The strain uses H2+CO2 or formate for growth and produces CH4. Optimum growth temperature is 40°C ; no growth is observed at 15°C or 45°C. Optimum pH for growth is 7 ; no growth is observed at pH 5.5 or 9.0. Strain FPiT is halotolerant and grows at NaCl concentrations of 0-25 g/l. The G+C content of its DNA is 31 mol%. Based on 16S rRNA gene sequence analysis, the isolate was identified as a new species of the genus #Methanobacterium$ : #Methanobacterium oryzae$ sp. nov. The type strain is FPiT (=DSM 11106T).
