Composition of Extracellular Polymeric Substances (EPS) produced by Flavobacterium columnare isolated from tropical fish in Brazil

Thirty nine isolates of Flavobacterium columnare from Brazilian fish farms had their carbohydrate composition of EPS evaluated by high efficiency liquid chromatography, using the phenol-sulfuric acid method of EPS. The occurrence of capsules on F. columnare cells was not directly related to biofilm formation, and the predominant monosaccharide is glucose.

Modification of carbohydrate compositions of 31/36 kDa proteins of plerocercoids (sparganum) of Spirometra mansoni grown in different intermediate hosts

We purified specific 31/36 kDa antigenic molecules from sparganum in different intermediate hosts (snakes and mice) and analyzed their monosaccharide compositions. Compositional analysis showed that glucose and mannose concentrations were 2-3 fold higher in the 31/36 kDa molecule purified from snakes than those from mice. This result implies that antigenic glycoproteins of sparganum from snakes might be modified in mammalian sparganosis with respect to their carbohydrate composition.

Chemical composition of drug legume seeds grown in three different countries

Dry mature seeds of fourteen cultivars or lines of legumes produced in three different countries were compared with respect to their mono and oligosaccharide contents in an attempt to determine the possibilities for selection in a breeding programme on the basis of some chemical characteristics. Materials were obtained from legume production areas in Egypt, U.S.A. and India. Egyptian legumes included Faba bean [Giza 2], Mung bean [T 44]. Soybean [Crowford], Pea-nut [Giza 5] and Lentil [Giza 9]. The American legumes were Faba bean, Navy bean, Soybean, Kidney bean, Black eye peas and lentils. The Indian legume included pengel gram, Red gram and Green gram. The determination of total dietary fiber [TDF] of the whole dry seed range from 5.5% to l3.2% for Egyptian legumes and from 7.73% to 17.95% for American legumes, in case of Indian legumes range from 6.13% to 13.67%. The rafinose content of the whole dry seed range from 0.11% to 0.44% for Egyptian legume, from 0.11% to 1.35% for American legumes and from 0.36% to 0.53% for Indian legumes on dry matter basis, while sucrose range from 1.3% to 1.8% for American legumes, from 1.3% to 1.5 for Indian legumes and from 0.96% to 2.09% for Egyptian legumes

Açúcares do mel: aspectos analíticos / The sugar of honey: analytical aspects

Os açúcares glicose e frutose, juntamente com a água perfazem cerca de 85 por cento da composiçäo do mel, sendo que os únicos monossacarídeos säo a glicose e a frutose, que säo ligadas através de açäo enzimática para dar origem a uma série de oligossacarídeos. A análise de açúcares do mel é objeto de estudo há mais de um século, e várias metodologias sao empregadas com este fim.
