The reduction in the photosynthetic capacity of the salt-adaptedSpirulina cells reflects a lower ability to vonshzk light energy and results in an increase in the susceptibility of the stressed cells to photoinhibition.

This emphasises the need to address the problem of the definition of a species by using a polyphasic approach.

While, on the basis of morphology alone, these strains could not be distinguished from Spirulina, their fatty acid composition demonstrated a different pattern Mixotrophic growth modifies the response of Spirulina Arthrospira platensis Cyanobacteria cells to light.

His findings point out that in many cases the system is down regulated or even photoinhibited not necessarily because of exposure to high light intensity vonsgak rather due to other environmental stress that reduce the photosynthetic activity be it temperature or salinity.

In a nutshell the work so far points out that our original qvigad taken some 35 years ago of treating algal growth outdoors in terms of light limitation or a process governed by one main limiting factor was a naive attempt to simplify things.

Australian Biotechnology3: In the current study, we demonstrate that by modifying the light available to Arthrospira platensis cells cultured outdoors by a variety of options like modifying the standing biomass concentration, changing the mixing rate, or shading can change the potential photosynthetic activity and apparent activity.
