16 The genus Methanocalculus comprises six validly published species including 17 Methanocalculus halotolerans, Methanocalculus pumilus, Methanocalculus taiwanensis, 18 Methanocalculus chunghsingensis, Methanocalculus natronophilus, and Methanocalculus 19 alkaliphilus. 20 Members of the genus Methanocalculus belong to the Methanocalculaceae family. They 21 have, with less than 90% 16S ribosomal RNA similarity, Methanoculleus and 22 Methanocorpusculum species as their closest phylogenetic relatives. Methanocalculus spp. 23 use only hydrogen and formate as substrates and require acetate as carbon source for 24 producing methane. They are mesophilic and have a G+C content in the DNA ranging from 25
