Multilateral Approach on Enhancing Economic Viability of Lipid Production from Microalgae: A Review

Shin, Ye Sol, Choi, Hong Il, Choi, Jin Won, Lee, Jeong Seop, Sung, Young Joon, Sim, Sang Jun·2018·Bioresource Technology

Abstract

Microalgae have been rising as a feedstock for biofuel in response to the energy crisis. Due to a high lipid content, composed of fatty acids favorable for the biodiesel production, microalgae are still being investigated as an alternative to biodiesel. Environmental factors and process conditions can alternate the quality and the quantity of lipid produced by microalgae, which can be critical for the overall production of biodiesel. To maximize both the lipid content and the biomass productivity, it is necessary to start with robust algal strains and optimal physio-chemical properties of the culture environment in combination with a novel culture system. These accumulative approaches for cost reduction can take algal process one step closer in achieving the economic feasibility.

  • Certain microalgae species have been discovered thriving in elevated CO2 environments, with a few demonstrating enhanced lipid accumulation capabilities even under a 15% CO2 culture condition.

    “Currently, certain microalgae species have been discovered thriving in elevated CO2 environments, with a few demonstrating enhanced lipid accumulation capabilities even under a 15% CO2 culture condition [91–95].”
  • Chlorophyll and proteins are degraded as a nitrogen source to support photosynthesis with nitrogen limitation, and the excess carbon is used to synthesize fatty acids, which is also the reason for the changes in fatty acid composition of microalgae under nitrogen deficiency.

    “According to this view, the chlorophyll and proteins are degraded as a nitrogen source to support photosynthesis with nitrogen limitation, and the excess carbon is used to the synthesize FAs, which is also the reason for the changes in FAs composition of microalgae under nitrogen deficiency [94].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
