Problems solved by technology

However, there is still a certain distance between the research on this algae and the commercial production at present. There are mainly the following problems in the production: (1) Haematococcus pluvialis is sensitive to environmental changes, has a short exponential growth period, and is resistant to bacteria and native algae. The ability of animals to pollute is poor, and they will lose their reproductive capacity in extreme environments, and it is difficult to establish a stable and efficient production technology system; (2) The cultivation period is long, the yield is low, the continuity is poor, and a large number of deaths occur during the stress process, which is not conducive to large-scale production. Scale training
(3) When cultivated in a large pond, the utilization rate of light energy is limited, which restricts the production efficiency of astaxanthin accumulation stage and increases the production cost
The study fo...

Abstract

An air lift optical bioreactor of the alga is made up of cultural tank, water treatment, light equipment, gas-supply equipment. The bioreactor has the simple structure and is easy to manipulate. Also we can get the culture the alga the whole day.

Description

technical field [0001] The invention relates to the field of biotechnology, more specifically to an airlift photobioreactor for high-density cultivation of Haematococcus pluvialis, which is applied to the high-density cultivation of Haematococcus pluvialis and the accumulation process of astaxanthin . Background technique [0002] Haematococcus pluvialis (Haomatococcus pluvialis) is a single-cell microalgae, which belongs to Chlorophyta, Volvox, Haematococcus, and Haematococcus in taxonomic status. It can accumulate a large amount of astaxanthin at a specific stage of growth, and is a promising microalgae. As an economical microalgae, it has the following advantages: 1) High economic value, according to the current international market price, the price of 1 kg of dry algae powder is about 20 US dollars or more; 2) The cost of breeding is low, only a small amount of nutrient salt and Certain temperature and light conditions; 3) As freshwater alg...
