Why is DMSO rather than Glycerol used while preparing cells for cryo, and why is glycerol used preferentially while storing microbial culture?

I would like to know which differences make these solutions suitable for these applications.

You can monitor singlet oxygen production by chemical method with DPBF (1,3-Diphenylisobenzofuran) in organic solutions and with ADMA (anthracene-9,10-diyl-bis-methylmalonate) in aqueous solution.
