“…The genes which control the biosynthesis of the bacterial photosynthetic apparatus were believed to be located in the chromosome and not in any of the extrachromosomal elements [13]. This idea was supported by the observation that the wild-type strain 37b4 of R. capsulata does not contain extrachromosomal elements [14].…”

“…In Rb. sphaeroides, several studies have shown a correlation between the loss or rearrangement of plasmid DNA and the loss of photosynthetic capacity following treatment with plasmid-curing agents [44,45]. However, no gene essential for photosynthesis has been definitively assigned to these plasmids.…”

The biochemical genetics approach is defined as the use of mutants, in comparative studies with the wild‐type, to obtain information about biochemical and physiological processes in complex metabolic systems. This approach has been used extensively, for example in studies on the bioenergetics of the photosynthetic bacteria, but has been applied less frequently to studies of intermediary carbon and nitrogen metabolism in phototrophic organisms. Several important processes in photosynthetic bacteria—the regulation of nitrogenase synthesis and activity, the control of intracellular redox balance during photoheterotrophic growth, and chemotaxis—have been shown to involve metabolism. However, current understanding of carbon and nitrogen metabolism in these organisms is insufficient to allow a complete understanding of these phenomena. The purpose of the present review is to give an overview of carbon and nitrogen metabolism in the photosynthetic bacteria, with particular emphasis on work carried out with mutants, and to indicate areas in which the biochemical genetics approach could be applied successfully. In particular, it will be argued that, in the case of Rhodobacter capsulatus and Rb. sphaeroides, two species which are fast‐growing, possess a versatile metabolism, and have been extensively studied genetically, it should be possible to obtain a complete, integrated description of carbon and nitrogen metabolism, and to undertake a qualitative and quantitative analysis of the flow of carbon and reducing equivalents during photoheterotrophic growth. This would require a systematic biochemical genetic study employing techniques such as HPLC, NMR, and mass spectrometry, which are briefly discussed. The review is concerned mainly with Rb. capsulatus and Rb. sphaeroides, since most studies with mutants have been carried out with these organisms. However, where possible, a comparison is made with other species of purple non‐sulphur bacteria and with purple and green sulphur bacteria, and recent literature relevant to these organisms has been cited.

“…The photosynthetic bacterium Rhodopseudomonas sphaeroides is increasing in importance as a model system in studies of microbial physiology [1,2]. This is not only due to its photosynthetic ability but also because it is capable of photochemical nitrogen fixation and the photoevolution of hydrogen [3].…”
