Green sulfur bacteria examples
WebA chlorosome is a photosynthetic antenna complex found in green sulfur bacteria (GSB) and many green non-sulfur bacteria (GNsB), together known as green bacteria. They differ from other antenna complexes by their large size and lack of protein matrix supporting the photosynthetic pigments. Green sulfur bacteria are a group of organisms that … WebThe two different types of autotrophic bacteria are: Photoautotrophs – or photosynthetic. They derive energy from sunlight. Chemoautotrophs – or chemosynthetic. They use chemical energy to prepare their food. Apart from energy requirements, both types of bacteria need a carbon source to synthesize their food, e.g. carbon dioxide and other ...
