Glucosidase was immobilized by microencapsulation using interfacial crosslinking, and employed in the biosynthesis of alkylglucoside.

The method of immobilization of glucosidase using absorption, the technology of enzymatic synthesis of alkylglucosides using free and immobilized glucosidase were introduced; In an enzymatic synthesis of alkylglucosides, the water content has important effect on reaction rate, the optimum water content is about 8%～10%.

MEG (Methylglucoside) is a chemical derivative of glucose, it can form semipermeable membrane and reduce the activity of water when it is added into the drilling fluid, so it can stabilize wellbore by controlling the movement of water.

Anti-sloughing water-based drilling fluid systems for offshore drilling developed since the 1990s,including silicate system,formate system,methylglucoside system and polyols system.

A new glucoside, fastigitin A (1), namely 2-O-β-D-glucopyransyl-3-methyl-methyl pinalate, together with twelve known constituents (2-13), was isolated from the root of Rhodiola fastigiata (Hook.
