when there's a development of harmful algal blooms which produce toxins such as microcystin, anatoxin, saxitoxin which hamper the ecosystem and due to algaecide treatment these toxins are released in the environment and kill many aquatic organisms I want to check what will happen when both toxins and algaecide are exposed to microalgae. Due to eutrophication there's variation in abiotic factors such as light, temperature, nutrients level, Ph etc I want to know the combined effect of these stressors on microalgae used in wastewater treatment.
I am research scholar interested to work on this aspect. Your suggestions will be very much helpful for me to pursue my research work.
Thank you.

When eukaryotic microalgae are exposed to different abiotic and biotic stresses simultaneously, their physiological and biochemical responses can be complex and varied. These stresses can include environmental factors (abiotic) such as temperature changes, light intensity, pH fluctuations, salinity variations, nutrient limitations, and oxidative stress, as well as biological factors (biotic) such as competition with other microorganisms, allelopathy, and predation.
The specific responses of microalgae will depend on various factors, including the species of microalgae, the intensity and duration of the stresses, and the availability of resources. Here are some possible outcomes and responses when microalgae face combined abiotic and biotic stresses:
It is essential to note that the response of eukaryotic microalgae to combined stresses is highly diverse and specific to each species. Additionally, some microalgae are more resilient and adaptable to multiple stressors, while others may be more sensitive, leading to potential shifts in microalgal community composition and ecological dynamics in aquatic ecosystems. Understanding these responses is crucial for studying the impacts of environmental changes on microalgal populations and ecosystem functioning.
