A mnode-locked laser was used to measure fluorescence decay down to 80 picoseconds. Measurements on the fluorescence of methylene blue quenchled with potassium iodide demonstrate the effectiveness of the method. Fluorescence decay times of chlorophyll b (3.87 +/- 0.05 nianoseconds) and c-phycocyanin (1.14 +/- 0.01 nanoseconds) in vitro and chlorophyll a in the green alga Chlorella pyrenoidosa (...

More than 20 Synechococcus and Cyanobium isolates were obtained from central European subalpine lakes and sequenced for their 16S rRNA gene and part of the phycocyanin operon (cpc), specifically the intergenic spacer (IGS) between cpcB and cpcA, and corresponding flanking regions (cpcBA-IGS). Maximum-likelihood analyses revealed the existence of at least six to seven clusters of nonmarine picoc...

Abstract The integration of semi‐transparent photovoltaics (PVs) with photobioreactors (PBRs) is a promising strategy to increase photoconversion efficiency, ensuring simultaneous electricity and algal biomass production. In this study, Arthrospira maxima cultivated in an integrated system dye‐sensitized solar module (DSSM) the front PBR assess possible advantages for phycocyanin application DS...

Research into the extraction of phycobiliprotein from Arthrospira platensis is currently ongoing. Most traditional methods include use organic solvents, which negatively affect sustainability process. Ionic liquids (ILs) are a promising alternative for due to their properties as green solvents. In present work an imidazolium-based IL and sonication were studied carbohydrate extraction. A factor...

Spirulina platensis can synthesize a large amount of phycocyanin, which had been developed as health food. At the same time, absorb nitrogen and phosphorus in wastewater provide for its own growth. Here, we studied optimal supply production process. For first 405 nm portable Raman spectrometer was used to estimate phycocyanin content real-time industrial applications. We obtained three characte...

We have identified the function of the 'extra' polypeptides involved in phycobilisome assembly in Nostoc sp. These phycobilisomes, as those of other cyanobacteria, are composed of an allophycocyanin core, phycoerythrinand phycocyanin-containing rods, and five additional polypeptides of 95, 34.5, 34, 32, and 29 kilodaltons. The 95 kilodalton polypeptide anchors the phycobilisome to the thylakoid...
