In Georgia, one of the most ancient vine-growing environment, the homemade production of wine is still very popular in every rural family and spontaneous fermentation of must, without addition of chemical preservatives, is the norm. The present work investigated the yeast biodiversity in five Georgian areas (Guria, Imereti, Kakheti, Kartli, Ratcha-Lechkhumi) sampling grapes and wines from 22 di...

A novel type of denitrifying bacterium (strain HxN1) with the capacity to oxidize n-alkanes anaerobically with nitrate as the electron acceptor to CO(2) formed (1-methylpentyl)succinate (MPS) during growth on n-hexane as the only organic substrate under strict exclusion of air. Identification of MPS by gas chromatography-mass spectrometry was based on comparison with a synthetic standard. MPS w...

A series of isoquercitrin (quercetin-3-O-β-d-glucopyranoside) esters with mono- or dicarboxylic acids was designed to modulate hydro- and lipophilicity and biological properties. Esterification of isoquercitrin was accomplished by direct chemoenzymatic reaction using Novozym 435 (lipase from Candida antarctica), which accepted C₅- to C12-dicarboxylic acids; the shorter ones, such as oxalic (C₂)...

nanocrystalline magnesium oxides were prepared by sol–gel method and were characterized by x-ray diffraction, n2-bet, sem and infrared spectroscopy techniques. the results confirmed the formation of nano- mgo materials with crystallite size in range of 5-20 nm and surface areas of 336-556m2/g. the product has been tested as destructive adsorbent for the decontamination of (2-chloroethyl) ethyl ...

abstract little information is available concerning morphological responses of lolium perenne cultivars (numan and speedy green) to salinity and trinexapac-ethyl treatment in initial growth. in order to evaluate the effect of salinity treatment (0, 2000, 4000 and 6000 mg/lit) and trinexapac-ethyl levels (0, 50, 100 gr/ha) on morphological responses of 'numan' and 'speedy green' in initial growt...

bermudagrass [cynodon dactylon (l.) pers.] is a perennial grass and has been long used as a medicinal herb in iranian traditional medicine to treat varied ailments. different parts of bermudagrass such as leaves, stolons, rhizomes and culms are rich sources of metabolites such as proteins, carbohydrates, mineral constituents, β-sitosterol, flavonoids, alkaloids, glycosides and triterpenoides. g...

A high-affinity iodinated agonist radioligand for the A2 adenosine receptor has been synthesized to facilitate studies of the A2 adenosine receptor binding subunit. The radioligand 125I-labeled PAPA-APEC (125I-labeled 2-[4-(2-[2-[(4- aminophenyl)methylcarbonylamino]ethylaminocarbonyl]- ethyl)phenyl]ethylamino-5'-N-ethylcarboxamidoadenosine) was synthesized and found to bind to the A2 adenosine ...

In this work, six different types of protic ionic liquids (PILs) have been studied. For all these PILs, the bacteria toxicity and environmental biodegradability investigated, as well their corrosive behavior miscibility in lubricating base oils. The PILs studied showed poor to moderate (BOD5/COD from 0.072 ± 0.002 0.18 0.01) slight (TU values between 1.18 0.04 2.7 0.1). However, properties are ...

H. G. BRAY, K. WHITE AND P. B. WOOD I955 3. Values for four apparent dissociation constants have been determined and the magnitude of another calculated. 4. Preliminary experiments have been performed on the inhibition of n-hexanamide hydrolysis by carboxylate ions other than n-hexanoate. 5. The effect of temperature on the hydrolysis has been studied: the apparent energy of activation is 10-5 ...
