👉 "Dechlorobacter" is a genus of bacteria that belongs to the phylum Firmicutes, which are part of the Kingdom Proteobacteria and Class Bacteria. They primarily live in aquatic environments such as lakes, rivers, and oceans. Dechlorobacteria play a crucial role in the decomposition of organic matter in these water bodies by breaking down chlorophyll, which is essential for photosynthesis, into simpler compounds like carbon dioxide and water.
