title: [Prolonged afterglow of microorganisms].
abstract: The afterglow of some organisms is registered in the region of 460--540 nm at excitation in the 365 nm region. Apparently this effect is due to NAD and flavin containing coferments of proteins. The afterflow of NAD and riboflavin is also registered in thin films of albumin at excitation in 365 nm. The afterflow of NAD and riboflavin in thin protein films is similar to that spectrum of freezedried organisms' when the concentrations of these components are close to their concentrations in the cell.
