Transglycosylation by Glycosidase in Aqueous-Organic Solvent System.

Heck reaction catalyzed by Pd/C, in a triphasic-organic/Aliquat 336/aqueous-solvent system.

The rate of the Pd/C catalyzed Heck coupling of Ar-I with CH(2)=CH-R is accelerated tenfold by the presence of Aliquat 336 (A336), a well known phase transfer catalyst, and an ionic liquid. Both when conducted in A336 as solvent, and in an isooctane/A336/aqueous triphasic mixture, the Heck reaction of aryl iodides with electron deficient olefins, catalyzed by Pd/C, proceeds with high yields and...

Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System

Poly(adenosine diphosphate ribose) polymerase purification in an aqueous/organic-solvent system [proceedings].

plasmid DNA. Those fragments represent the homologous Ti-plasmid DNA segment 8,um long (1 5 % of the Ti-plasmid). An argument that this region of the plasmid contains genes essential for the expression of oncogenicity came from the analysis of a deletion mutant in the Ti-plasmid (Hernalsteens et al., 1975). Since this deletion mutant is unable to confer oncogenicity and has lost exactly those t...

Enhancement of Palmarumycin C12 and C13 Production by the Endophytic Fungus Berkleasmium sp. Dzf12 in an Aqueous-Organic Solvent System.

The endophytic fungus Berkleasmium sp. Dzf12, isolated from Dioscorea zingiberensis, was found to produce palmarumycins C12 and C13 which possess a great variety of biological activities. Seven biocompatible water-immiscible organic solvents including n-dodecane, n-hexadecane, 1-hexadecene, liquid paraffin, dibutyl phthalate, butyl oleate and oleic acid were evaluated to improve palmarumycins C...
