New evolutionary study shows evidence for LUPA (Last Universal Photosynthetic Ancestor) Life on Earth as we know it essentially depends on photosynthesis. The process of photosynthesis is arguably the most important biochemical process on the planet because it captures the energy from the sun and produces biomass to support nearly all life on Earth. You may associate photosynthesis mainly with plants or algae, which are important contributors to this process, however there… Read More
Bellevue University professor John Kyndt, will be one of nine speakers to take the stage and present his ideas that push the boundaries of the unknown at the TEDx Omaha event, “EDGE,” set for Saturday, Nov. 18 at Creighton University. Dr. Kyndt, who is a Professor of Microbiology and Sustainability at Bellevue University, will talk about his focused research on the genomics and biochemistry of bacteria and viruses from extreme environments, to… Read More
The evolution of phototrophic bacteria and photosynthesis in general is certainly an interesting but complex topic. It is commonly well accepted that anoxygenic phototrophy evolved well before the gradual oxygenation of the Earth. This means that the photosynthetic machinery of anaerobic phototrophic bacteria (like purple and green bacteria) evolved well before the existence of oxygenic photosynthesis of algae and plants. One of the best studied model organisms for studying photosynthesis in purple… Read More
It is not every day that an entire bacterial genus is discovered and reclassified. We are lucky when occasionally we find a new species, but that alone certainly does not redefine an entire genus. It took the sequencing and comparative analysis of eight new genomes, in addition to the three known genomes of heliobacteria, to come to this discovery. The family of heliobacteria are a small group of phototropic bacteria that were… Read More
