Embodiment

[0065] Take the production of Nostoc sp., which can form large colonies, as an example. The algae species are collected from Fubo Mountain in Guilin, and the purified algae species are obtained after separation and purification in our laboratory.

[0066] The medium used is the preferred medium: NaNO 3 0.1g / L -1 , Ca(H 2 PO 4 )2 0.1g / L -1 , K 2 Mg(SO 4 ) 2 0.08g / L -1 , Na 2 SiO 3 0.05g / L -1 , Na 2 CO 3 0.15g / L -1 ,FeCl 2 4mg / L -1 , H 3 BO 3 8mg / L -1 , MnCl 2 4H 2 O 5mg / L -1 1, ZnSO 4 ·7H 2 O 0.3mg / L -1 ,CuSO 4 ·5H 2O 0.1mg / L -1 , Na 2 MoO 4 2H 2 O 0.04mg / L -1 , CoCl 2 ·6H 2 O 0.02mg / L -1 .

[0067] The track-type culture pool 1 used is 70m long x 12m wide x 0.5m deep, with an inverted V-shaped steel frame on the top, covered with 60 mesh insect nets, and a flat sunshade net is added 1m above the highest point of the insect net. The sunshade net is electrically adjustable. , in sunny weather, 80% shade is applied from 11:30-13:30 every da...

Abstract

The invention provides a high-efficiency large-scale method for culturing algae. The method comprises the following steps: pre-treating a culture pool and pre-treating water for cultivation, adding amedium in the culture pool, and inoculating the algae species in the culture pool according to inoculation density; performing real-time monitoring on algae groups size, and luminous intensity, temperature, and pH value in the culture pool as well as photochemical active index of algae cell PSII, and performing protection adjusting measurement according to the monitoring data. The method can realize effective suspension of algae at each growth period, and can efficiently use light, nutrition and CO2 to realize rapid growth. The obtained algae biomass can produce functional food, a food raw material, bait, a high added value secondary metabolite and biodiesel.

Description

technical field [0001] The invention relates to the technical field of algae production, in particular to a method for high-efficiency large-scale cultivation of algae. Background technique [0002] Algae are low-level photoautotrophs without roots, stems and leaves. They have the characteristics of small size, high photosynthetic efficiency, wide range of adaptation to the environment, and high yield per unit area. Large-scale cultivation and comprehensive development and utilization of algae is one of the effective measures to solve many problems faced by human beings, such as food, energy, environment and health. For example, chlorella, spirulina, Haematococcus pluvialis and Dunaliella salina, which have been commercially produced, can provide high-quality protein, lutein, astaxanthin, EPA and DHA, and are high-quality functional foods and bait. [0003] The raceway pool is currently the most economical and effective outdoor large-scale cultivation facility for algae. I...
