Bacteria (especially E. coli) may be used to replicate DNA in the form of a plasmid. This DNA is often chemically modified in vitro then inserted into bacteria to select for the desired traits and isolate the desired product from by-products of the reaction. After growing the bacteria and thereby replicating the DNA, the DNA may be further modified and inserted into other organisms. Bacteria may be used to produce large amounts of protein using genes encoded on a plasmid Bacterial genes have been inserted into other organisms as reporter genes. The yeast two-hybrid system combines bacterial genes with genes from the organism being studied and inserts them into yeast cells to study protein-protein interactions within a cellular environment. An ascomycete produces great numbers of asci at any one time, and these may be contained in a structure called an ascocarp. Each ascus contains eight (or a multiple of 8) ascospores, the result of one round of mitosis following meiosis. The resulting haploid nuclei are surrounded by membranes (from the plasma membrane in Euascomycetes; from the nuclear membrane in Hemiascomycetes) and eventually a spore wall.

Members of the species B. pertussis and occasionally B. parapertussis cause pertussis or whooping cough in humans. Several other species cause similar disease in other mammals, such as B. bronchiseptica, and in birds, such as B. avium and B. hinzii. Sphingomonas was defined in 1990 as a group of Gram-negative, rod-shaped, chemoheterotrophic, strictly aerobic bacteria that possess ubiquinone 10 as the major respiratory quinone, contain glycosphingolipids (GSLs) instead of lipopolysaccharide in their cell envelopes, and typically produce yellow-pigmented colonies. By 2001, the genus included more than 20 species that were quite diverse in terms of their phylogenetic, ecological, and physiological properties. As a result, the Sphingomonas were subdivided into four genera: Sphingomonas, Sphingobium, Novosphingobium and Sphingopyxis. The sulfate-reducing have been treated as phenotypic group, together with the other sulfur-reducing bacteria, for identification purposes. They are found in several different phylogenetic lines. Three lines are included among the Proteobacteria, all in the delta subgroup: Desulfobacterales Desulfovibrionales Syntrophobacterales A fourth group including thermophiles is given its own phylum, the Thermodesulfobacteria. The remaining sulfate-reducers are included with other bacteria among the Nitrospirae and the gram-positive Peptococcaceae - for instance Thermodesulfovibrio and Desulfotomaculum, respectively. There is also a single genus of Archaea capable of sulfate reduction, Archaeoglobus.
