Abstract
This disclosure provides compositions and methods for culturing microorganisms. The disclosure includes mixtures of different microorganisms, especially mixtures of cyanobacteria with fermentative microorganisms. For example, methods and compositions related to co-cultures of yeast and cyanobacteria are provided. Also provided are feedstocks derived from cyanobacteria as well as methods of making such feedstocks and methods of culturing microorganisms in such feedstocks.
Claims8
A method comprising:
- a. culturing a consortium of cyanobacteria comprising Synechococcus CCMP 1333, Synechococcus PCC 7002, and Cyanothece in a culture medium that comprises a salt concentration greater than or equal to 0.08% (w/v) to produce sugars and polysaccharides;
- and
- b. removing cyanobacteria from the culture in order to obtain a feedstock medium containing sugars and polysaccharides that is substantially free of cyanobacteria.
