Microbial Fermentation Methods and Compositions

摘要

The present invention provides methods for the cultivation of the Methylobacterium genus of bacteria. In particular the method provides methods for the efficient and inexpensive cultivation of these bacteria. Additionally, the invention provides methods for the utilization of these bacterial cultures to improve plant agriculture.

主权项

1. A method for obtaining a Methylobacterium preparation comprising growing a mono-culture or co-culture of Methylobacterium in media that comprises a liquid phase and a solid phase, wherein said solid phase provides for increased yield of said Methylobacterium relative to yield obtained by growing the Methylobacterium in liquid media alone, and wherein said solid substance is not a viable photosynthetic microorganism, to provide a fermentation product with a Methylobacterium titer of 5×108 colony-forming units per gram of solid to about 5×1013 colony-forming units of Methylobacterium per gram of solid, thereby obtaining the Methylobacterium preparation.
