Abstract: The present invention relates to a post extraction process for preparing low acyl gellan, comprising the steps: deacylation treatment of gellan gum-containing fermentation broth, enzyme treatment, flocculation of low acyl gellan gum with divalent or polyvalent metal cations, clarification treatment of gellan gum solution, dehydration treatment of gellan gum solution, removal of divalent or polyvalent cations and decoloration, and drying and milling. Preferably, the process comprises the step of formulating a proper amount of chelating agent/acid system before the drying and milling step to chelate the added additional divalent cations added during the use of gellan gum, and at the same time to keep the pH value in a relatively stable condition. The present invention also provides the various low acyl gellan gums prepared by the above methods. The product has the following characteristics: a good appearance, a high transmittancy, and high gel strength.

Abstract: The reversing handle structure according to the present invention includes: a handle and a handle seat. A mounting hole is formed at the end of the handle and the mounting pivot is assembled with the handle seat. The mounting hole can be set into the mounting pivot so as to assemble the handle with the handle seat. Herein, the mounting pivot has a symmetrical shape along its long axis. The size of the mounting hole is corresponding to that of the mounting pivot. The mounting hole is set into the mounting pivot of the handle seat before or after the handle is reversed horizontally. The reversing handle structure according to the present invention is adapted to various door structures which have different open directions, which can greatly facilitates the users.

Abstract: A neutral templating route to mesoporous molecular sieves based on H-bonding and self-assembly between neutral primary amine or diamine surfactants (S°) and neutral inorganic precursors (I°) has been used to prepare hexagonal and lamellar mesoporous silicas with site isolated transition metal centers. This templating approach allows for the preparation of hexagonal or hexagonal-like mesoporous oxidation catalysts with large framework wall thickness of at least about 17 Å, small elementary particle size (≦400 Å), and unique combinations of framework-confined mesopores and textural mesopores while at the same time providing for facile recovery of the neutral template by simple solvent extraction.
