Together, members of these genera make up only 2.7 to 3.7% of soil bacteria. Clostridium botulinum C. botulinum is a gram-positive bacterium (i.e. Delgado-Baquerizo et al. Genus Proteus contains rod-shaped bacteria that inhabit soil and water. The genus received its current name, after the British pioneer of sterile surgery Joseph Lister, in 1940. The Actinobacteria are a phylum of Gram-positive bacteria.They can be terrestrial or aquatic. Soil bacteria play key roles in regulating terrestrial carbon dynamics, nutrient cycles, and plant productivity. Mycobacterium vaccae is a nonpathogenic species of the Mycobacteriaceae family of bacteria that lives naturally in soil.Its generic name originates from the Latin word, vacca (), since the first Mycobacterium strain was cultured from cow dung in Austria. Until 1992, 10 species were known, each containing two subspecies. The 14 genera of soil bacteria with the most deposited cultures, together encompassing over half of all soil-derived isolates in the ATCC, are also not common among the clones detected in libraries (Table 2). They are of great economic importance to humans because agriculture and forests depend on their contributions to soil systems. Geobacter is a genus of Proteobacteria. A few species of bacteria in the soil can prove dangerous or even deadly to humans as well. Listeria is a genus of bacteria that acts as an intracellular parasite in mammals. However, the natural histories and distributions of these organisms remain largely undocumented. Species in the genus produce urease. Clostridium, genus of rod-shaped, usually gram-positive bacteria, members of which are found in soil, water, and the intestinal tracts of humans and other animals.Most species grow only in the complete absence of oxygen. Dormant cells are highly resistant to … provide a survey of the dominant bacterial taxa found around the world. a bacterium that tests positive on the Gram staining test) that forms hardy, durable spores. By 2020, 21 species had been identified. Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Firmicutes, with 266 named species.The term is also used to describe the shape (rod) of certain bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs. Geobacter species are anaerobic respiration bacterial species which have capabilities that make them useful in bioremediation. The bacterial genus Morganella should not be confused with the fungal genus of the same name.
