A strain of Rhodopseudomonas palustris, which was isolated by enrichment with taurine, could use this as electron source, and as a source of sulfur and nitrogen during photo-autotrophic growth with CO2. Taurine was metabolized to sulfoacetaldehyde and acetyl phosphate by a pathway, which has already been noted (Novak et al. 2004).

Interestingly, autotrophic growth of S. brierleyi may also involve C02-fixation via a reductive cycle [52]. Wood et al. [13] could provide no further evidence for such a pathway, but suggest that the observed simultaneous use of acetate and CO2 for cellular biosyntheses indicates that the C02-fixing cycle must operate simultaneously with both assimilatory and oxidative pathways.

Cells grown under autotrophic growth condition (in BM) were disrupted by sonication for 1 min five times, and the hydrophobic fraction was extracted with pure redistilled chloroform. Acetone insoluble fraction of chloroform extracts was analyzed by TOF-MS (KOMPACT MALDl 11, Shimadzu, Kyoto, Japan) and its methanolysate was analyzed by GC/MS(E1) (JMS-DX303, JEOL, Tokyo, Japan). Acetone soluble fraction was directly analyzed by GC/MS(E1). HD-1 cell extract was prepared as follows autotrophically grown cells were centrifuged, washed, freeze-dried and weighed.

Chitnis, Reilly and Nelson obtained a mutant of Synechocystis sp. PCC 6803 that is devoid of PsaE and, although incapable of autotrophic growth, can grow normally in the presence of glucose. The PS-I RC complex prepared from this mutant could not photoreduce Ed but could mediate electron transfer from plastocyanin to artificial electron acceptors such as methyl viologen. Thus PsaE is demonstrated to promote and enhance the electron transfer between [EeS-A/B] and Ed.

Fig. 9.1 Cell-quota theory for control of photo-autotroph growth by internal nitrogen or phosphorus. Q is the cell quota for the nutrient, in atoms of the element per atom of organic carbon. kfj is the minimum value, or subsistence quota. /////1IU1X gives growth as a proportion of maximum rate. The function 10) multiplies nutrient uptake (which is also a function of ambient concentration) and brings it towards zero as Q tends towards (i llax. The third part of the diagram compares typical ranges of values of cellular N and P content and show how these contribute to variation in the cell N P ratio.
