Anaerobic respiration in the Rhodospirillaceae: characterisation of pathways and evaluation of roles in redox balancing during photosynthesis

Abstract

Recent discoveries relating to pathways of anaerobic electron transport in the Rhodospirillaceae are reviewed. The main emphasis is on the organism Rhodobacter capsulatus ** but comparisons are made with Rhodobacter sphaeroides * * f. sp. denitrificans and Rhodopseudomonas palustris. The known electron acceptors for anaerobic respiration in Rhodobacter capsulatus are trimethylamine-N-oxide (TMAO), dimethyl sulphoxide
