    Notes: Abstract Methanobacterium thermoautotrophicum was grown in a fermenter gassed with an 80% H2/20% CO2 mixture. The effluent gas was found to contain between 30 ppm and 90 ppm carbon monoxide. Approx. 5 nmol CO were produced per min and mg cells (dry weight) by the culture. This is to our knowledge the first report on biological carbon monoxide formation under strictly anaerobic conditions.

    Acetate thiokinase and the assimilation of acetate in Methanobacterium thermoautotrophicum (1980)
    Springer
    Archives of microbiology 128 (1980), S. 248-252

    Notes: Abstract Methanobacterium thermoautotrophicum growing on H2 plus CO2 as sole carbon and energy source was found to contain acetate thiokinase (Acetyl CoA synthetase; EC 6.2.1.1): Acetate+ATP+CoA → Acetyl CoA+AMP+PPi. The apparent K m value for acetate was 40 μM. Acetate kinase (EC 2.7.2.1) and phosphotransacetylase (EC 2.3.1.8) could not be detected. The specific activity of acetate thiokinase was high in cells grown with limited H2 and CO2 supply (approximately 100nmol/min · mg protein), it was low in exponentially grown cells (2 nmol/min·mg protein). This corresponded with the finding that cells growing linearly in the presence of acetate assimilated the monocarboxylic acid in high amounts (〉10% of the cell carbon was derived from acetate), whereas exponentially growing cells did not (〈1% of cell carbon was derived from acetate). These latter observations indicated that acetate thiokinase and free acetate are not involved in autotrophic CO2 fixation in M. thermoautotrophicum. The presence and some kinetic properties of succinate thiokinase (EC 6.2.1.5), adenylate kinase (EC 2.7.4.3), and inorganic pyrophosphatase (EC 3.6.1.1.) are also described.

    Incorporation of 8 succinate per mol nickel into factors F430 by Methanobacterium thermoautotrophicum (1980)
    Springer
    Archives of microbiology 128 (1980), S. 256-262

    ISSN: 1432-072X
    Keywords: Factors F430 ; Methanobacterium thermoautotrophicum ; Nickel ; Tetrapyrrole biosynthesis ; Succinate incorporation ; Methanobacterium bryantii
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Factors F430 from methanogenic bacteria have recently been shown to contain nickel and it has been speculated that they may have a nickel tetrapyrrole structure. This assumption was tested by determining whether succinate is incorporated by growing Methanobacterium thermoautotrophicum into three factors F430. Succinate is assimilated by Methanobacterium thermoautotrophicum into the amino acids glutamate, arginine and proline and into tetrapyrroles rather than other cell components. It was found that per mol nickel 8–9 mol of succinate were incorporated into the three factors F430 which is the amount predicted for a tetrapyrrole structure. Since the three factors F430 only contained significant amounts of glutamate rather than arginine or proline, the incorporation data suggest that factors F430 are nickel tetrapyrrole compounds. Spectral properties of the three factors F430, apparent molecular weights, and the absence of phosphor in these compounds are also described.

    Electrogenic sodium ion/proton antiport in Desulfovibrio vulgaris (1983)
    Springer
    Archives of microbiology 136 (1983), S. 69-73

    ISSN: 1432-072X
    Keywords: Desulfovibrio vulgaris ; Sodium transport ; Na+/H+ antiport ; Dissimilatory sulfate reduction ; Sulfate transport

    Topics: Biology
    Notes: Abstract Entry of sodium ions into cells of Desulfovibrio vulgaris was studied. Translocation of Na+ was monitored by following the optical changes associated with shrinkage and swelling of the cells upon exposure to a hyperosmotic solution (200 mM) of sodium acetate or of sodium thiocyanate. By this technique the two solutes were found to equilibrate only after the addition of a protonophore such as carbonylcyanide m-chlorophenyl-hydrazone (CCCP). It was confirmed that acetate permeates electroneutrally as CH3COOH and thiocyanate electrogenically as SCN-. These findings suggest that Na+ is translocated by an electrogenic sodium ion/hydrogen ion antiport mechanism (H+/Na+〉1). Consistent with this interpretation is the observation that the addition of sodium acetate to a cell suspension resulted in the generation of a membrane potential (inside negative) and that of NaCl in an acidification of the external medium.

    Propionate assimilation by methanogenic bacteria (1983)

    Topics: Biology
    Notes: Abstract Methanobacterium thermoautotrophicum, Methanobrevibacter arboriphilus, and Methanosarcina barkeri were found to assimilate propionate when growing on media supplemented with this volatile fatty acid. [1-14C]propionate was almost exclusively incorporated into isoleucine, only C-2 of which became labelled. Assimilation of propionate by M. thermoautotrophicum was specifically inhibited by isoleucine, by 2-methylbutyrate, and by 2-oxobutyrate, whereas there was little or no effect by leucine, valine, butyrate, and acetate. This finding indicates that propionate assimilation is under regulatory control by intermediates and/or the product of isoleucine biosynthesis.

    Studies on the biosynthesis of coenzyme F420 in methanogenic bacteria (1984)

    Keywords: Coenzyme F420 ; Flavin biosynthesis ; Deazaflavins ; Guanine assimilation ; Methanogenic bacteria ; Methanobacterium thermoautotrophicum

    Topics: Biology
    Notes: Abstract Coenzyme F420 is a 8-hydroxy-5-deazaflavin present in methanogenic bacteria. We have investigated whether the pyrimidine ring of the deazaflavin originates from guanine as in flavin biosynthesis, in which the pyrimidine ring of guanine is conserved. For this purpose the incorporation of [2-14C]guanine and of [8-14C]guanine into F420 by growing cultures of Methanobacterium thermoautotrophicum was studied. Only in the case of [2-14C]guanine did F420 become labeled. The specific radioactivity of the deazaflavin and of guanine isolated from nucleic acids of [2-14C]guanine grown cells were identical. This finding suggests that the pyrimidine ring of the deazaflavin and of flavins are synthesized by the same pathway. F420 did not become labeled when M. thermoautotrophicum was grown in the presence of methyl-[14C] methionine, [U-14C]phenylalanine or [U-14C]tyrosine. This excludes that C-5 of the deazaflavin is derived from the methyl group of methionine and that the benzene ring comes from phenylalanine or tyrosine.
