The present invention provides a liquid for preserving cornea for medium period and a preparing method thereof, and relates to a liquid for cornea material. The invention provides the liquid for preserving cornea for medium period and the preparing method thereof, wherein the liquid has the advantages of longer storing time, higher quality, no pollution and relatively lower cost compared with theprior liquid for preserving cornea for medium period. The liquid for preserving cornea for medium period contains culture solution, thickening agent, bovine serum, amino acid, antibiotic, acid-alkalimodifying agent and cell nutrition components. According to the formula of liquid for preserving cornea for medium period, the thickening agent, the bovine serum, the amino acid, the antibiotic and cell nutrition components are added into the culture solution for mixing to uniform. The pH value is adjusted to 7.2-7.4 with the acid-alkali modifying agent. The osmotic pressure is adjusted to 350-380mOsm / L with an osmotic pressure buffering agent. The liquid for preserving cornea for medium period is obtained after membrane filtering for sterilizing.

The present ivnention relates to the method of promoting haemtococcus pluvialis multiplication to produce pure strain in a controllable all-weather closed large-scale photobiological reactor system. The system has main reactor made of transparent material, outside controllable lighting facility, speed regualting vane wheel stirrer, water rolling wheel, bacteria-free ventilator, oxygen system, salty and fresh water nutritious liquid compounding and temperature controlling system, cleaning and sterilizing system. It can speed up the multiplication of haemococcus pluvialis, shorten the culture period and obtain pure strain.
