Abstract

The invention belongs to culture of microorganisms, and particularly relates to a method for producing fucoxanthin by heterotrophic culture of smooth nitzschia. The method comprises the following steps: preparation of a seed solution, fermental cultivation, extraction of the fucoxanthin from fermentation liquor after fermentation is finished and the like. The problem that the biomass concentration of the smooth nitzschia, the yield of the fucoxanthin and the content of the fucoxanthin are low under the condition of heterotrophic culture in the prior art is solved. The method has the advantages that the content of fucoxanthin in prepared dry smooth nitzschia powder is high, the yield of the fucoxanthin is high, the fucoxanthin is safer than fucoxanthin from large seaweeds, and while the production efficiency is improved and the production cost is reduced, pollution risks in a culture process is greatly reduced.

Description

technical field

[0001] The invention belongs to the cultivation of microorganisms, and in particular refers to a method for producing fucoxanthin by using heterotrophic cultivation of Nishina smoothis. Background technique

[0002] Fucoxanthin (Fucoxanthin), also known as fucoxanthin and fucoidin, mainly comes from large algae and microalgae such as algae, diatoms, and golden algae. It is a natural carotenoid that participates in the photosystem of photosynthesis II's response. Because of its unique allene structure, fucoxanthin is an active molecule with strong antioxidant properties. In recent years, studies have found that fucoxanthin has a variety of functional activities in cells, animals and humans, including anti-oxidation, anti-inflammation, anti-cancer, anti-obesity, anti-diabetes, anti-angiogenesis and anti-malarial and other physiological activities, and It has a protective effect on organs such as liver, brain blood vessels, bones, skin and eyes. Based on the ...
