Some Basic Knowledge of Photo Bioreactor

As an emerging energy technology, biotechnology has attracted much attention since the industrial revolution, and the support of the pilot fermenter as the device support of biotechnology, and bioreactor in biotechnology is also making rapid progress. As one of the biological pilot fermenters of microalgae medium, the photo bioreactor is one of them. It uses the principle of photosynthesis, which translates the optical energy into chemical energy. Through the metabolism of microorganisms, carbon dioxide is converted into biofuels.

Due to the decrease in non -renewable resources such as oil and the urgent needs of low -carbon environmental protection economy, biological energy has become the focus of R & D in various countries, but most of the current biomass energy sources are prepared by crops and limited land resources. Limited. The microalgal is a type of chlorophyll single -cell creature. It can be self -cultivation, many types, wide distribution, and fast growth. It can also use CO2, which is conducive to the realization Suitable for sustainable development of biomass.

This article will introduce some of the basic knowledge of photo bioreactor.

1. What is the photo bioreactor?

Photo bioreactor refers to a types of bioreactor that can be used for optical microorganisms and its tissue or cell culture. This reactor has a similar structure to the general biological reactor. Under general conditions, a certain amount of light, temperature, and nutrients are required to cultivate and control the system’s environment.

The photobioreactor is a complete culture system, in addition to the main body of the reactor, there is a ventilation part, a lighting system and a measuring device. The ventilation part is generally composed of an inflatable pump or a carbon dioxide cylinder and a gas distribution device, a filter, a flow meter, a gas sparger and a humidifier; The lighting system consists of two parts: a light source and a timer.

The research of the reactor has begun to face the oil crisis in the world. At that time, scientific researchers mainly conducted a lot of research with green algae. The main purpose was to study whether it could replace oil resources as energy. With the continuous deepening of research, in the 1950s, people already had a certain degree of grasp of the photo bioreactor.

However, at this time, the various types of bioreactors that people studied were mainly based on the theoretical test of the theoretical test. Study, no type of photo bioreactor is used in practice. Open -type optical biochemical -related equipment requires that it is not as precise as a closed reactor. The closed photo bioreactor is mainly used for the large -scale culture of a variety of microalgae, such as sparrows, small ball algae, and salt algae, and has achieved good results.

The main feature of the closed photo bioreactor, as its name implies, is that it is sealed and isolated from the external environment. It is built with transparent materials and is mainly glass materials. This is conducive to the internal microorganisms to get full light. Another point is to observe the phenomenon of reaction changes inside the biological pilot fermenter.

Compared with an open reactor, the main advantage of the closed photo bioreactor is that it can achieve a certain degree of continuous production, and because it is isolated from the external environment, it is not easy to be affected by the external environment. It can be able to be able to be affected by the external environment. Follow the established targets of microorganisms, and the application range of this bioreactor is relatively wide, the efficiency of hydrogen production is relatively high, and of course the purity of hydrogen production is relatively high.

However, the construction cost of the closed photo bioreactor is relatively high, and it is possible to complete it with more investment, once the photobioreactor is built, it can effectively control the temperature in the reaction process and the conditions for the growth of related microorganisms, and it is easy to operate, and can also reduce environmental pollution to a certain extent.

2. What are the applications of photo bioreactor?

(1) Energy field: Photo bioreactor can be used for research on biomass energy production and becomes a way to solve the energy crisis; (2) The food industry: The bioreactor can be used to make food additives, feed, etc.;(3) Industrial materials: Photo bioreactors can be used in the production of high -value compounds, microbial engineering in the pharmaceutical industry, etc.; (4) Ecological and environmental protection:The bioreactors can be used in the fields of urban optical biological solid carbon, water purification and marine photosynthesis.

3. Advantages of photo bioreactor

(1) Environmental protection Energy saving: Photoric reactor is a green and environmentally friendly production method. The use of solar energy as energy and no need for fossil fuel; (2) High biomass yield: The biomass yield of photo bioreactor is much higher than that of traditional culture methods; (3) High efficiency of microbial fermentation: Microbial fermentation efficiency in photo bioreactors, low cost, and high purity of fermentation products.

4. The development trend of photo bioreactor

The first is modularization. In the future, the photogen reactor will tend to modular design and be assembled as needed. Made in;

The second is new materials. With the continuous expansion of the application of photo bioreactor, various new materials are also applied to the manufacturing of biological pilot fermenters;The third is intelligent, intelligent design helps bioreactors to improve design through data analysis and improve production efficiency.

At present, the commonly used photo bioreactors in microalgae are two categories: open and closed types. The open -type bioreactor is simple, convenient to operate, and low operating costs. The closed photoretical reactor is mainly used in laboratory or small -scale cultivation of microalgae. The manufacturing, operation and maintenance costs are higher than the former, but it can better control the cultivation conditions and have better research value.

As a high -efficiency photosynthetic microorganism, photo bioreactor not only has important value in scientific research, but also shows great potential in industrial production and environmental protection. Through continuous technological innovation and optimization, photo bioreactors will play a more important role in the future bioreactor of biotechnology field.
