Oven drying will have killed most of the vegetative non-spore forming microbes. GYEA medium is particularly selective for the ''Streptomyces'' group of endospore formers because of the osmotic pressure obtained from the high concentration of glycerol. Few bacteria can thrive in GYEA which favors the growth of members of the Streptomyces group of Gram positive bacteria. <BR> | Oven drying will have killed most of the vegetative non-spore forming microbes.
