Effect of oleic acid on the viability of different freeze-dried Lactiplantibacillus plantarum strains

Freeze drying is one of the most convenient ways to preserve microorganisms, but in the freeze-drying process, strains will inevitably suffer varying degrees of damage under different conditions. The deterioration of cell membrane integrity is one of the main forms of damage. The type and ratio of fatty acids in the cell membrane affect its characteristics. Therefore, it is worth investigating whether certain fatty acids can increase...
