Nanobiotechnology of photosynthetic microorganisms for sustainable development: controlled oxidative stress and metabolic responses

Abstract

Interactions between engineered nanoparticles (NPs) and photosynthetic microorganisms represent a rapidly developing field at the interface of nanotechnology and microbial biotechnology. Metal and metal oxide nanoparticles can act as both stressors and modulators of cellular metabolism, inducing oxidative stress responses that may lead to either growth inhibition or adaptive metabolic redirection. Aim of the study: The study aims to elucidate the physiological and biochemical responses of selected photosynthetic microorganisms (cyanobacteria and microalgae) to exposure to engineered nanoparticles, with a focus on oxidative stress modulation and its impact on biomass productivity and metabolite accumulation.
