“…The better perfomance of such a system with respect to open ponds has already been demonstrated. 7 In addition, vertical column reactors are compact, lowcost and easy to operate monoseptically. 10 Thus vertical columns are a realistic option for producing large quantities of microalgal biomass.…”

International audienceBACKROUND: Spirulina platensis (Toliara, Madagascar) provides a food supplement which can fight against malnutrition and food insufficiency in Madagascar. In this country, the current production from three open basins is not sufficient to cover needs, and presents drawbacks such as low productivity and possible contamination. Thus cultivation of S. platensis in a closed photobioreactor opens the possibility of extending this microalga production. In this study, the influence of colour and intensity of the light on S. platensis growth and protein content was investigated in a bubble column.RESULTS: Growth kinetics were obtained for four colours (green, white, red and blue) and four intensities (400, 800, 1000 and 1200 lux) of light. The influence of light colour on Spirulina growth was discussed. The highest productivity (183.6mg L(-1) d(-1)) and concentration (2643mg L(-1)) were obtained for green light at 1200 lux. The protein content was 58%.CONCLUSION: Using green light allows improvement of S. platensis growth. Performance obtained with the closed system was higher than that reported in the literature

“…5 However such systems do not lead to high biomass concentration. 6,7 The main reasons are variability of temperature, susceptibility to contamination and low efficiency of light penetration due to low surface/volume ratio. 8 The use of a closed system could reduce these disavantages and increase productivity and cell concentration.…”

“…The pH of the culture medium was controlled at 9.5 ± 0.2 by daily addition of CO 2 from a cylinder. 10 Continuous light intensity was regulated at 10 klux, corresponding to 120 µmol photons m −2 s −1 , by fluorescent lamps and an illuminance meter, model LI-250A (LICOR, Lincoln, NE). 22 Temperature was regulated at the selected values by means of resistances submerged in the cultivation medium.…”

Kinetic and thermodynamic investigation of Arthrospira (Spirulina) platensis fed-batch cultivation in a tubular photobioreactor using urea as nitrogen source JOURNAL OF CHEMICAL TECHNOLOGY AND BIOTECHNOLOGY, HOBOKEN, v. 87, n. 11, pp. 1574-1583, NOV, 2012 BACKGROUND: Fed-batch culture allows the cultivation of Arthrospira platensis using urea as nitrogen source. Tubular photobioreactors substantially increase cell growth, but the successful use of this cheap nitrogen source requires a knowledge of the kinetic and thermodynamic parameters of the process. This work aims at identifying the effect of two independent variables, temperature (T) and urea daily molar flow-rate (U), on cell growth, biomass composition and thermodynamic parameters involved in this photosynthetic cultivation.

“…Commercial large-scale culturing and harvesting of Spirulina commenced in the early 1970s in Lake Texcoco, Mexico by Sosa Texcoco S.A. [18]. Microalgae cultivation is still of great interest among consumers due to Spirulina properties [25]. Currently, the production of microalgal biomass reaches 5 000 tonnes of dry matter every year, it is mostly produced in open ponds.…”

“…The outdoor cultures allow to obtain large amounts of biomass at low costs. This system does not require control of the environmental conditions (light and temperature) [25]. Among the open systems, the natural waters (lakes, lagoons, ponds) and artificial ponds or containers can be mentioned [33].…”

Prospects of geothermal water Use in cultivation of Spirulina

et al. 2015

Spirulina has been studied due to its commercial importance as a source of essential amino acids, protein, vitamins, fatty acids etc. Most of the culture systems in use today are open ponds. The new approach proposed in this paper is to use the geothermal water as a medium for microalgae cultivation. Poland has beneficial conditions for wide geothermal use, as one of the environmentally friendly and sustainable renewable energy sources. In the planned research, geothermal water could be used to prepare microalgal culture medium, to heat greenhouses with bioreactors used for the growth of Spirulina, to dry the obtained biomass, as well as to heat the ground in foil tunnels. Using geothermal water gives the possibility to produce algae in open ponds covered with greenhouses and to cultivate plants during winter. The obtained algae can be used for the production of algal bio-products (e.g. homogenates), having the potential application in plant cultivation.
