<p>A composition for preserving viable microorganisms, cells or tissue comprises (a) a preservative combination of (i) a non-reducing disaccharide and (ii) a bulking agent; and (b) a buffer. Also described is a method of preserving viable microorganisms, cells or tissue, comprising combining viable microorganisms, cells or tissue with a preserving solution comprising a non-reducing disaccharide, drying the combination to form a dried preparation having a solids content of at least 80 % by weight, and counting the viable microorganisms, cells or tissue in the dried preparation, whereby the dried preparation can be combined with aqueous buffer to yield an aqueous preparation comprising a predetermined count of viable microorganisms, cells or tissue.</p> |
