“…These photosynthetic organisms simply require a source of nitrogen, phosphorus, sulfur, potassium, and iron to lock CO 2 into biomass at a higher efficiency than land plants (Chen et al 2020 ; Markou et al 2014 ; Muzzopappa and Kirilovsky 2020 ). Cyanobacteria and microalgae can be cultivated using nutrient containing wastewater which saves fertilizers and water to a greater extent (Luo et al 2019 ; Rajneesh et al 2017 ; Tan et al 2020 ; Zhu et al 2017 ). Thus, cyanobacterial and microalgal cultivation does not essentially require fertile land.…”

The total number of inhabitants on the Earth is estimated to cross a record number of 9 × 10 3 million by 2050 that present a unique challenge to provide energy and clean environment to every individual. The growth in population results in a change of land use, and greenhouse gas emission due to increased industrialization and transportation. Energy consumption affects the quality of the environment by adding carbon dioxide and other pollutants to the atmosphere. This leads to oceanic acidification and other environmental fluctuations due to global climate change. Concurrently, speedy utilization of known conventional fuel reservoirs causes a challenge to a sustainable supply of energy. Therefore, an alternate energy resource is required that can maintain the sustainability of energy and environment. Among different alternatives, energy production from high carbon dioxide capturing photosynthetic aquatic microbes is an emerging technology to clean environment and produce carbon-neutral energy from their hydrocarbon-rich biomass. However, economical challenges due to low biomass production still prevent the commercialization of bioenergy. In this work, we review the impact of fossil fuels burning, which is predominantly used to fulfill global energy demand, on the quality of the environment. We also assess the status of biofuel production and utilization and discuss its potential to clean the environment. The complications associated with biofuel manufacturing using photosynthetic microorganisms are discussed and directed evolution for targeted phenotypes and targeted delivery of nutrients are proposed as potential strategies to increase the biomass production.

The increasing demand for fossil fuels and the climate change caused by burning those fuels have become serious global problems. Worldwide, countries have begun to implement energy strategies that include the development of renewable energy sources (Chen, Hu, et al., 2015; Chen, Qiu, et al., 2015). As the only energy source that can be used directly to produce fuels for transportation, biofuels are favored among the renewable energy sources available (e.g., biomass, solar, wind, geothermal, and tidal energy). In particular, microalgae represent a promising feedstock for biofuel production (Chen, Hu, et al., 2015; Chen, Qiu, et al., 2015). Photosynthesis of higher plants and microalgae plays critical roles in important physiological processes, such as lipids, sugars, and proteins biosynthesis (Ouyang et al., 2020; Zheng, Xue, Chen, He, & Wang, 2020). Microalgae are unicellular photosynthetic microorganisms that are used as sources of carbohydrates, pigments, food supplements, fertilizers, and biofuels (Fierro, Sánchez-Saavedra, & Copalcúa, 2008; Hemaiswarya, Raja, Kumar, Ganesan, & Anbazhagan, 2011). Due to their widespread availability and higher oil yields than conventional terrestrial plants (Lv, Cheng, Xu, Zhang, & Chen, 2010), microalgae have been investigated as a feedstock for biodiesel production since the 1970s (Zhan, Rong, & Wang, 2017). Microalgae grow more rapidly than plants and can be grown in non-arable lands

“…High removal efficiency of nutrients is expected in the algae‐based wastewater remediation to ensure that the effluent can meet the requirements of current regulations. Up to now, it has been proven that a variety of agriculture‐related wastewater, such as animal manure, food processing effluent, aquaculture wastewater, can be treated by the algae 7,19,20 . As shown in Table 1, algae, including microalgae and cyanobacteria, could effectively remove a portion of nutrients in wastewater, and at the same time, produce biomass.…”

Soil degradation, overuse of chemical fertilizer, and biodiversity loss are serious problems challenging the sustainable development of modern agriculture. In recent years, owing to the advantages of algae biotechnology in nutrients recovery and soil improvement, the integration of algae‐based wastewater remediation and algal bio‐fertilizer production is emerging into the limelight. In this work, we emphasize on the progresses achieved in the fields of biomass production by algae cultivation in wastewater and application of algal bio‐fertilizers. Particularly, three types of algal bio‐fertilizers, including slow‐release bio‐fertilizer, nitrogen‐fixing cyanobacteria, and liquid bio‐fertilizer, widely evaluated and utilized in agriculture are introduced. To prevent the overly optimistic prediction of algal bio‐fertilizer in a real‐world application, we point out the challenges and technical defects, such as presence of new pollution factors in wastewater, high cost of algal biomass, contamination of algal biomass in wastewater, low productivity of algae and valuable components, high water consumption, and potential threats of cyanobacteria to the environment, that prevent the concept of integrating algae‐based wastewater remediation and algal bio‐fertilizer production from becoming a reality. Based on our knowledge and experience, potential solutions to the aforementioned problems are discussed in depth. It is expected that the emerging technologies of algae‐based wastewater remediation for bio‐fertilizer production will bring human beings into a new era of environmentally‐friendly, high‐yield, and resource‐recycling agriculture. © 2020 Society of Chemical Industry (SCI)
