Nutritional factors influencing the polysaccharide production of Brucella suis.
The formation of cellular polysaccharide by cells of the genus Brucella has been reported by several investigators: Favilli and Biancalani (1934), Higginbotham and Heathman (1936), and Libby and Joyner (1941). These workers, however, dealt mainly with the immunological characteristics of the polysaccharide, and little emphasis was placed upon the nutritional conditions affecting its production....
متن کاملStudies of sulfur metabolism of Brucella suis.
Those chemically defined media which have been proposed for cultivation of Brucella vary widely, both qualitatively and quantitatively, with respect to their content of sulfur compounds (McCullough and Dick, 1943; McCullough et al., 1947; Gerhardt and Wilson, 1948; Rode, Oglesby, and Schuhardt, 1950). Since the early studies of Zobell and Meyer (1932) there has been no critical investigation of...
متن کاملCellular fatty acids of Brucella canis and Brucella suis.
The cellular fatty acid composition of Brucella canis and Brucella suis was determined by gas-liquid chromatography. The presence of relatively large amounts of a 19-carbon cyclopropane fatty acid in B. suis was a major distinguishing feature between these organisms. The gas-liquid chromatography test for cellular fatty acids provides an additional criterion for the distinction of antigenically...
متن کاملStudies on the nutritional requirements of the fusobacteria. II. Requirements for pantothenate and purines.
In a previous study on the nutritional requirements of Fusobacterium nucleatum it was reported that growth factors were present in yeast extract for these microorganisms (Omata, 1953). Further studies were made to elucidate the nature of these growth factors in a simplified medium under different environmental conditions. In this present study it has been found that pantothenic acid, tryptophan...
متن کاملStudies on nutritional requirements of Pseudomonas aeruginosa for lipase production
A nutritional requirement for the lipase production by Pseudomonas aeruginosa strain was investigated. The bacterial strain was isolated from municipal sewage and it was culture with different nutritional composition. The maximum lipase activity was obtained with maltose as the sole carbon source 6.5 Uml, followed by lactose 4.6Uml . The various salts used the best results were observed with ca...
