Color atlas and textbook of diagnostic microbiology, 1997). Streptococcus oralis is implicated in meningitis in patients with decreased immune function...
The mechanisms of the electrode reduction of vitamin B12a and the reductive cleavage of glutathionyl cobalamin (GSCbl) were investigated with digital simulations in acid media at pH 3.78 and 2.78. Even though the pH is quite acidic, the 1‐electron reduction of B12a goes through the base‐on form in a step‐wise sequence forming base‐on vitamin B12r which then is protonated to the base‐off form, and...
