Technological stress and the quality of spirulina biomass

Abstract

Arthrospira platensis is an industrially grown cyanobacterium in several countries, and its production is constantly increasing. Technological factors can be a useful tool for the quality of cyanobacterial biomass, but may present a risk of free radical accumulation. Taking into account that one of the requirements for technologies of cyanobacterial biomass production is to ensure the high quality of the final product, the purpose of this research was to investigate the influence of thermal, salt, illumination and chemical stresses on biomass quality of cyanobacterium Arthrospira platensis CNMN-CB-11 (spirulina).
