| Abstract: | The anaerobic metabolism of marginally lethal levels of 13C]formaldehyde by Escherichia coli (K12, MU352, CRB, and CR63) was followed in vivo by 13C NMR. The products include 1,2-propanediol. Under aeration, the 1,2-propanediol is converted to hydroxyacetone. The hydroxyacetone is reconverted to 1,2-propanediol when aeration is stopped. The process can be cycled by varying the rate of aeration. |
