Acinetobacter calcoaceticus

Acinetobacter calcoaceticus is a Gram-negative, rod-shaped bacterium that typically exists as single cells and is characterized by its lack of motility, despite possessing flagella. This organism is classified as an aerobe and a chemoheterotroph, meaning it requires oxygen for growth and derives its energy from organic compounds. It thrives optimally at a temperature of 37°C, placing it within the mesophilic temperature classification. The cellular structure of A. calcoaceticus includes two membranes, consistent with its Gram-negative classification, and it possesses a genomic architecture characterized by two replicons, as indicated by its genome accessions NZ_LT605060.1 and NZ_LS999521.1. The bacterium is free-living and can be found in a variety of habitats, suggesting a versatile ecological role. A notable aspect of A. calcoaceticus is its adaptability to diverse environments, which may contribute to its persistence in various ecological niches, potentially influencing its interactions with other microorganisms and its role in nutrient cycling. This adaptability underscores the ecological significance of A. calcoaceticus within microbial communities.
