The biosynthesis of cell materials by Pseudomonas spp. growing on glycollate (Kornberg & Gotto, 1959, 1961), on glycine (Callely & Dagley, 1959), on oxalate (Quayle & Keech, 1959) or on other substrates catabolized to glyoxylate (Gray, Gerhart & Brooke, 1959) has been shown to be effected by a sequence of reactions in which, initially, glyoxylate is converted into glycerate. This transformation...

Background: Starch phase transition characteristics were studied by pre-treating starch samples in excess water, dilute sodium chloride and dilute sucrose solutions and subjecting them to differential scanning calorimetry (DSC). Unmodified maize, wheat and potato starches were held at specific temperatures between 30 and 90 °C for 30 min and promptly cooled to 25 °C. Treated samples were then a...

The nasal absorption of macromolecules from powder formulations and the effect of sodium carboxymethyl cellulose (CMC-Na) as a pharmaceutical excipient on their absorption were studied. Model macromolecules were fluorescein isothiocyanate-labeled dextran (average molecular weight of 4.4kDa, FD4) and insulin. The plasma concentration of FD4 after application of the powder containing 50% starch (...

A study was conducted to evaluate the main effects of dietary nitrate adaptation by cattle and alfalfa cell wall to starch ratio in in vitro substrates on nitrate disappearance and nitrite and volatile fatty acid (VFA) concentrations, as well as hydrogen (H2) and methane (CH4) accumulations. Rumen fluid from steers fed diets containing urea or nitrate was added into in vitro incubations contain...

“S INTRODUCTION The concentration of sodium metabisulfite (Na2S2O5) in an ECP-2 bleach accelerator sample is determined by a manual or potentiometric titration using an iodine (I3) titrant. In the method an excess of iodine is added to the sample. Sodium metabisulfite and Kodak persulfate bleach accelerator, PBA-1, present in the sample react with a portion of the iodine. The iodine that did no...

This study presents production of α-amylase by Aspergillus oryzae in solid-state fermentation using 14 agro-industrial wastes as substrate. Enzyme production was growth associated and maximum titers (15095 U/gds) were obtained after 72 h when incubated at 30°C on wheat bran (initial moisture content, 60%; initial medium pH, 5). Enzyme titers increased significantly when the solid medium was sup...

The aim and objective of orally disintegrating tablets by direct compression method was emerged from desired to provide patient with a conventional mean of taking their medication. Difficulty in swallowing (Dysphagia) is a common problem of all age groups, especially elderly and pediatrics, because of physiological changes associated with these groups of patients. In the present work Ondansetro...
