| family spirosomaceae: gram-negative ring-forming aerobic bacteria. | the bacteria having a unique ring-like morphology first isolated from nasal mucus by weibel in 1887 were classified as a new genus spirosoma by migula in 1894. however, because these bacteria were not completely described for taxonomic purposes and their cultures were no longer available, the genus was deleted from the bergey's manual of determinative bacteriology, 6th edition, 1948. orskov (1928) created a new genus "microcyclus" (a name that has been found to be illegitimate and replaced with ... | 1990 | 2248690 |
| contributing carbohydrate catabolic pathways in cyclobacterium marinus. | the primary and secondary pathways of carbohydrate metabolism were determined in a nonfermentative gram-negative ring-forming marine bacterium, cyclobacterium marinus, by radiorespirometric studies. whereas glucose is oxidized mainly via the embden-meyerhof pathway, gluconate is catabolized mainly via the entner-doudoroff pathway, both in conjunction with the tricarboxylic acid cycle as a secondary pathway and with some participation of the pentose phosphate pathway. the operation of these contr ... | 1983 | 6848485 |
| a novel sulfonic-acid analogue of ceramide is the major extractable lipid of the gram-negative marine bacterium cyclobacterium marinus wh. | the extractable lipids of the gram-negative, sea-water bacterium cyclobacterium marinus strain wh contain about 94% of polar components which consist of two phospholipids, phosphatidylethanolamine (29% of the total lipids) and phosphatidylcholine (7%), and two phosphorus-free lipids. one of the latter has been shown to be a novel sulfonic-acid analogue of ceramide, 2-d-(2'-d-hydroxy-13'-methyltetradecanoyl) amino-3-d-hydroxy-15-methylhexadec-4 (e)-en-1-sulfonic acid (48%), and other is a lipodip ... | 1998 | 9518560 |
