Evaluation of three Spirulina species grown under similar conditions for their growth and biochemicals

Abstract

Growth pattern and biochemical composition of three species of Spirulina, S platensis, S laxissima and S lonar, were studied under controlled culture conditions. The chemical constituents were analysed in terms of chlorophyll-a, phycobilliproteins, β-carotene and phenolics (intracellular and extracellular). Of the three species S platensis showed highest growth rate, biomass, pigment concentration and low intracellular phenolics. The shortest doubling time was seen in S platensis. The results demonstrated the importance of strain selection for large-scale cultivation. The results also showed differences in culture conditions (light intensity and pH) for the three species of Spirulina to obtain the maximum growth, as well as biochemical basis for obtaining the maximum growth in Spirulina spp.

Cultivation of Acidophilic Algae Galdieria sulphuraria and Pseudochlorella sp. YKT1 in Media Derived from Acidic Hot Springs

“…In this study, the phycocyanin contents in G. sulphuraria cultured in spring water media were 84.12 ± 3.93 μg/mg dry weight in Ta + NH 4 + and 107.42 ± 1.81 μg/mg dry weight in Tsu + NH 4 + ( Figure 3F ). These are relatively lower than but still comparable to the level reported in the Spirulina platensis (148.3 μg/mg dry weight) is currently used in the phycocyanin produced for commercial use (Bhattacharya and Shivaprakash, 2005). At present, the application of phycocyanin is limited because of its sensitivity to temperature and pH (Sarada et al, 1999).…”

Effect of Gamma Radiation on Growth and Metabolic Activities of Arthrospira platensis

“…platensis growth was monitored using the optical density of the culture at 750 nm (OD750) and by the determination of cellular dry weight (CDW) according to Bhattacharya and Shivaprakash (2005).…”

High yield preparation of purpurin-18 from Spirulina maxima

“…An experiment taking into account this optimized combination of factors gave 31.5 mg of Pp-18 (0.63% of initial spirulina mass) (about three times more than previously observed yields). Since S. maxima contains about 1% of chlorophyll a [10], and given the molecular weights of chlorophyll a and Pp-18 (893.5 and 564.6 respectively), this yield corresponds to an essentially quantitative conversion of chlorophyll a into Pp-18. …”
