Microalgal Biotechnology Application Towards Environmental Sustainability

Many researches have been conducted to investigate the alternative source of energy from renewable sources and utilization of waste materials. Among which, microalgae, having wide range of environmental adaptability, represents a diverse group of microorganisms; hence, its application in biotechnology is among the scholars’ interest. Microalgae have the ability to store lipids and preserve the nutrients presented in the wastewater, which help in wastewater treatments. Besides, the algal biofuel production gained research interest in recent years. Among few important factors for the microalgal growth, proper presence of light and sufficient nutrients such as nitrogen and phosphorus are essential. Developing algae production would help to mitigate greenhouse gas emissions by capturing CO2, and producing an alternative option for fossil fuels which could be valuable and sustainable. Hence, with growing interest and several analyses, this review discusses the key points in developing microalgal biotechnology toward sustainable development.
