“…Also, some 20 strains of pink, facultative methanol users obtained from Hayward (18) failed to use methane (J. J. Perry, unpublished data; see also 22). Similar results have been reported for 15 strains of facultative methanol-utilizing bacteria reclassified as Vibrio extorquens (49) and for several strains of the budding bacterium Hyphomicrobium (19). Thus, bacteria isolated by selective culture techniques as methanol utilizers invariably have been incapable of growth at the expense of methane.…”

FosTER, J. W. (The University of Texas, Austin), AND RICHARD H. DAVIS. A methane-dependent coccus, with notes on classification and nomenclature of obligate, methane-utilizing bacteria. J. Bacteriol. 91:1924-1931. 1966.-A new coccusshaped bacterium capable of aerobic growth at the expense of methane or methanol in a mineral salts medium is described. The organism did not grow at the expense of any of the conventional substrates or homologous hydrocarbons tested. It is gram-negative, nonmotile, and thermotolerant. It grows well at 50 C, optimally at 37 C, but does not grow at 55 C. The cells are encapsulated and have a characteristic diplococcoid arrangement. Washed, "resting-cell" suspensions oxidized certain primary alcohols and short-chain alkanes, an example of "nongrowth oxidation." Of the methane-C utilized, 86% was "fixed" in organic form; the remainder was oxidized to CO2. The guanine-cytosine content of the extracted deoxyribonucleic acid was 62.5%. Obligate methane-utilizing bacteria are considered as "one-carbon" organisms rather than hydrocarbon utilizers. The assimilation pathway in the obligate methane-methanol bacteria is different from that in the facultative methanol utilizers. Nomenclatural problems arising from the use of the prefix "Methano-" to denote both bacteria that oxidize methane and bacteria that produce methane are discussed. The obligate, one-carbon, methane-methanol bacteria are considered as "methyl" utilizers, and the prefix "Methylo-" is suggested as a solution to the problem of generic cognomens. "Methylococcus capsulatus" gen. n., sp. n. is the name proposed for the new methane coccus.

“…Strains of cluster 1 resembled the pink bacteria described previously, including B. (Vibrio) extorquens (11,13), Protaminobacter ruber (11,13), M. rubra (4), Pseudomonas methanica 7, unnamed Pseudomonas species with alphanumeric designations (1, 8, 11), and the type strain Pseudomonas mesophilica (2, 14). These slow-growing red chromogens are described as straight, slightly curved, vacuolated rods that are motile by means of a single polar flagellum and which produce catalase and oxidize methanol.…”

Twenty-one strains of pink-pigmented bacteria, isolated from human clinical specimens and an environmental source, were compared with Pseudomonas mesophilica ATCC 29983 and Protaminobacter ruber ATCC 8457. These isolates were gram-negative, oxidative rods which were motile by means of a single polar flagellum; gave positive catalase, indophenol oxidase, urease, and amylase reactions; and grew slowly at 30°C. Fourteen isolates conformed to the designated type strains Pseudomonas mesophilica ATCC 29983 and Protaminobacter ruber ATCC 8457. The remaining seven strains represented an undescribed taxon. These pink bacteria appear to be invaders of debilitated patients with an underlying chronic disease.

“…ruber and P8. extorquen8 are all pink-pigmented bacteria that are capable of growth on several C, compounds and also on a wide variety of other substrates, including oxalate (Stocks & McCleskey, 1964). Stocks & McCleskey (1964) consider that they are sufficiently alike to be considered one species and suggest that they be tentatively considered as strains of Vibrio extorquens (Bassalik).…”

Microbial growth on oxalate by a route not involving glyoxylate carboligase

1. The metabolism of oxalate by the pink-pigmented organisms, Pseudomonas AM1, Pseudomonas AM2, Protaminobacter ruber and Pseudomonas extorquens has been compared with that of the non-pigmented Pseudomonas oxalaticus. 2. During growth on oxalate, all the organisms contain oxalyl-CoA decarboxylase, formate dehydrogenase and oxalyl-CoA reductase. This is consistent with oxidation of oxalate to carbon dioxide taking place via oxalyl-CoA, formyl-CoA and formate as intermediates, and also reduction of oxalate to glyoxylate taking place via oxalyl-CoA. 3. The pink-pigmented organisms, when grown on oxalate, contain l-serine-glyoxylate aminotransferase and hydroxypyruvate reductase but do not contain glyoxylate carboligase. The converse of this obtains in oxalate-grown Ps. oxalaticus. This indicates that, in contrast with Ps. oxalaticus, synthesis of C(3) compounds from oxalate by the pink-pigmented organisms occurs by a variant of the ;serine pathway' used by Pseudomonas AM1 during growth on C(1) compounds. 4. Evidence in favour of this scheme is provided by the finding that a mutant of Pseudomonas AM1 that lacks hydroxypyruvate reductase is not able to grow on oxalate.
