Showing papers on "Melibiose published in 1975"
TL;DR: The analysis of saccharides by liquid chromatography on an automated instrument is described in this paper, where conditions for the resolution and quantification of fructose, glucose, sucrose, melibiose, raffinose, betaine and three kestose isomers as well as starch hydrolysates are given.

TL;DR: Evidence obtained from hapten inhibition experiments indicated that the precipitin that reacts with pneumococcus type XIV polysaccharide can be inhibited by a number of simple sugars, and the combining sites of the lectin appear to be most complementary to 2-acetamido-2-deoxy-D-galactopyranosyl residues, probably in beta linkage.
28 citations
TL;DR: According to the CD results, the polypeptide chain backbone in the lectins was not affected by the saccharides, whereas significant disorganization occurred in 7 m guanidine-HCl.

TL;DR: The diversity in properties indicates that the cultural reactions do not permit definitive characterization or speciation, and it is suggested that the S. faecium-like strains have provided the ancestral pool from which the species as now described has become adapted to life within the animal host.
Abstract: The unidentified streptococci from plants are catalase negative, gram positive, usually lanceolate cells occurring in pairs and short chains. More than one-half of the 505 strains investigated conform generally to the description of Streptococcus faecium, but many deviate in one or more of Sherman's characteristics, growth on bile-esculin agar, and acidification of milk. A few strains superficially resemble Streptococcus lactis. The strains not termed S. faecium-like are heterogeneous in adherence to Sherman's characteristics, growth and pigmentation on tellurite and tetrazolium agars, and the heme peroxidase reaction; 35 fermentation patterns were established from the fermentations of arabinose, raffinose, melezitose, melibiose, mannitol, and sorbitol. The diversity in properties indicates that the cultural reactions do not permit definitive characterization or speciation. It is suggested that the S. faecium-like strains have provided the ancestral pool from which the species as now described has become adapted to life within the animal host.

TL;DR: Six texts of assimilation used in the taxonomy of yeasts have been critically tested and it is indicated that cellobiose, lactose, maltose and trehalose tests no longer supply an important value for the speciation, because the number of cryptical osidases is so high.
Abstract: Six texts of assimilation used in the taxonomy of yeasts, (lactose, maltose, cellobiose, trehalose, melibiose, sucrose) have been critically tested by the examination of intracellular enzymic systems. The results obtained among the sporogenous species ofSaccharomyces, Kluyveromyces, Pichia, Hansenula, Debaryomyces indicate that cellobiose, lactose, maltose and trehalose tests no longer supply an important value for the speciation, because the number of cryptical osidases is so high.

TL;DR: By gas chromatography of trimethylsilylated derivatives of sugars, trehalose has been shown to be the main disaccharide in wines; its amount can reach 600 mg/l.
Abstract: By gas chromatography of trimethylsilylated derivatives of sugars, trehalose has been shown to be the main disaccharide in wines; its amount can reach 600 mg/l. Other disaccharides identified (sucrose, isomaltose, lactose and turanose) are present in small amounts, seldom above 50 mg/l, sometimes below 5 mg/l. Traces of melibiose and gentiobiose are possible. Conditions of trehalose formation by yeast during fermentation are described. Also technological applications of these results are discussed.

TL;DR: The attack of chitin, melibiose and amygdalin can be used for the differentiation of some species, and most of the enzymes studied here, although Tween-esterase and DNase are often present in the majority of the isolates.
Abstract: In addition to previous taxonomic work, eight biochemical tests have been applied to the study of 580 Bacillus strains belonging to 22 species. The attack of chitin, melibiose and amygdalin can be used for the differentiation of some species. It is the same with most of the enzymes studied here, although Tween-esterase and DNase are often present in the majority of the isolates. RNase is still more frequent, being found in nearly all the strains. On the other hand, arginin-dihydrolase appears to be very rare and ornithin-decarboxylase seems always absent.
