| Description | Acinetobacter calcoaceticus is a Gram-negative, rod-shaped bacterium that thrives in a variety of environments. It is categorized as a psychrophilic, meaning it prefers temperatures between 10-30°C, making it well-suited for cold environments such as soil, water, and medical settings. This microbe is a chemoheterotroph, relying on organic compounds for its energy source, and produces energy through respiration. The Gram stain analysis reveals that A. calcoaceticus is characteristic of Gram-negative bacteria, possessing a thin peptidoglycan layer and an outer membrane. Its rod-shaped morphology allows it to multiply and adapt to different environments. This bacteria is commonly found on human skin, in the respiratory tract, and in the gastrointestinal tract, making it a ubiquitous microbe. A. calcoaceticus is an obligate aerobe, requiring the presence of oxygen for growth and metabolism. It is sensitive to low oxygen levels and cannot survive in anoxic environments. In contrast, some bacteria can thrive in low-oxygen conditions or even anaerobic environments. Despite its ability to adapt to various environments, A. calcoaceticus is primarily found in soil, water, and clinical settings. It is often associated with hospital-acquired infections, particularly in patients with compromised immune systems. Notably, A. calcoaceticus has been recognized as a multidrug-resistant pathogen, contributing to the challenge of treating associated infections. One critical role A. calcoaceticus plays is as a biosensor for environmental pollutants. Its ability to degrade certain pollutants, such as polycyclic aromatic hydrocarbons (PAHs), makes it a valuable tool for monitoring environmental contamination. Furthermore, its genetic makeup has shown promise in the development of novel enzymes and bioproducts, highlighting the significant potential of this microbe in biotechnological applications. In summary, A. calcoaceticus is a versatile, opportunistic microbe with a complex range of characteristics. Its ability to thrive in diverse environments, degrade pollutants, and produce novel bioproducts make it a fascinating subject for ongoing research and exploration. |
