Distribution of Aerobic Bacteria Which Contain Bacteriochlorophyll a

Abstract

Sixteen strains of aerobic bacteria which contain bacteriochlorophyll a were isolated from the samples collected in aerobic marine environments: thalli of Enteromorpha linza, Porphyra sp., Sargussum horneri; beach sand; and the surface seawater from Aburatsubo Inlet. When they occurred, their proportions among the aerobic heterotrophic populations ranged from 0.9 to 1.1% in the seaweed samples and from 1.2 to 6.3% in the beach sand samples and were 0.9% in the seawater sample. The results suggested that the aerobic photopigmented bacteria widely inhabit aerobic marine environments.

Putative novel photosynthetic reaction centre organizations in marine aerobic anoxygenic photosynthetic bacteria: insights from metagenomics and environmental genomics

“…Indeed, in most species of anaerobic anoxygenic photosynthetic bacteria (AnAnP), the synthesis of photosynthetic apparatus is highly repressed by oxygen and modulated by light intensity (Bowman et al ., 1999). However, since 1979, when the first member of aerobic anoxygenic photosynthetic bacteria (AAnP) has been reported (Shiba et al ., 1979), many AAnP representatives were described from a wide variety of marine, freshwater and terrestrial habitats (Yurkov and Beatty, 1998). These bacteria grow photoheterotrophically, using light as an additional source of energy, and require oxygen for both growth and synthesis of their photosynthetic apparatus.…”

Influence of light and anoxia on chemiosmotic energy conservation in Dinoroseobacter shibae

“…Aerobic anoxygenic phototrophs (AAPs) are bacteria that carry out anoxygenic photosynthesis under oxic conditions. AAPs are not autotrophic and appear to use light energy as an additional, but never as their sole energy source (Shiba et al, 1979;Harashima et al, 1987). They form photopigments under suitable conditions only (Yurkov and Beatty, 1998;Kolber et al, 2001).…”

Distribution of aerobic anoxygenic phototrophs in temperate freshwater systems

“…In the late 1970s, an unusual kind of bacteria was discovered in Tokyo Bay, Japan (Harashima et al, 1978;Shiba et al, 1979). The isolates contained small amounts of bacteriochlorophyll a (BChl a), but in contrast to their close relatives, purple non-sulphur photosynthetic bacteria, they were obligate aerobes requiring oxygen for respiration and growth (Yurkov and Beatty, 1998).…”
