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.
Claims20
A method of preserving photosynthetically active cells, comprising:
- storing photosynthetically active cells at temperatures between 1-5° C. without light for a period of at least 4 weeks;
- and
- suspending the photosynthetically active cells in a nitrogen-containing medium under illumination, wherein a chlorophyll content of the photosynthetically active cells after storing and suspending is at least 90% of the chlorophyll content of the photosynthetically active cells before storing and suspending.
A method for preserving photosynthetically active cells, comprising:
- storing the photosynthetically active cells at a temperature between 1-5 degrees Celsius without light.
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.
