Methods for Estimation of Oxidative Stress Indices in Cyanobacteria

Abstract

Cyanobacteria are a primitive group of photosynthetic microorganisms that perform oxygenic photosynthesis in the presence of sunlight. These prokaryotes have emerged as model organisms in the last decade for the production of bioenergy and industrially important chemicals in a carbon-neutral manner (Pathak et al. 2018; Rajneesh et al. 2017). Cyanobacteria are also good sources of natural antioxidants that are produced as a protective mechanism against toxic reactive oxygen species (ROS) (Jerez-Martel et al. 2017; Guerreiro et al. 2020). Due to their photoautotrophic mode of nutrition, cyanobacteria experience seasonal and diurnal changes in quality and quantity of light, temperature, nutrient availability, CO2 levels, salinity and pH (Singh and Montgomery 2013; Kumar et al. 2021). © 2024 selection and editorial matter, Shailendra P.
