A method for mixed fermentation of golden algae and photosynthetic bacteria

Abstract

The invention provides a mixing fermentation method of chrysophyceae and photosynthetic bacteria, which belongs to the field of biotechnology. The invention concretely provides the mixing fermentation method of isochrysis galbana and ectothiorhodospira shaposhnikovii, isochrysis galbana and ectothiorhodospira shaposhnikovii are respectively subjected to seed activation, culture, and then mixing fermentation in an illuminating fermentation tank, so that isochrysis galbana content is greatly increased which is 5-10 times of that through normal culture.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and in particular provides a method for mixed fermentation of Chrysophytes and photosynthetic bacteria, in particular a method for mixed fermentation of Isochrysis globosa and Exothorhodospiri. Background technique

[0002] Isochrysis globosa belongs to Chrysophyta, Purinellaceae, Isochrysophyceae, Isodinophyceae. It has the characteristics of thin cell membrane, no cell wall, high protein content, and easy digestion and absorption by fish, shrimp, crab and shellfish. It is widely used in many microalgae in the production of aquatic economic animals. Chrysophylla is small in size, has no cell wall, thin cell membrane, It is easy to digest, high in oil and polyunsaturated fatty acid, and has become a kind of economical algae with high research value. However, Chrysophytes have strict requirements on temperature, light intensity and nutrient factors, and are easily polluted by various microorganisms s...
