A Mini Review of Biochemical Conversion of Algal Biorefinery
Abstract
Algal biomass is rich in essential components such as proteins, carbohydrates, and lipids, which are considered as a potential feedstock for algae-based fuel and chemical production. The commercial application of algae-based fuel production is a challenging task because algal cultivation and harvesting demand high energy and cost. It is a common bottleneck problem in algae processed for fuel or chemical production at the pilot scale. The execution of the concept of integrated algal biorefinery has the possibility to reduce the demand for energy and costs. It is comparatively economical to conventional methods in terms of the recovery of various value-added bioproducts including biopolymers, biochemicals, biofertilizers, and biofuels. In addition, this approach will decrease the overall production costs and aid in making an algal-based green economy viable. This mini review aims to provide certain information regarding development of and updates on cost-effective integrated biorefinery of algal-based bioproducts recovery and its potential application. In connection to this, life cycle assessment and techno-economic aspects of integrated algal biorefinery are discussed. Finally, present challenges and future research directions for integrated algal biorefinery are outlined.

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.
