2-Deoxy-D-lyxo-hexonic acid from 2-deoxy-D-lyxo-hexose by Pseudomonas aeruginosa fermentation

Folia microbiologica. 1979 ; 24 (2) : 185-7.

Aerobic fermentation of media or solutions containing 2-deoxy-D-lyxo-hexose and calcium carbonate by bacterial cells capable of oxidizing aldoses to aldonic acids was used to prepare 2-deoxy-D-lyxo-hexonic acid; the acid was isolated in a 62% yield in the form of its 1,4-lactone.

Biochemical dehydrogenations of saccharides. IX. D-lyxo-5-hexulosonic acid from D-mannose by Acetomonas oxydans fermentation

Folia microbiologica. 1977 ; 22 (5) : 373-5.

Folia Microbiol (Praha)
ISSN 0015-5632
Zdroj

Fermentation of nutrient media by a selected strain of Acetomonas oxydans with a continuous pH control gave D-lyxo-5-hexulosonate in the form of a calcium or potassium salt with a yield equal to 95% of theory. The media contained up to 20 g D-mannose per 100 ml and a small amount of a readily assimilated monosaccharide.

5-Deoxy-5-fluoro-L-sorbose originating from 2-deoxy-2-fluoro-D-glucitol by fermentation with Acetomonas oxydans

Folia microbiologica. 1977 ; 22 (4) : 295-7.

Zdroj

Using fermentation with a selected strain of Acetomonas oxydans it was possible to convert 2-deoxy-2-fluro-D-glucitol to 5-deoxy-5-fluoro-L-sorbose, in agreement with Bertrand's and Hudson's rule. The last-named compound was isolated in a yield of 88%. Both compounds were little toxic against Acetomonas oxydans.

Biochemical dehydrogenations of saccharides. VII. 2-Deoxy-D-gluconic acid from 2-deoxy-D-glucose

Folia microbiologica. 1975 ; 20 (5) : 409-11.

Zdroj

Fermentation of a medium containing 5% 2-deoxy-D-glucose and barium carbonate by a strain of Pseudomonas aeruginosa yielded barium 2-deoxy-D-gluconate. The yield was 77% theoretical. The strain in question makes it possible to prepare directly calcium, magnesium, manganese and ferrous salts of 2-deoxy-D-gluconic acid. A treatment of 5% solution of 2-deoxy-D-glucose with commercial glucose oxidase preparation caused also a complete dehydrogenation.
