a single column cation exchanger resin was used to eliminate cations from renet cheese whey, with particular reference to the improvement of taste and flavor. ten panelists were convened to assess the contribution of the mineral components to the salty taste of whey, judging on the basis of taste, flavor and color. the organoleptic characteristics of untreated whey were arbitrarily assigned...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
a new type of cation-exchange nanocomposite membranes was prepared by in-situ formation of zno nanoparticles in a blend containing sulfonated poly (2,6-dimethyl-1,4-phenylene oxide) and sulfonated polyvinylchloride via a simple one-step chemical method. as-synthesized nanocomposite membranes were characterized using fourier transform infrared spectroscopy, scan...
KALCHEV, K., Y. RABADJIEV, D. GANCHEV, M. TSENOVA, I. ILIEV and I. IVANOVA, 2013. Study of proteases and protease inhibitors from Streptomyces strains. Bulg. J. Agric. Sci., Supplement 2, 19: 65–67 Proteases and protease inhibitors are important enzymes in Streptomyces physiology and differentiation. The objective of this paper was to investigate the optimal conditions for production of proteas...
In this study, the effect of different parameters such as time and temperature of calcination and milling on the formation of calcium aluminosilicates was investigated. Raw materials used in this study were calcium carbonate and kaolin in high purity. Powder X-ray diffraction patterns were obtained from all samples after heat treatment at various temperatures and times. To study the microstruct...
The aim of the study was to produce sensitive and specifi c polyclonal antibodies against somatotropin (ST) to be used for standardization of an ELISA to measure growth hormone (GH) level in serum and milk of lactating buffaloes. Recombinant bovine somatotropin (rbST), kindly donated by NHPP, California, USA was injected both in chicken and rabbit emulsifi ed with Freund’s complete adjuvant fol...
Bovine milk proteins has been widely studied because of the strong association and relationship with composition and technological properties of milk. Cow’s milk quality is very important, above all in such countries like Italy, where about 70% of whole milk production is used in cheese-making industry. A reversed-phase highperformance liquid chromatography (RP-HPLC) method was developed to ide...
Hunter syndrome or type II mucopolysaccharidosis is a rare lysosomal storage disease of X-linked recessive inheritance. It is characterized by a lack of the enzyme iduronate 2 sulfatase (I2S), which leads to the accumulation of glycosaminoglycans in many cells and tissues, resulting in myocardiopathy, airway obstruction, skeletal deformities, and severe and progressive neurologic disturbances. ...
A route for systematically accessing the oxo atoms of linear uranyl (UO22+) cation via cation–cation and halogen bonding interactions is detailed, interaction strengths are probed structural, vibrational, computational means.
