“…Between the different light conditions, the highest phycocyanin content was obtained under LL, followed by NL, while HL gave significantly lower values. These results are in agreement with previous observations that both a reduction in the light quantity and change in light quality (light spectrum towards red) can induce an increase in the phycocyanin concentration in Arthrospira biomass. This observation can be explained by the capacity of chromatic adaptation of many cyanobacteria, including Arthrospira , in which cyanobacteria adjust their pigment composition in response to light alterations .…”

BACKGROUND The cyanobacterium Arthrospira contains proteins and the blue pigment phycocyanin that can be used as a natural colourant in the food industry. The aim of this study was to investigate a strategy for increasing the yield of phycocyanin and protein from Arthrospira cultures by shading the cultures with neutral density and red light filters. Experiments were conducted under three different irradiance conditions: (i) laboratory tests under relatively low light intensities (100 μmol m−2 s−1), (ii) laboratory tests under relatively high light intensities (516 μmol m−2 s−1) and (iii) scaled‐up tests under natural conditions by cultivating Arthrospira in raceway ponds in a greenhouse. RESULTS In all cases, shading of cultures with red filters resulted in biomass with increased phycocyanin content achieving a maximum of 134, 71 and 121 mg g−1 under low light intensity, high light intensity and natural conditions, respectively. Under high light intensity and natural conditions, shaded cultures displayed phycocyanin of higher purity and increased protein content, which reached up to 43 and 65%, respectively. CONCLUSIONS Shading of Arthrospira cultures by low‐cost polyester red light filters may be an effective way for enhancing phycocyanin production and improving its purity in outdoor ‘spirulina farms’. © 2019 Society of Chemical Industry

“…depending on the growth conditions (e.g. light, temperature and nitrogen availability) (Chen et al 2013;Ho et al, 2018;Lima et al, 2018;Pagels et al, 2019). In comparison, the highest reported productivity for a thermostable PC from cyanobacteria is much lower (ca.…”

“…Improving the productivity of PBPs from thermophilic species could be achieved by optimising growth conditions and media composition (del Rio-Chanona et al, 2015;Lima et al, 2018;Mogany et al, 2018 (Mancini et al, 2017;Sheehan et al, 2018;Dawson et al, 2019). An increasing availability of synthetic biology tools in cyanobacteria could help to further increase PBP production as well as understand PBS stability properties (Gale et al, 2019;Vasudevan et al, 2019).…”

The light-harvesting phycobilisome complex is an important component of photosynthesis in cyanobacteria and red algae. Phycobilisomes are composed of phycobiliproteins, including the blue phycobiliprotein phycocyanin, that are considered high-value products with applications in several industries. Remarkably, several cyanobacteria and red algal species retain the capacity to harvest light and photosynthesise under highly selective environments such as hot springs, and flourish in extremes of pH and elevated temperatures. These thermophilic organisms produce thermostable phycobiliproteins, which have superior qualities much needed for wider adoption of these natural pigment–proteins in the food, textile, and other industries. Here we review the available literature on the thermostability of phycobilisome components from thermophilic species and discuss how a better appreciation of phycobiliproteins from extreme environments will benefit our fundamental understanding of photosynthetic adaptation and could provide a sustainable resource for several industrial processes.

“…Arthrospira species are valued due to their rich composition of minerals and antioxidants, and high protein content and essential amino acids. Additionally, Arthrospira biomass can be used for the extraction of high-value products, such as pigments, including chlorophyll a, beta-carotene and phycocyanin (Lima et al, 2018). Pigment production using cyanobacteria offers advantages over its production from other sources like higher plants, as cyanobacteria have faster growth rates and high photosynthesis efficiencies and also require less space (Khazi et al, 2018).…”

A two-phase outdoor cultivation bioprocess for Arthrospira maxima LJGR1 combined with phycocyanin induction in concentrated cultures under controlled conditions, was evaluated using a modified low-cost Zarrouk medium. Growth was monitored during 4 cycles in 2018 and 4 cycles in 2019. Biomass was harvested and concentrated using membrane technology at the end of each cycle for further phycocyanin induction using blue LED light (controlled conditions, 24h). The highest biomass productivity was observed during spring and summer cycles; during mid-fall and mid-end fall, a decrease was observed.Under favorable growth conditions, phycocyanin induction was successful.However, during cycles with unfavorable growth condition, phycocyanin induction was not observed. Reagent grade phycocyanin was recovered and purified using microfiltration and ultrafiltration technologies. It was concluded that this novel two phase process has a potential to be implemented at larger scale within a biorefinery approach including the production of sub products from residual biomass and exopolysaccharides.
