A photobioreactor (PBR) refers to any cultivation system designed for growing photoautotrophic organisms using artificial light sources or solar light to facilitate photosynthesis. Photobioreactors are typically used to cultivate microalgae , cyanobacteria , and some mosses . [ 1 ]

May 19, 2024 · A photobioreactor is a device used to cultivate microorganisms using light as an energy source. The microorganisms, usually algae or cyanobacteria, are grown in a culture medium, typically a liquid or gel.

Photobioreactor (PBR) is the most critical equipment for microalgal photosynthetic fixation of CO 2. It provides suitable environmental conditions, such as CO 2 , light and nutrients, for microalgal growth.

Oct 27, 2021 · Photobioreactors are an attractive choice to perform microalgae cultivation and biocatalytic processes in an efficient way, sometimes even in a large-scale. Although photobioreactors have been used for years, they are still being studied and improved using different shapes and illumination techniques in order to optimize the process.

A photobioreactor supplies light and CO2 to microalgae and other phototrophic organisms and cells. Supplied with nutrients the algae grow and form a dense liquid. After the maximum cell count has been reached, the biomass is harvested by centrifuge or sieves.

The ability to cultivate monocultures of algae with high biomass yields and significantly smaller footprints has made photobioreactors a very attractive technology for speci c applications. This chapter deals with photobioreactor design, application, efciencies, and …

Sep 8, 2023 · On the other hand, a photobioreactor is a specific type of bioreactor designed to cultivate photosynthetic microorganisms, such as algae and cyanobacteria. The primary source of energy in a photobioreactor is light, usually from natural sunlight or artificial lighting, which drives the photosynthesis process in the microorganisms.

This fact sheet will focus on photobioreactor design and operation. Photoautotrophic microalgae can be grown in open or closed photobioreactors. Reactors can be operated in continuous, batch or semi-continuous mode and can be installed indoors or outdoors.

In this study, we simultaneously compared the performance of four pilot-scale outdoor photobioreactors with Nannochloropsis sp. under identical climatological conditions in The Netherlands.

A photobioreactor designed for the purpose of microalgae cultivation and hydrogen production has been thoroughly described. The photobioreactor consists of a culture vessel with a flat plate design, a stand with a motor for agitation of the culture, a gas collection system, and a …

Photobioreactors are specialized bioreactors for culturing phototrophic organisms. Given the correct conditions, almost any algae, cyanobacteria, seaweed, or plant cell can be grown efficiently in a photobioreactor.

Photobioreactors-based production of photosynthetic microorganisms furnish several advantages as minimising toxicity and providing improved conditions. However, the designing and scaling-up of photobioreactors (PBRs) remain a challenge.

Apr 12, 2023 · Photobioreactors are closed systems used for growing microalgae or other photosynthetic organisms. They are designed to provide optimal conditions for photosynthesis, such as light, temperature, and nutrient availability. PBRs can range in size from small laboratory-scale systems to large industrial installations.

Jan 14, 2024 · Full-scale phototrophic cultivation of microalgae and cyanobacteria can be done in open ponds or closed photobioreactor systems, which have a broad range of volumes. This review focuses on laboratory-scale photobioreactors and their different designs.

Jan 1, 2023 · A photobioreactor (PBR) is a sealed, illuminated culture vessel that utilizes a light source to cultivate phototrophic microorganisms and these organisms use photosynthesis to generate biomass from light and carbon dioxide.

6 days ago · This paper proposes an innovative solution to the growing issue of greenhouse gas emissions: a closed photobioreactor (PBR) façade system to mitigate greenhouse gas (GHG) concentrations. With digital fabrication technology, this study explores the transition from traditional, single function building facades to multifunctional, integrated building systems. It …
