How can we explain the fact that a LAB stain that resists to low pH (2) becomes sensitive after 2 years of conservation at -20°C ? Notice that some problems of power cut occured during this time lapse.
Yes, it's possible for a probiotic lactic acid bacterium to lose its capacity to resist acid stress. Several factors can contribute to this loss of resistance, such as changes in the bacterium's environment, prolonged exposure to adverse conditions, genetic mutations, or alterations in the microbial community it interacts with. Additionally, improper storage or handling of probiotics can also lead to a decrease in their viability and ability to withstand stress factors like acidity. Regular monitoring and ensuring suitable conditions for storage and consumption can help maintain the viability and effectiveness of probiotics
