Furthermore, the lack of advanced models or algorithms for process designing and limited genetic and molecular knowledge is a key bottleneck. However, the major bottleneck in biorefinery includes (i) low biomass and biomolecules production, (ii) high cost, (iii) less economic viability, (iv) high energy requirement, and (v) environmental impacts of the process. Moreover, its commercialization can enable a jump start towards resolving energy and economic crisis.
Microalgae (MA) biorefinery is a vital platform for the conversion of biomass into biofuels, biomaterials, and bioactive substances and it can remediate the pollutant from the environment.
#Sequential biofuels serial#
The proposed serial fermentation process would maximize the utilization of biomasses for biofuel production, with minimum leftover (11%). Successive fermentations served as a bio-pretreatment to enhance the bioavailability of the leftover protein and lipid, which minimized the use of expensive and laborious methods for their extraction from the microalgal biomass. Lipid was the dominant component after the previous fermentation, which was converted to biodiesel via transesterification process. Serial fermentations were implemented for thorough utilization of the biomass constituents, starting with carbohydrate, followed by protein to derive ethanol (C2) and higher alcohols (C3–C5), respectively.
This process provided a platform for maximum recovery of energy carriers from biomass utilization (89%). A successive high-throughput fermentation followed by transesterification were employed. Herein, we introduce a novel integrated approach to achieve unprecedented energy conversion efficiency (46%) of microalgalīiomass (Chlamydomonas mexicana). However, the energy efficiency of microalgal pretreatment and conversion technologies needs to be improved to meet the economic viability.
Microalgae represent a promising feedstock for biofuel production.
