Embodiment 1

[0033] This embodiment provides a method for cultivating microalgae using dynamic light. When cultivating microalgae, the culture solution of microalgae is stirred in a rotating and lifting manner, and dynamic light synchronous with stirring is used during stirring, that is, when stirring During the process, the position and angle of the light change synchronously with the rotation and lifting actions.

[0034] As mentioned above, the essence of microalgae culture is the conversion of light energy, and light is the key factor for the growth of microalgae. The quality of light conditions also has a crucial impact on the production of microalgae. By fully stirring the microalgae and changing the angle and direction of the light received by the microalgae at all times, the microalgae in different positions can receive more uniform light. , and form the turbulence required for microalgae cultivation by stirring, optimize the cultivation environment of microalgae, and increase the ...

Embodiment 2

[0039] figure 1 An overall structural axonometric view of the dynamic photobioreactor 1 is shown, figure 2 An axonometric view of the internal structure of the overall structure of the dynamic photobioreactor 1 is shown.

[0040] This embodiment provides a dynamic photobioreactor 1 , which includes a culture tank 11 , a light emitting unit 12 , light arm paddles 13 and a driving mechanism 14 . The light-emitting unit 12 is arranged on the light arm paddle 13, and the light arm paddle 13 is set in the culture tank 11, and the driving mechanism 14 can drive the light arm paddle 13 to rotate and lift.

[0041] As mentioned above, the dynamic photobioreactor 1 is used to cultivate microorganisms, and this embodiment takes the cultivation of microalgae as an example.

[0042] The cultivation tank 11 is a reaction vessel for cultivating microalgae, which is cylindrical in shape and can be made of light-transmitting material. After passing through the cultivation tank 11, natural ...

Abstract

The invention provides a dynamic photo-bio-reactor. The dynamic photo-bio-reactor comprises a culture tank and a light emitting unit; the dynamic photo-bio-reactor further comprises an optical arm blade propeller and a driving mechanism; the light emitting unit is arranged on the optical arm blade propeller; the optical arm blade propeller is arranged in the culture tank; the driving mechanism canbe used for driving the optical arm blade propeller to do rotating and hoisting movement in the culture tank. The invention further provides a method for culturing microalgae by utilizing dynamic light; a culture solution of the microalgae is subjected to rotating and hoisting type stirring; in a stirring process, dynamic light illumination which is synchronized with stirring is carried out. Thedynamic photo-bio-reactor and the method for culturing the microalgae by utilizing the dynamic light, provided by the invention, have the advantages of simplicity in operation, low cost and capabilityof effectively improving the yield of microorganisms (microalgae) cultured by the method.

Description

technical field [0001] The invention relates to the field of microorganism cultivation, in particular to a dynamic photobioreactor and a method for cultivating microalgae using dynamic light. Background technique [0002] Microalgae are capable of converting carbon dioxide into biofuels, food, feed, and high-value bioactives, as well as being used for bioremediation and as nitrogen-fixing biofertilizers. Microalgae can provide different types of renewable biofuels, including the extraction of biodiesel from microalgae oil, the production of methane after anaerobic digestion, and fuel ethanol, the production of bio-oil by hydrothermal cracking and liquefaction, and the production of bio-hydrogen by photosynthesis. [0003] Because microalgae have the characteristics of wide distribution, high photosynthetic efficiency, high oil content, short growth cycle, high oil area yield, strong environmental adaptability and do not occupy arable land, it is considered to be the most pot...
