I use saline (0.9%NaCl) to resuspend bacterial cells for inoculation. My question is for how much time can I use this suspension in my experiments?
From my experiments, they can withstand for 3 days for sure. I did not try longer time. Worth to try it though.
What is the difference between broad and sharp cyclic volatmmetric curves? and what are the reasons for broad curve? especially when analyzing carbon material?
