N2 - For over a century, taxonomically validated pure cultures of aerobic methanotrophs belonged to Pseudomonadota, or since 2007, Verrucomicrobiota. A recent article published in Applied and Environmental Microbiology by H. Kambara, T. Kawamoto, S. Matsushita, T. Kindaichi, et al. (91:e00796-25, 2025, https://doi.org/10.1128/aem.00796-25) expands the phylogenetic radiation of aerobic methanotrophs to the Actinomycetota with the description of Ca. Mycobacterium methanica MM1. This isolate confirms and strengthens the position of the genus Mycobacterium as methanotrophs displaying a wide pH and ammonia tolerance and expanding the habitat range for methane capture.
