1. A solid containing a reversibly preserved microorganism in a dormant and preserved state comprising:
a cured suspension comprising the microorganism in an isolated condition combined with an effective amount of a pullulan solution, wherein said suspension is cured under ambient conditions to form a solid containing said microorganism in a dormant and preserved state;
wherein the suspension can be restored by irrigating said solid under ambient conditions with an effective amount of an aqueous solution to restore said suspension and the suspension can be separated such that said microorganism is restored to said isolated condition.
