Abstract
The cryoprotectant presents remarkable effect on increasing the survival rate and stability of freeze-dried Pseudomonas sp. powder. Here single-factor and orthogonal experimental designs were conducted to screen the optimal combination of cryoprotectant. The results showed that the survival rate reached 90% when the concentration of skim milk powder,sorbitol,glycerol,and L-sodium ascorbate were 10%,3%, 1%,2%,and was 50.2% while stored for 6 months at 25℃ .关键词
