production DHA and has bigger advantage and produce potential.
Little algae has that growth cycle is short, reproduction speed is fast, plasticity-is strong, nutritive factor is required characteristics such as simple, and part can reach high density fermentation by the control of biological engineering method and culture condition and cultivates.Found at present to be rich in polyunsaturated fatty acid (PUFAs) in multiple little algae, as split kettle algae, Crypthecodinium cohnii etc.Little algae is the initial production person of polyunsaturated fatty acid in the marine food chain, many saturated fatty acids DHA in some frustule, EPA content are higher, its relative content is up to the 5%-6% of dry cell weight, and contained polyunsaturated fatty acid kind is more simple, the separation of carrying out single component is purified relatively easy, thereby to utilize marine microalgae to produce polyunsaturated fatty acid be a very promising commercial field.Little algae oil has been widely used in fields such as medicine, food, makeup, feed because of being rich in polyunsaturated fatty acid.
It is abundant to split in the kettle frustule DHA content, and other unsaturated fatty acid content is very low.This algae is safe in utilization, and it has carried out a series of security detection to white mouse, rabbit humans such as Hammond, does not find any toxic side effect.The security of splitting the kettle algae has obtained the approval of U.S. food and medicine portion (Food and Drug Administration).The research that kettle algae fermentation culture is produced DHA is split in existing more utilization both at home and abroad at present, but has the not high problem of output mostly.T.Yokocki etc. adopt several kinds of carbon source and nitrogenous source counterincision kettle algae Schizochytriumlimacinum SR21 to be optimized cultivation in shaking bottle, and the DHA production peak that obtains is 4g/L.People such as Kw Fan are that kettle algae (Schizochytrium mangroves) is split in carbon, nitrogenous source cultivation with glucose and yeast extract, and the output of DHA only is 2.79g/L.The output of DHA is not very high in more than cultivating, and this also has direct relation except outside the Pass having with selected algae strain with culture process.
