The need to develop new concepts in reactor design and the growing interest inSpirulina prompted our group to abandon open ponds in the seventies and to focus interest mainly on closed systems. Two substantially different closed photobioreactors have been developed and are at present under investigation in our Research Centre: the tubular photobioreactor (made of rigid or collapsible tubes) and the recently devised vertical alveolar panel (VAP) made of 1.6-cm-thick Plexiglas alveolar sheets.The…

As integrated culture system for outdoor production of microalgae and cyanobacteria
The productivity obtained in the integrated system was higher than the sum of the productivities of the pond and panel systems operating separately, and a near-optimum temperature regimen for Arthrospira platensis was maintained.
Microalgal Reactors: A Review of Enclosed System Designs and Performances
Several types of closed bioreactors described in the technical literature as able to support production of microalgae are comprehensively presented and duly discussed, using transport phenomenon and process engineering methodological approaches.
Productivity and photosynthetic efficiency of outdoor cultures of Tetraselmis suecica in annular columns
The mass transfer at different aeration rates and the influence of the harvest rate on productivity and biochemical composition were investigated and the potential of the system was evaluated by estimating productivity at full-scale.
Microalgal Production Systems with Highlights of Bioenergy Production
The purpose of this chapter is to provide an overview of the main systems of microalgae production with highlights of biofuel production. The large-scale production systems (raceway ponds, horizontal
Novel simulation model of the solar collector of BIOCOIL photobioreactors for CO2 sequestration with microalgae
Abstract A novel mathematical model to simulate the growth of microalgae in the solar collector of recirculating helical photobioreactors (BIOCOIL) is proposed. The dynamic-spatial behavior of the
Biotechnology of algal biomass production: a review of systems for outdoor mass culture
The present review surveys advances in closed and open technologies for cultivation of microalgae and the advantages and disadvantages of open systems and closed photobioreactors are discussed.
Open Pond Culture Systems and Photobioreactors for Microalgal Biofuel Production
Microalgal biomass offers sustainable and carbon-efficient alternative for biofuel production. Biofuels from microalgae feature considerable potential to meet future challenges of carbon
Use of photoacclimation in the design of a novel photobioreactor to achieve high yields in algal mass cultivation
In the continuous flow photobioreactor described here, algal cells acclimated to different light conditions together permit utilization of the entire light gradient found in an optically dense medium, such as in a high-density culture.
Comparative analysis of the outdoor culture of Haematococcus pluvialis in tubular and bubble column photobioreactors.
It is concluded that the methodology developed in the present study allows the monitoring of H. pluvialis cultures characterized by fast variations of cell morphology and biochemical composition, especially in outdoor conditions, and that tubular photobioreactors are preferable to bubble columns for the production of biomass and/or astaxanthin.
Saline microalgae for biofuels: Outdoor culture from small-scale to pilot scale
The feasibility of outdoor large scale cultivation of the halophilic Tetraselmis strains Mur-230 and MUR-233 with a high potential as feedstock for biofuel and carbon dioxide mitigation is demonstrated.


A closed system for outdoor cultivation of Porphyridium
It seems that polyethylene sleeves have the following advantages over open ponds: high light availability, high rate of heating and cooling, improved turbulence, relative lack of contamination, and prevention of evaporation and hence of fluctuation in salinity.
Production of Spirulina biomass in closed photobioreactors
The results of a six year investigation on the outdoor mass culture of Spirulina platensis and S. maxima in closed tubular photobioreactors are reported and the main problems encountered relate to the control of temperature and oxygen concentration in the culture suspension.
Vertical tubular reactor for microalgae cultivation
SummaryVertical glass tubular reactors, 5 cm in diameter and 2.35 m high, were used to grow several species of cyanobacteria, green algae, and diatoms. The reactors were gassed with an air/CO2
A vertical alveolar panel (VAP) for outdoor mass cultivation of microalgae and cyanobacteria
A vertical alveolar panel (VAP) for microalgal mass cultivation has been devised and developed. VAP reactors with a surface area of 0·5−2·2 m2 were constructed from Plexiglas alveolar sheets 1·6 cm
Photobioreactor design: Mixing, carbon utilization, and oxygen accumulation
For most products of algal mass cultivation, open ponds are the only feasible photobioreactor design capable of meeting the economic and operating requirements of such systems, provided desirable species can be maintained.
Enclosed bioreactors for the mass cultivation of photosynthetic microorganisms: the future trend
In order that algal biotechnology can be upgraded to the current level of bacterial and fungal biotechnologies, the adoption of fully controllable, enclosed fermentation systems is a prerequisite.
Quantitative assessment of the major limitations on productivity ofSpirulina platensis in open raceways
