Aquatic phototrophs: efficient alternatives to land-based crops for biofuels

Dismukes, G Charles, Carrieri, Damian, Bennette, Nicholas, Ananyev, Gennady M, Posewitz, Matthew C·2008·Current Opinion in Biotechnology

Abstract

To mitigate some of the potentially deleterious environmental and agricultural consequences associated with current land-based-biofuel feedstocks, we propose the use of biofuels derived from aquatic microbial oxygenic photoautotrophs (AMOPs), more commonly known as cyanobacteria, algae, and diatoms. Herein we review their demonstrated productivity in mass culturing and aspects of their physiology that are particularly attractive for integration into renewable biofuel applications. Compared with terrestrial crops, AMOPs are inherently more efficient solar collectors, use less or no land, can be converted to liquid fuels using simpler technologies than cellulose, and offer secondary uses that fossil fuels do not provide. AMOPs pose a new set of technological challenges if they are to contribute as biofuel feedstocks.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Estimated costs of a barrel of algae-based fuel using current technology are US$300-2600, compared with $40-80 (2009) for petroleum.

    “estimated costs of a barrel of algae-based fuel using current technology is US$300–2600, compared with $40–80 (2009) for petroleum [9–12].”

  • There is no way to validate that the authors' model is correct, since a number of costs implicit in the model are estimates based on previous work and extrapolated from traditional agriculture data.

    “Similarly, there is no way to validate that our model is correct, since a number of costs implicit in the model are estimates based on previous work of others [9–12], and extrapolated from traditional agriculture data [39].”

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.
