Methanosarcina frisia accumulates phosphate up to 14% of its dry weight. The phosphate is stored as long-chain polyphosphates as shown by 31P-NMR investigations. Further results show that the accumulation of phosphates is substrate-dependent. In the presence of H2 and CO2 as the only carbon and energy source 180 mg of PO inf4 sup3- /g protein were accumulated, whereas 260 mg PO inf4 sup3- /g protein were accumulated in the presence of methanol. This is far more than necessary for the… CONTINUE READING
