Evaluation of Growth Yield of Spirulina maxima in Photobioreactors

Abstract

The paper deals with the evaluation of the parameters for the cultivation of Spirulina maxima in two reactors (large-laboratory scale (LL) and semi-technical scale (ST)), whose illuminated areas in respect of the illuminated volume are different, and with the operating costs. We evaluated the growth yield coefficients for Spirulina maxima cultures. In the LL, the following factors were identified: Y O 2 /X -65.5; Y X/CO 2 -0.0806; Y X/P 2 O 5 -0.0082, while in the ST: Y O 2 /X -583; Y X/CO 2 -0.017; Y X/P 2 O 5 -0.0023. Although the reactor in the ST was equipped with many devices that should have improved the efficiency of cultivation, the obtained result was lower compared to the culture conducted in the LL. It was proved that it was possible to perform the cultivation of Spirulina maxima under temperate climate conditions in simply constructed, low cost reactors.

Combination of nejayote and swine wastewater as a medium for Arthrospira maxima and Chlorella vulgaris production and wastewater treatment

“…Moreover, our growth kinetic showed similar as to the growth of A. platensis grown in modified Zarrouk's, Hiri's and Jourdan's media (Delrue et al, 2017;Mishra and Prasad, 2015). Additionally, the growth rate (μ max = 0.30) obtained was higher, than reported by Saeid and collaborators (μ max = 0.19) (Saeid, 2016). On the other hand, C. vulgaris reached a concentration greater than 100 × 10 6 cell/mL, around day 15 (Fig.…”

Tendencies Affecting the Growth and Cultivation of Genus Spirulina: An Investigative Review on Current Trends

“…The pond was covered with a polyethylene sheet that was 0.2 mm-thick, which resulted in a temperature rise in the culture medium that was 5-7 • C higher than the temperature of the pond while it was open. This temperature increase had an effect on the culture [54]. Thus, the temperature is one of the most important environmental factors that can influence the rate at which spirulina grows.…”

“…The reason for this was because at this wavelength, the interference from chlorophyll pigment was at its lowest [15,52]. Madkour et al [17] and Saeid and Chojnacka [54] measured the concentration of spirulina biomass in the cultivation media every three days by measuring the optical density at 560 nm. They also measured the concentration of the biomass of Spirulina spp.…”

Pengaruh Salinitas terhadap Kepadatan Populasi dan Konsentrasi Klorofil-a Spirulina pada Media Kultur Modifikasi Walne dan Air Limbah Budidaya Ikan

“…Sebelum dilakukan kultur, bibit Spirulina dari kultur murni terlebih dahulu dilakukan perhitungan kepadatan sel jumlah awal inokulan yang akan dikultur menggunakan spektrofotometer pada panjang gelombang 560 nm (Saeid & Chojnacka, 2016). Kultivasi dilakukan digelas erlenmeyer dengan volume media kultur sebanyak 500 mL, dengan volume bibit Spirulina 25 mL, kemudian ditambahkan walne dan air limbah budidaya ikan sebanyak 0,5 mL (1:1), vitamin B1 dan B12 masingmasing 0,2 mL.…”
