Query: NC_015690:8019859 Paenibacillus mucilaginosus KNP414 chromosome, complete genome
Lineage: Paenibacillus mucilaginosus; Paenibacillus; Paenibacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Paenibacillus mucilaginosus is critical silicate bacteria in the biogeochemical cycling of potassium, phosphorus, and other soil elements, and is widely used in agriculture, bioleaching, and wastewater treatment. P. mucilaginosus is able to degrade insoluble soil minerals with the release of nutritional ions and fix nitrogen, and thus it has been successfully used as a biofertilizer since the 1990s. The exocellular polysaccharides produced by P. mucilaginosus is also an effective bioflocculant, and thus plays a potential role in the treatment of wastewater and biohydrometallurgy.
Subject: NC_011961:528837 Thermomicrobium roseum DSM 5159 plasmid unnamed, complete sequence
Lineage: Thermomicrobium roseum; Thermomicrobium; Thermomicrobiaceae; Thermomicrobiales; Chloroflexi; Bacteria
General Information: Thermomicrobium roseum DSM 5159 was isolated from Yellowstone National Park, USA. Obligate thermophile with unusual cell wall structure. Thermomicrobium roseum is a red-pigmented, rod-shaped, Gram-negative extreme thermophile that possesses both an atypical cell wall composition and an unusual cell membrane that is composed entirely of long-chain 1,2-diols. Analyses of environmental sequences from hot spring environments show that T.roseum displays a low quantity but ubiquitous presence in top layers of microbial mats. Few standard housekeeping genes are found on the megaplasmid, however, it does encode a complete system for chemotaxis including both chemosensory components and an entire flagellar apparatus. T. roseum oxidizes CO aerobically, making it the first thermophile known to do so. In addition, is is propose that glycosylation of its carotenoids plays a crucial role in the adaptation of the cell membrane to this bacterium's thermophilic lifestyle. Because T. roseum is a deep-branching member of this phylum, eventhough this species is not photosynthetic, analysis of the genome provides some insight into the origins of photosynthesis in the Chloroflexi.
