The invention relates to application of synechocystis in removal of cadmium ions and a method for reducing cadmium ions in an environment, and the method comprises a step of culturing synechocystis in the environment. By means of the method, the concentration of free-state cadmium ions in the environment can be reduced to about 10 micrograms/L, and cadmium in the environment is greatly reduced after cadmium particles outside microalgae and cells are removed. Although the concentration of cadmium ions which can be treated by the method provided by the invention is relatively low and is 1mg/L or below, the concentration of the cadmium ions in the supernatant can be finally reduced to a very low value, so that the method can be used for further cadmium removal after primary cadmium removal of a water sample, and extremely low cadmium emission is realized.

The invention relates to application of boron nitride in microalgae culture and a method for culturing microalgae, which comprises the step of adding boron nitride into a culture system. By constructing a hexagonal boron nitride-cyanobacteria co-culture system and combining the carbon dioxide adsorption performance of a nano material and the biological directional synthesis capability of cyanobacteria, more efficient carbon dioxide capture and conversion are realized, and meanwhile, the growth speed and biomass of cyanobacteria and the yield of a target product are also improved. The innovative strategy not only can enhance the photosynthetic carbon sequestration efficiency of cyanobacteria, but also provides a new technical route for promoting green and low-carbon development, and gives consideration to both high economic benefit and low-carbon environmental protection.

The present invention relates to a cell culture composition comprising an extract of thraustochytriaceae microalgae. It has been found that the proliferative capacity of muscle cells is enhanced when the muscle cells are cultured in a culture medium according to the present disclosure comprising an extract derived from a microalgae biomass belonging to the Thraustochytridae family. Thus, the cell culture composition comprising the microalgae extract can be used as a substitute for fetal calf serum in the cell culture medium component.

The invention discloses a method for assisting microalgae oil production by nitrogen-fixing bacteria and treating fermentation waste gas at the same time. The method comprises two stages of microalgae breeding and co-culture oil production. In the breeding stage, the microalgae take CO2 in fermentation waste gas which is not pretreated as a carbon source, and high-density culture is realized in a nitrogen-containing culture medium. When the nitrogen source in the culture medium is consumed, inoculating multifunctional nitrogen-fixing bacteria into a culture system and co-culturing with the microalgae. Nitrogen in the fermentation waste gas is converted into a nitrogen source of the microalgae under the action of nitrogen-fixing bacteria, so that the concentration of the low nitrogen source is maintained to promote the microalgae to produce oil, and secretions mainly comprising extracellular polymeric substances and volatile organic compounds derived from the fermentation waste gas, which are generated by microalgae culture, are decomposed. Effective treatment of fermentation waste gas and high-density culture of microalgae are achieved, the oil content of the microalgae is increased, culture water can be repeatedly used by reducing the content of residual organic matter and total nitrogen, the problem that the amount of microalgae culture wastewater is large is solved, and good environmental benefits and application prospects are achieved.
