Abstract

Summary: Inoculation of samples from a small eutrophic pond into pyruvate/malate medium at neutral pH yielded a new species of the described here as The cells are ovoid to rod-shaped, 1 to 2.5 μm long and 0.6 to 0.8 μm wide, non-motile and multiply by a process of sessile budding. The photosynthetic membrane system consists of lamellae parallel to and underlying the cell membrane. The photopigments consist of bacteriochlorophyll and carotenoids of the spheroidene group. Cells can grow anaerobically in the light using a wide range of organic compounds. Aerobic growth in the dark is also possible. Nicotinic acid and thiamin are required as growth factors. Good photolithotrophic growth with H is possible, but sulphide and thiosulphate cannot be used as electron donors. As this species has properties lying between the two groups of existing species, i.e. those which show intercalary growth and those which multiply by budding (asymmetric polar growth), a new species is hereby proposed.
