Salmonella newport and Pseudomonas fluorescens were dried together in papain digest broth and sucrose-glutamate, and stored in several gases at various water activities (a(w)) between 0.00 and 0.40 at 25 C for various periods up to 81 weeks. Both S. newport and P. fluorescens, dried in papain digest broth and stored in air, died rapidly if the conditions were very dry (0.00 a(w)) or moist (0.40 a(w)). Storage in carbon dioxide and argon gave greater survival than storage in air but lower survival than did storage in nitrogen or in vacuo. When the organisms were dried in a sucrose-glutamate mixture the differences between the gases were very small, and variations in residual water were less important. Of the inert gases, argon gave the best survival when the organisms were dried in papain digest broth, especially at 0.00 a(w); the survival in neon and krypton was lower and in xenon and helium it was much lower.
新港沙门氏菌和荧光假单胞菌在木瓜蛋白酶消化肉汤和蔗糖 - 谷氨酸中共同干燥，并在25℃下于0.00至0.40之间的各种水分活度（a(w)）下，在几种气体中储存长达81周的不同时间段。新港沙门氏菌和荧光假单胞菌在木瓜蛋白酶消化肉汤中干燥并储存在空气中，如果条件非常干燥（a(w) 0.00）或潮湿（a(w) 0.40），则会迅速死亡。储存在二氧化碳和氩气中的存活率高于储存在空气中，但低于储存在氮气或真空中的存活率。当生物体在蔗糖 - 谷氨酸混合物中干燥时，气体之间的差异非常小，残留水分的变化不太重要。在惰性气体中，当生物体在木瓜蛋白酶消化肉汤中干燥时，氩气的存活率最高，特别是在a(w) 0.00时；在氖气和氪气中的存活率较低，在氙气和氦气中的存活率则低得多。
