Surcrose uptake by Neisseria denitrificans.
Neisseria dentrificans possesses an inducible sucrose-uptake system. Sucrose is transported as the free sugar and is rapidly converted into polymerized material. Uptake is inhibited by glucose, cyanide, uncouplers of oxidative phosphorylation, and sulfydryl reagents. Glutamate serves as an energy source for uptake. The importance of this phenomenon in the oral environment is discussed.
