Abstract The world is experiencing an energy crisis and environmental issues due to the depletion of fossil fuels continuous increase in carbon dioxide concentrations. Microalgal biofuels are produced using sunlight, water, simple salt minerals. Their high growth rate, photosynthesis, sequestration capacity make them one most important biorefinery platforms. Furthermore, microalgae's ability alter their metabolism response stresses produce relatively levels high-value compounds makes a promising alternative fuels. As result, microalgae can significantly contribute long-term solutions critical global such as climate change. benefits algal biofuel have been demonstrated by significant reductions dioxide, nitrogen oxide, sulfur oxide emissions. Microalgae-derived biomass has potential generate wide range commercially compounds, novel materials, feedstock for variety industries, including cosmetics, food, feed. This review evaluates microalgal bioenergy carriers, biodiesel from stored lipids, alcohols reserved carbohydrate fermentation, hydrogen, syngas, methane, biochar bio-oils via anaerobic digestion, pyrolysis, gasification. use routes atmospheric removal approach being evaluated. cost production primarily determined culturing (77%), harvesting (12%), lipid extraction (7.9%). choice species cultivation mode (autotrophic, heterotrophic, mixotrophic) factors controlling production, well fuel properties. simultaneous agricultural, municipal, or industrial wastewater low-cost option that could reduce economic costs while also providing valuable remediation service. Microalgae proposed viable candidate capture atmosphere point source. sequester 1.3 kg 1 biomass. Using potent strains efficient design bioreactors thus challenge. theoretically up 9% light convert 513 tons into 280 dry per hectare year open closed cultures. integrated bio-refinery recover high-value-added products waste create processing bioenergy. To system, should be coupled with thermochemical technologies, pyrolysis.

Carbohydrates or polysaccharides are the main products derived from photosynthesis and carbon fixation in Calvin cycle. Compared to other sources, microalgae safe, biocompatible, biodegradable, stable, versatile. These polymeric macromolecules present complex biochemical structures according each microalgal species. In addition, they exhibit emulsifying properties biological characteristics that include antioxidant, anti-inflammatory, antitumor, antimicrobial activities. Some species have a naturally high concentration of carbohydrates. Other can adapt their metabolism produce more sugars changes temperature light, source, macro micronutrient limitations (mainly nitrogen), saline stress. addition growing adverse conditions, use industrial effluents as an alternative source nutrients. Microalgal predominantly composed pentose hexose monosaccharide subunits with many glycosidic bonds. Microalgae be structural constituents cell wall, energy stores, protective interaction. The is on rise. microorganisms rheological properties, making them promising candidate for application food industry agriculture. Thus, sustainable alternatives potential applications several sectors, choice producing depends required functional activity. this context, review article aims provide overview technology polysaccharide production, emphasizing its food, animal feed, agriculture sector.

The development of biohydrogen as an alternative energy source has had great economic and environmental benefits. Hydrogen production from microalgae is considered a clean sustainable method that can both alleviate fuel shortages recycle waste. Although algal hydrogen low consumption requires only simple pretreatment, it not been commercialized because product yields. To increase microalgal several technologies have developed, although they struggle with the oxygen sensitivity hydrogenases responsible for complexity metabolic network. In this review, genetic engineering studies on enhancing are discussed, feasibility future direction commercialization also proposed.
