Abstract
Methods of storage and preservation of photosynthetically active cells and photosynthetic biomaterials are provided herein. Contemplated methods comprise storing the cells and biomaterials at a refrigeration temperature, optionally without light. The stored cells and biomaterials may be placed in a nitrogen containing medium under illumination before use. The chlorophyll content, oxygen consumption rate, oxygen production rate and/or morphology may be substantially preserved throughout the storage and awakening process.
Claims5
A preserved photosynthetic scaffold, comprising:
- photosynthetically active cells seeded onto a biomaterial;
- and
- wherein the photosynthetically active cells have been stored at temperatures between 1-5° C. without light for a period of at least 4 weeks.
