Production method of cylindrotheca clostetium

Abstract

A production method of cylindrotheca clostetium comprises the following steps: respectively connecting a culture medium charging system, a material liquid collecting system, and an air supply system with a hanging-bag photo bioreactor so as to form a culture system of cylindrotheca clostetium; adding cylindrotheca clostetium after expansion culture and the culture medium into the reactor; continuously charging the culture medium with a constant flow rate and continuously injecting air; during the culture process, controlling the seawater temperature to be 10 DEG C-35 DEG C, the salinity to be20-30, and the illuminance to be 3000-10000 lx, controlling the pH of the culture medium to be within 7.8-8.4; continuously collecting mature cylindrotheca clostetium under the action of continuous air injection. The invention not only establishes a mature cylindrotheca clostetium expansion culture method, but also establishes a fully-closed continuous culture method of cylindrotheca clostetium based on the established expansion culture method, and has the advantages that the method accords with the physiological characteristics and ecological habits of cylindrotheca clostetium; during cylindrotheca clostetium culture, the whole culture process is clean, continuous, controllable, has high culture efficiency, and is applicable to the characteristics of production application.

Description

technical field [0001] The invention relates to a production method of Cylindrical algae, which is suitable for cultivating and collecting Cylindrical algae in production. Background technique [0002] Cylindrotheca (Cylindrotheca sp.) taxonomic status as diatoms, diatoms pinnata, phyllophytes, rhizophyceae, Cylindrotheca genus. The cells are long, with a round end surface and elongated ends, in the shape of a mouth or a head. The cells are 69.5 microns long and 4.5-5 microns wide. There are 2 or more pigment bodies, located in the main body of the cell, not deep into the mouth. The total lipid content of Cylindrical sp. accounts for 16% to 37% of the dry weight, and the EPA content accounts for 3.36% to 15.9% of the total fatty acids. It has high nutritional value and is suitable for being used as bait organisms such as sea cucumbers and abalones, and can also be used as production organisms. Raw material for diesel. Cylindrical sp. grows in the natural environment and ...

AI Technical Summary

Problems solved by technology

The cultivation of Cylindrical algae has not been established, whether it is laboratory cultivation or productive cultivation, especially its continuous cultivation method is pioneering, and there is no similar technology in China for comparison

In the actual production and scientific research process, Cylindrophyta is a benthic algae with large individuals, so it is easy to settle at the bottom of seawater, and in its life stage, it has high requirements for nutrients, carbon dioxide, dissolved oxygen and light intensity , there are also relatively strict requirements on the pH value of seawater, and a series of conditions need to be met as a productive culture, and when such conditions are difficult to meet for a while, it will make it difficult for the cultivation of Cylindrical algae to meet the requirements, or even difficult. Cultivate success
