Relationship between ion requirements for respiration and membrane transport in a marine bacterium alteromonas haloplanktis


, : Relationship between ion requirements for respiration and membrane transport in a marine bacterium alteromonas haloplanktis. Journal of Bacteriology 157(1): 59-63

Intact cells of the marine bacterium A. haloplanktis 214 oxidized NADH, added to the suspending medium, by a process which was stimulated by Na+ or Li+ but not K+. Toluene-treated cells oxidized NADH at 3 times the rate of untreated cells by a mechanism activated by Na+ but not by Li+ or K+. In the latter reaction, K+ spared the requirement for Na+. Intact cells of A. haloplanktis oxidized ethanol by a mechanism stimulated by Na+ or Li+. The uptake of .alpha.-aminoisobutyric acid by intact cells of A. haloplanktis in the presence of either NADH or ethanol as an oxidizable substrate required Na+, and neither Li+ nor K+ could replace it. Thus, exogenous and endogenous NADH and ethanol are oxidized by A. haloplanktis by processes distinguishable from each other by their requirements for alkali metal ions and from the ion requirement for membrane transport. Intact cells of Vibrio natriegens and Photobacterium phosphoreum oxidized NADH, added externally, by an Na+-activated process; intact cells of V. fisheri oxidized NADH, added externally, by a K+-activated process. Toluene treatment caused the cells of all 3 organisms to oxidize NADH at much faster rates than untreated cells by mechanisms which were activated by Na+ and spared by K+.
