Abstract
The present invention generally relates to compositions and methods of delivering living cells in a dry mode, wherein the compositions include a surface layer disposed on the outer surface of the composition that is permeable to carbon dioxide and oxygen. The compositions may be used to deliver living cells to a delivery point without the use of expensive refrigerants such as dry ice or liquid nitrogen.
