描述了对绿屈菌（一种丝状光合细菌的新属）四种不同菌株的营养研究。这种生物体似乎与几种不同的原核生物群有关，特别是与绿硫细菌和蓝绿藻有关。然而，与这些自养生物不同的是，绿屈菌营养丰富，能够作为不依赖于光的异养生物在需氧条件下生长，并作为光合自养生物或光合异养生物在厌氧条件下生长。在各种生长条件下利用多种有机碳源，包括己糖、氨基酸、短链脂肪酸、有机酸和一些醇。这些结果表明，这种生物体可能是已知营养最丰富的生物体之一。
Nutritional studies on four different strains ofChloroflexus, a new genus of filamentous, photosynthetic bacteria are described. This organism appears to be related to several different procaryotic groups, and in particular to the green sulfur bacteria and blue-green algae. Unlike these autotrophs, however,Chloroflexusis nutritionally diverse, being able to grow aerobically as a light-independent heterotroph, and anaerobically as a photoautotroph or photoheterotroph. Numerous organic carbon sources including hexoses, amino acids, short chain fatty acids, organic acids, and some alcohols are utilized under various growth conditions. These results suggest that this organism may be among the most nutritionally versatile organisms known.
