Microalgae is considered as sustainable and viable feedstock for biofuel production due to its significant advantages over terrestrial plants. Algal biofuels have received significant attention among researchers and energy experts owing to an upsurge in global energy issues emanating from depletion in fossil fuel reserves increasing greenhouse gases emission conflict among agricultural crops, traditional biomass feedstock, and potential futuristic energy security. Further, the exploration of value-added microalgae as sustainable and viable feedstock for the production of variety of biofuels such as biogas, bio-hydrogen, bioethanol, and biodiesel are addressed. Moreover, the assessment of life-cycle, energy balance, and environmental impacts of biofuel production from microalgae are briefly discussed. The present study focused on recent advancements in synthetic biology, metabolic engineering tools, algal bio refinery, and the optimization of algae growth conditions. This paper also elucidates the function of microalgae as bio refineries, the conditions of algae-based cultures, and other operational factors that must be adjusted to produce biofuels that are price-competitive with fossil fuels.
微藻被认为是生物燃料生产可持续且可行的原料，因为它比陆地植物具有显著优势。由于全球能源问题的加剧，包括化石燃料储备枯竭、温室气体排放增加、农业作物、传统生物质原料之间的冲突以及潜在的未来能源安全问题，藻类生物燃料受到了研究人员和能源专家的高度关注。此外，还探讨了利用增值微藻作为可持续且可行的原料来生产各种生物燃料，如沼气、生物氢、生物乙醇和生物柴油。此外，还简要讨论了微藻生物燃料生产的生命周期评估、能量平衡和环境影响。本研究侧重于合成生物学、代谢工程工具、藻类生物精炼厂和藻类生长条件优化方面的最新进展。本文还阐述了微藻作为生物精炼厂的功能、藻类培养的条件以及其他必须调整的操作因素，以生产具有价格竞争力的生物燃料，与化石燃料相媲美。
