Rhodococcus is a genus of obligate aerobic, nonmotile gram-positive bacteria, encapsulated intracellular bacillus. It is found in water and soil and causes pneumonia in young(1 to 6 months old) foals. Check out more information about my baby!
Gram-positive cells with a pronounced rod-coccus cycle. Cells in the early exponential phase are rod-shaped and cells in the stationary phase are coccoid. Catalase-positive. The genome sizes of the 22 Rhodococcus spp. varied from species to species (3.89-12.41 Mb).
Rhodococcus equi morphology varies from bacillary to coccoid, depending on growth conditions. In culture broth, bacteria are rod-shaped after 4 h of growth, while in liquid media or on blood agar, they are coccoid after a day(Bargen and Haas, 2009). The colonies of Rhodococcus equi are irregular, smooth, and mucoid, and they develop a salmon-pink color to yellow within a week(Bargen and Haas, 2009).
In the environment, Rhodococcus species are soil-borne organisms widespread in soil, rivers, and lakes(Valdzate 2022). Rhodococcus species can cause bone and joint infections in immunocompromised patients(Sowani et.al., 2017). Several studies have shown that Rhodococci directly incorporates unaltered and partially oxidized alkanes into their cell walls, in addition to nonpolar materials such as mycolic acids(Ward et.al., 2009).
Rhodococcus cells have aliphatic chains of mycolic acids in their cell wall, which allows them to adhere to oil/water interfaces, degrading hydrophobic pollutants(Bell et. al., 1998). In cold climates, Rhodococcus strains that are psychrotrophic may be useful for bioremediation(Bell et. al., 1998)
Rhodococcus strains contribute to fossil fuel biodesulfurization through their ability to catabolize a variety of compounds and produce bioactive steroids, acrylamide, and acrylic acid. Rhodococcus can also be applied to bioconversion, which is the process by which cheap starting materials are converted into more valuable compounds through biological processes, such as its ability to metabolize harmful environmental pollutants like toluene, naphthalene, herbicides, and PCBs.
Rhodococcus can also be applied to bioconversion, which is the process by which cheap starting materials are converted into more valuable compounds through biological processes, such as its ability to metabolize harmful environmental pollutants like toluene, naphthalene, herbicides, and PCBs. Typical Rhodococcus metabolism involves oxygenating an aromatic ring and forming the diol (two alcohol groups).
