       3.3.1.3 Micro and Macroalgal Biomass (Third-Generation - 3G)

      Microalgae belong to phytoplankton, a broad genus of plant and Photosynthetic organisms [49, 50]. The wastewater toxins can be removed easily by them. The processing of ethanol from microalgae biomass became a promising source that a decreased environmental effect, with an adequate fixation of CO2 and requiring less arable land [44] and generated bioethanol. Moncada et al. [51] were the first to combine molasses (first-generation feedstock) and microalgal biomass substrates (third-generation feedstock) for the production of ethanol (Table 3.3). This research suggested that sugarcane and microalgae integration appears to be profitable. Microwave-assisted heating wet torrefaction for acid pretreatment (Table 3.3) is a feasible green technology for microalgal biorefinery alternative to fossil fuel [41]. Another promising microalgae species, Golenkinia sp, accomplish microalgae-based renewable energy and wastewater treatment [42] (Table 3.3). For the commercial exploitation of microalgal-based biofuels, the use of all components of microalgal biomass is significant. Seaweeds and marine macroalgae contain high concentrations of starch and cellulose in their tissues. The viability of producing feedstock from seaweed (Ulva sp. (Chlorophyta)) in land-based cultivation has potential in terms of bioethanol [46]. Freshwater macroalgae feedstocks are potential for bioenergy generation (Table 3.3). The presence of lipid content of 18.6% in macroalgae biomass suggests that freshwater macroalgae are a possible biodiesel source [47].
