开发了含有18%（wt/wt）甘油和2 μ g二氯烷/ml的低水活度（aw）培养基（0.95 aw），用于计数干燥和半干燥食品的真菌植物群。命名为DG 18的培养基在用食品和纯培养物接种物测试时明显优于Christensen麦芽盐糖。通过比较两种高aw培养基上获得的真菌计数，证明了需要一种减少aw的培养基来计数低水分食品中的嗜干真菌。
A low water activity (aw) medium (0.95 aw) containing 18% (wt/wt) glycerol and 2 .mu.g of dichloran/ml was developed for enumerating the fungal flora of dried and semidried foods. The medium, designated DG18, was significantly better than Christensen malt salt sugar when both media were tested with foodstuffs and with pure culture inocular. The need for a medium of reduced aw for enumerating xerophilic fungi from low-moisture foods was demonstrated by comparing fungal counts obtained on both high-aw media.
