The microorganisms of this genus require sodium chloride concentrations in the moderately halophilic range of 1.0 to 2.5 M for optimal growth and methanogenesis. Methanol and methylamines are the substrates that are utilized for growth. M. mahii is a methanogenic coccoid microorganism isolated from the sediments of the Great Salt Lake. The optimum temperature and salinity for growth and methanogenesis were 37°C and 2.0 M NaCI, respectively. The description is based on a single strain, strain SLP (= ATCC 35705), which is thus the type strain., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-38-1-122
