Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
51 words
A method which comprises culturing Methylomonas sp. FERM P-2400 in an aqueous culture medium containing an assimilable nitrogen source and inorganic salts, in the presence of methane as the major carbon source, until the cells of said strain multiply in said culture medium, and recovering the multiplied cells from said medium.
Claim 2
Independent Claim
51 words
A method which comprises culturing Methylomonas sp. FERM P-2400 in an aqueous culture medium containing an assimilable nitrogen source and inorganic salts, in the presence of methane as the major carbon source, until the cells of said strain multiply in said culture medium, and recovering the multiplied cells from said medium.
Claim 3
Dependent Claim
