Are cyanobacteria a nearly immortal source of high market value compounds?

BACKGROUND When the human population increases, so does need to explore a wider range of feedstocks and biomasses, such as cyanobacteria. However, deeper understanding growth patterns pigment production is required support selection most beneficial species conditions for industrial production. The (i.e., chlorophyll C-phycocyanin) three cyanobacterium were evaluated following three-fold aim. first goal was compare among commonly selected exploitation (Arthrospira platensis) two alternative (Anabaena cylindrica Nostoc muscorum). second analyzing in long-term. last involved comparing different methods (spectrophotometry fluorimetry) understand whether there an appropriate proxy biomass increase that can be used monitoring purposes. RESULTS All showed high longevity proved capable growing more than 100 days without any additional supplementation. maximum quantum yield PS II (Fv /Fm ) revealed their photosynthetic efficiency varied over time with clear decrease after 2 months. Pigment analysis heterogeneous pattern during periods all could only captured by parameter Fv /Fm, but present A. N. muscorum some stages culture period. CONCLUSION found best C-phycocyanin producer, peaking at defined within profile. © 2022 Authors.
