| Abstract: | The manganese electron paramagnetic spin resonance spectrum of Bacillis megaterium KM spores is virtually identical at both 77 K and 298 K which suggests that the manganese is present in a crystalline lattice in the spore core. This conclusion is supported by studies of the electron paramagnetic resonance spectra of model systems including Ca: Mn: pyridine-2,6-dicarboxylic acid crystals and manganese bound to protein and lipid standards. |
