A method and device for extracting natural blue pigment of marine streptomyces

Abstract

The invention provides a method and device for extracting the natural blue pigment of marine streptomyces, comprising a feeding port, a control panel, a liquid storage tank, a spraying device, a stirring device, a suction filtration device, an ultrasonic crushing tank, an extraction tank, a centrifugal tank, Crude liquid collection tank and pH purification collection tank, the extracellular fermentation liquid of marine Streptomyces and intracellular Streptomyces two different blue pigments correspond to adopt different processing methods, using the blue pigment of marine Streptomyces in different The characteristics of its aggregation form change under the pH value, it is repeatedly extracted and purified, and at the same time, in order to prevent the cells from accumulating on the suction filtration membrane and reduce the filtration efficiency, a stirring device is designed. The design of the stirring device increases the intracellular chain. The mold filtration speed is improved and the filtration operation is simplified. The method and device for extracting the natural blue pigment of the marine streptomyces provided by the invention have a high utilization rate of the marine streptomyces, fast production efficiency, and higher purity of the obtained blue pigment.

Description

technical field [0001] The invention relates to the field of microbial pigments, in particular to a method and a device for extracting natural blue pigments from marine streptomyces. Background technique [0002] Pigments are widely used in food, medicine, cosmetics, health products and other industrial production. With the improvement of people's living standards, the demand for pigments has increased sharply, and synthetic pigments will not be able to occupy the pigment market because they have no nutritional value and have toxic effects. Compared with animal and plant pigments, microbial pigments have the advantages of not being affected by factors such as time, space and environment, and can be produced on a large scale using fermentation equipment. As one of the three primary colors, blue is doomed to have a huge application prospect and potential. Blue pigment can be matched with red and yellow pigment to modulate various hues. [0003] As a natural pigment, microbia...

AI Technical Summary

Problems solved by technology

However, there are still many problems in the current industrialized production of blue pigment, such as imperfect production process, high energy consumption, low labor production efficiency, insufficient yield, purity and quality, so it is urgent to screen and domesticate from new technology, new equipment and high-efficiency strains. Wait for several aspects to solve these problems, so as to achieve the economic benefits of increasing production and income
