- ... Metamitron (1) does not undergo hydrolysis at pH 1-8 and up to 5 M H2SO4. The product of its two-electron reduction, 1,6-dihydrometamitron (2), on the other hand, undergoes at pH <3 relatively fast hydrolysis. The dependence of the measured rate constant on acidity indicates that the completely protonated form (AH2 2+) predominating in strongly acidic media undergoes hydrolysis slower than the spe ...

- ... The ultrastructure of vegetative cells and spores of Bacillus pulvifaciens was studied by CTEM and SEM methods. The vegetative cells are rods, 1.6-4.5 micrometers long and 0.4-0.6 micrometers wide, exhibiting typical ultrastructural features of Gram-positive bacteria. The spores are of ellipsoidal shape, 0.6 X 1.2 micrometers in size, with six longitudinal ribs reaching up to 130 nm in height. The ...
