Phys · · 675 words · By Sven-David Müller
Scientific Methodology Biodiversity and Conservation Microbiological Discovery

Researchers at the Leibniz Institute DSMZ have identified a new phototrophic myxobacterium, Candidatus Photomyxococcus marinus, within the microbiome of the cyanobacterium Coleofasciculus. The study utilized high-throughput sequencing and metagenomics to characterize the diverse bacterial community associated with these marine organisms.
