Wild-type strains of the cellular slime mold Dictyostelium discoideum grow on bacteria. Axenic strains of D. discoideum capable of growing in a simple salts-yeast extract-proteose peptone-glucose medium have been isolated from wild-type strains fo both mating types after a single passage in this medium. This result is consistent with the theory that the axenic phenotype has a simple genetic basis.
细胞黏菌盘基网柄菌的野生型菌株以细菌为食生长。在简单的盐-酵母提取物-蛋白胨-葡萄糖培养基中能够生长的盘基网柄菌无菌株,是从两种交配型的野生型菌株在该培养基中传代一次后分离得到的。这一结果与无菌表型具有简单遗传基础的理论相一致。
