PHOTOBIOREACTOR

摘要

Provided herein is a transgenic bacteria engineered to accumulate carbohydrates, for example disaccharides. Also provided is a photobioreactor for cultivating photosynthetic microorganisms comprising a non-gelatinous, solid cultivation support suitable for providing nutrients and moisture to photosynthetic microorganisms and a physical barrier covering at least a portion of the surface of the cultivation support. Devices for the large scale and continuous cultivation of photosynthetic microorganisms incorporating photobioreactors and methods of use are disclosed. Also disclosed are methods of producing fermentable sugar from photosynthetic microorganisms using a photobioreactor of the invention.

主权项

1. A device for cultivating photosynthetic microorganisms, comprising;
a structure comprising a base, an axial support, and a plurality of suspension elements; the base maintaining the axial support in a substantially horizontal position; the plurality of suspension elements extending radially from and perpendicular to the axial support such that the axial support and plurality of suspension elements define a hub and spoke structure; wherein the axial support is configured to rotate with respect to the base and the plurality of suspension elements are configured to rotate around the axis defined by the axial support; a plurality of solid, non-gelatinous cultivation supports,
(i) each of the plurality of cultivation supports coupled to and positioned between at least two of the plurality of suspension elements, each of the plurality of cultivation supports extending substantially vertically with respect to the base and configured to maintain a substantially vertical position upon rotation of the plurality of suspension elements around the axis defined by the axial support; or(ii) each of the plurality of cultivation supports coupled to and positioned between at least two of the plurality of suspension elements, such that upon rotation of each of the plurality of suspension elements around the axis defined by the axial support, each of the cultivation supports is configured to transition between substantially horizontal and substantially vertical orientations; and a physical barrier disposed over at least a portion of the plurality of cultivation supports.
