Photosynthesis was well-established on the earth at least 3.5 thousand million years ago,
and it is widely believed that these ancient organisms had similar metabolic capabilities to …

Photosynthetic organisms transform the energy of sunlight into chemical potential in a
specialized membrane-bound pigment-protein complex called the reaction center. Following …

In 1961, two concepts of energy coupling were published, one by Mitchell I and the other by
Williams z, both dealing with the transfer of charges (electrons, H÷, OH-) in biological energy …

Genome-resolved environmental metagenomic sequencing has uncovered substantial
previously unrecognized microbial diversity relevant for understanding the ecology and …

Green bacteria are a diverse group of chlorophototrophic organisms belonging to three
major taxa within the domain Bacteria: Chlorobi, Chloroflexi, and Acidobacteria. Most …

The primary processes of photosynthesis lead to transformation of solar radiation into
