Estimation of Growth and Photosynthetic Pigments in Cyanobacteria

Abstract

The first oxygenic photosynthesis on the Earth was performed by cyanobacteria during the Precambrian period. These Gram-negative bacteria are cosmopolitan in distribution and play an important role in any ecosystem because of their inherent ability to fix carbon dioxide and dinitrogen (Bryant 1994). Due to their photoautotrophic mode of nutrition, cyanobacteria have an obligatory requirement for the harvesting of solar radiation to produce adenosine triphosphate (ATP) and NADPH2. © 2024 selection and editorial matter, Shailendra P.
