Photobioreactors for microalgae cultivation – An Overview

Photobioreactors for microalgae cultivation – An Overview

The full text of this article hosted at iucr.org is unavailable due to technical difficulties. Photobioreactors have been used extensively for the cultivation of microalgae for a variety of applications from biofuels to high value products. The ability to cultivate monocultures of algae with high biomass yields and significantly smaller footprints has made photobioreactors a very attractive technology for specific applications.

Photobioreactors (PBRs) are equipment of central importance for the massive cultivation of microalgae, providing controlled conditions for high cell productivity. There are a few popular PBR designs, with contrasting advantages and limitations, such as poor light distribution, mass transfer, or hydrodynamic behavior. Due to the environmental concerns in recent decades and the discovery of … Biogas upgrading in algal-bacterial photobioreactors is based on the simultaneous photosynthetic fixation of CO 2 by microalgae and the oxidation of H 2StoSO 4 2− by sulfur oxidizing bacteria promoted by the high dissolved oxygen (DO) concentration present in the cultivation broth as a result of photosynthesis (Posadas et al., 2017, 2015 ...

Experimental data and model results presented in Fig. 4 also show that for biotechnologically relevant culture densities corresponding to c NG > 0.3 kg(dw) m −3, c IGV > 1.5 kg(dw) m −3, and to c PL > 0.3 kg(dw) m −3 in the respective photobioreactors the algal growth was always light-limited, because the specific growth rates stayed below 2/3 of the maximal growth rate for irradiances ... Closed photobioreactors are flexible systems that can be optimized according to the biological and physiological characteristics of the microalgal species involved. An overview of several closed or semiclosed culture systems used for mass cultivation of microalgae outdoors is presented in Figure 3.The simplest cultivation system is an illuminated bag containing the microalgal suspension, mixed ...

ORIGINAL PAPER A mini review: photobioreactors for large scale algal cultivation Prabuddha L. Gupta1 • Seung-Mok Lee1 • Hee-Jeong Choi1 Received: 26 April 2015/Accepted: 13 June 2015  · Microalgae cultivation has gained much interest in terms of the production of foods, biofuels, and bioactive compounds and offers a great potential option for cleaning the environment through CO2 sequestration and wastewater treatment. Although open pond cultivation is most affordable option, there tends to be insufficient control on growth conditions and the risk of contamination.

Photobioreactors for microalgae cultivation – An Overview M. K Egbo, A. O Okoani, I. E Okoh Abstract - One of the ways to combat global warming is to substitute the conventional fossil fuels that are used to meet most of the world energy demand with cheaper, cleaner, renewable and therefore sustainable energy (heat, electricity, and transport fuel) sources. Abstract The idea of internally illuminated photobioreactors has existed since the 1990s and various systems were developed since. Recently, the interest in these systems has been on the rise again...

 · Scale-up cultivation in a 10 L circular pond. A mini circular pond cultivation system was used to simulate the outdoor open pond cultivation under artificial illumination. The circular pond was equipped with four units to control mixing, irradiance, temperature, and pH, as described in … In all photobioreactors, chlorophyll a concentrations increased during the first 5–7 days, followed by a decrease to near zero . However, this was not seen with the other growth parameters (Figs 1 and 2A). Dissolved organic carbon (DOC) was released during the cultivation of C. vulgaris (Fig. 1E and F).

Microbial contamination during large-scale algal cultivation can significantly and consistently reduce biomass production. In this context, eukaryotic contaminants, such as amoebae, ciliates, and rotifers, and clusters of cells based on microscopy were found to cause biomass deterioration in P. falcata XJ-176 cultivation. The mini-review summarizes the designs of existing biofilm-based PBRs and reviews previous studies on DIC dynamics in various biofilms. ...
