temperature was 27°C. On International Streptomyces Project (ISP) media 1, 2, 3, and 5, the strain produced yellow diffusible pigment and the reverse side color of the colonies was yellow. Melanin production was not observed on either tyrosine or peptone iron agar. The following tests were positive: starch hydrolysis; degradation of allantoin, lecithin, pectin, xanthine, and hypoxanthine; resis...

Two strains of SporoboZomyces pecies, NRRL Y-6493 and NRRL Y-6502, produce extracellular, lightly acetylated, phosphorylated galactans when grown on media containing glucose as the carbon source. D-&lactose and D-galactose 6-phosphate were the only carbohydrate components present in strong acid hydrolysates. oc-D-Galactose 1 -phosphate was isolated after vigorous alkaline hydrolysis. Periodate ...

beta-D-Galactosidase (EC 3.2.1.23) was extracted from Streptococcus thermophilus grown in deproteinized cheese whey. Cultural conditions optimum for maximum enzyme production were pH 7.0, 40 degrees C, and 24 h. Proteose peptone (2.0%, wt/vol) and corn steep liquor (2.8%, wt/vol) were highly stimulatory, increasing the enzyme units available in their absence from 660 U/liter of medium to 18,200...

G. LaBella, K. Hughes Colorcon, Inc. Purpose To evaluate the influence of Starch 1500 on physical and chemical stability of a formulation containing a moisture sensitive active with a well characterized degradation pathway due to hydrolysis. Methods To fully assess Starch 1500 in a formulation versus a lactose based formulation currently on the market, three individual studies were conducted: 1...

Benchtop NMR systems offers various advantages such as being easy to use, not requiring constant maintenance and available at affordable prices. In this study, multiple aspects of benchtop spectroscopy were explored analyze milk in an industrial context, either regarding the quality production or differentiation final product. The first part focuses on conditions lactose hydrolysis quantitative...

BACKGROUND Thermophilic enzymes have attracted much attention for their advantages of high reaction velocity, exceptional thermostability, and decreased risk of contamination. Exploring efficient thermophilic glycoside hydrolases will accelerate the industrialization of biofuels and biochemicals. RESULTS A multifunctional glycoside hydrolase (GH) CoGH1A, belonging to GH1 family with high acti...
