Macrocyclicus

Macrocyclicus is a genus of Gram-negative bacteria within the family Enterobacteriaceae. The genus was first discovered in 2011 and comprises 5 species: M. canadensis, M. desmacae, M. elongatus, M. hualiao, and M. corti.

Microbiologically, Macrocyclicus species are known to produce a yellow to brown pigment in their colonies. This pigment is a newly discovered compound, which has been found to have antioxidant properties. In addition, many Macrocyclicus species have been identified as being capable of nitrogen fixation, allowing them to thrive in environments where nitrogen is scarce.

Macrocyclicus species have been isolated from various environments, including freshwater sediment, estuarine water, and tissue of the marine mussel Mytilus galloprovincialis. These bacteria are primarily found in coastal areas, where they can contribute to the decomposition of organic matter and the recycling of nutrients.

Overall, research on Macrocyclicus is ongoing, and its discovery has contributed to the understanding of microbial ecosystems in diverse environments. Further study is needed to explore the full range of capabilities and potential applications of these bacteria.

Macrocyclicus species have been identified as capable of forming part of symbiotic relationships with eukaryotic organisms. This is an area of research that has significant implications for understanding microbial ecology and its relationship to the biology of partner organisms.
