Problems solved by technology

The good prospects for development and utilization make the natural resources of Polytubule algae unable to meet the potential development needs, so the development of methods that can be used for artificial cultivation and production is a forward-looking approach, but there is no relevant report on the artificial cultivation of Polytubule algae

Embodiment Construction

[0006] The inventor brought back the spores of Polytubella sporozoites collected from the seashore of Qingdao between March and April 2007, and selected healthy algae bodies therefrom. In the boiled and cooled seawater, scrub with cotton balls until there are no obvious miscellaneous algae and attachments; at this time, there are often a small amount of miscellaneous algae such as diatoms attached to the algae. It will multiply rapidly and affect the growth of Polytubule algae. In order to further clean the algae, immerse the brushed Polytubule sporozoites in clean sea water, and wash them several times with an ultrasonic cell disruptor. The power is generally 150 watts, and each time is 10 seconds. The time should not be too long to avoid heat generation. Too much damage to the algae, generally 3-5 times can remove all the algae, but after each cleaning, it should be replaced with clean sea water. Microscopic examination confirms that there is no algae attached. Take the cl...

Abstract

The present invention relates to a polysiphonous alga sporophyle direct seedling-forming method. It is characterized by that said method includes the following steps: selecting health alga body from wild population, using firstly-boiled lately-cooled sea water to wash the alga body until the heterogeneous alga is removed, then cleaning said alga body for 3-5 times by using ultrasonic wave until on the alga body the heterogeneous alga pollution is completely eliminated, using pulverizing machine to pulverize alga body, filtering said pulverized alga body by using screen cloth whose pore size is 120-130 micron, then making the obtained filtrate be passed through screen cloth whose pore size is 90-100 micron, culturing the obtained alga part in culture tank with 10-15 deg.C, light intensity is 2000-3000 lux, illumination time is 10-14hr, after 3-7 days, enough number of pseudorhizae and innovations with enough length can be grown on the alga part.

Description

technical field [0001] The invention relates to a method for directly forming seedlings of polytubella sporophytes. Background technique [0002] Polytubella is a class of red algae belonging to the Rhodophyta Eurythrophyceae Songosteocetaceae. Recent studies have shown that Polytubella has anti-bacterial and fungal, anti-herpes virus and antioxidant activities, and has cytotoxic activity against a variety of cancer cells (such as colon cancer cells, schwannoma cells), so in the development of seaweed drugs It has important development prospects; in addition, Polytubella is also rich in galactose sulfate, phycoerythrin and other substances, which also have important economic value. The good prospects for development and utilization make the natural resources of Polytubuleum unable to meet the potential development needs, so it is a forward-looking approach to develop methods that can be used for artificial cultivation and production, but there is no related report on the ar...
