An enzyme in extracts of Aerobacter aerogenes was shown to catalyze the hydrolytic cleavage of cellobiose monophosphate (6-0-phosphoryl-b-D-ghtcopyranosyl-(1 --f 4)-D-gillcase) to yield equimolar amounts of D-glucose and D-glucose 6-phosphate. The enzyme was partially purified and characterized. In addition to cellobiose monophosphate, it catalyzed the cleavage of cellobiitol phosphate, arbutin...

room temperature. In plain broth there was surface growth, indicated by a whitish ring in contact with the glass, and a viscid sediment, partially disintegrating on shaking. In gelatine stab, growth occurred without liquefaction. Fermentation and biochemical reactions were as follows : No change in glucose, maltose, lactose, sucrose, mannitol or salicin. M.R. and V.P. reactions negative; no red...

Particle size reduction is effective in increasing the dissolution rate and bioavailability of poorly water-soluble drugs. However, obtaining microparticles without a distribution or even with narrow difficult conventional methods, such as milling antisolvent precipitation. In novel method used this study, uniformly sized droplets drug solution were first prepared on polydimethylsiloxane film, ...

Aspergillus terreus MS105 was originally isolated from soil and screened for cellulase production in the presence of various carbon sources including carboxymethyl cellulose (CMC), avicel, sigmacell, filter-paper and salicin. CMC induced the production of endoglucanase (EG) and filter-paperase while the levels of β-glucosidase (BGL) were increased when salicin was present in the medium. Nature ...

Apterous populations of Chaitophorous populicola Thomas (Homoptera: Aphididae) appear to track Eastern cottonwood (Populus deltoides Bartr.) leaf development. Few aphids occur onmature leaves.Marked individual aphids on leaves of different developmental stageswereobserved through a period of new leaf initiation. Nymph and adult C. populicola frequently track leaf development bymoving up to youn...

BACKGROUND During periods of human expansion into new environments, recognition of bitter natural toxins through taste may have conferred an important selective advantage. The G protein-coupled receptor encoded by TAS2R16 mediates response to salicin, amygdalin, and many bitter beta-glucopyranosides. beta-glucopyranosides are ubiquitous in nature, with many having a highly toxic cyanogenic acti...

Salicylate-containing herbs have been used as analgesic and anti-inflammatory remedies from ancient times. In this work we performed a comparative HPLC study of salicylic derivatives in three natural products: Salicis cortex, Populi gemmae and Ulmariae folium. We have identified and measured by a new, easy and fast HPLC method both salicylic acid and salicin, before and after acid hydrolysis, i...
