Involvement of a Primary Electrogenic Pump in the Mechanism for HCO3− Uptake by the Cyanobacterium Anabaena variabilis1

AUTOR(ES)
RESUMO

The response of the membrane potential to HCO3− supply has been studied in the cyanobacterium Anabaena variabilis strain M-3 under various conditions. Changes in potential were followed with the aid of the lipophilic cation tetraphenyl phosphonium bromide.
