权利人:UNIV SOUTH CHINA TECH
摘要:A yeast strain and a method for the synthesis of 2,5-dihydroxymethylfuran using this strain are disclosed. The yeast strain is Meyerozyma guilliermondii SC 1103, which has been maintained in the China Center for Type Culture Collection (CCTCC, Wuhan, P.R. China) with an access No. of M2016144. The method for the synthesis of 2,5-dihydroxymethylfuran using this strain is described as follows: after pre-cultivation and cultivation, Meyerozyma guilliermondii SC 1103 cells are added into the buffer solutions containing 5-hydroxymethylfurfural and glucose; the biocatalytic reaction is conducted under designated conditions, thus affording 2,5-dihydroxymethylfuran. This disclosure has many advantages such as good selectivity, mild reaction conditions, environmental friendliness, high efficiency, and good yield.

摘要:The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The modular synthesis of tetracyclines and tetracycline analogs described provides an efficient and enantioselective route to a variety of tetracycline analogs and polycyclines previously inaccessible via earlier tetracycline syntheses and semi-synthetic methods. These analogs may be used as anti-microbial agents or anti-proliferative agents in the treatment of diseases of humans or other animals.

摘要:The invention relates to a process for performing a aqueous synthesis of titanium phosphates (TiP) having solely —H2PO4 groups, which process is characterised by the following steps: providing titanium (IV) oxysulphate, TiOSO4, in an aqueous solution or in a powder and H2SO4, substantially without transition divalent metal ions, including cobalt (II) and copper (II), heating of the thus formed aqueous solution to above 50° C., but below 85° C. for at least 30 minutes, providing a controlled amount of H3PO4 to said aqueous solution, to form an aqueous solution containing a molar ratio between TIO2 and P2Os being controlled to about 1:1, not above 1:1.5 and not below 1:0.7, stirring the thus formed aqueous solution for at least 3 hours to form precipitates of titanium phosphate, and allowing ageing of said solution, without stirring, acidic washing of the formed precipitate using HCI or other acids to obtain TiO(OH)(H2PO4)-H2O having solely —H2PO4 ion-exchange chemical groups and allowing said precipitates to dry to a powder product, substituting protons in the powder product TiO(OH)(H2PO4)-H2O to sodium cations by treatment of the latter with solutions of sodium carbonate and allowing the thus formed powder of Na—TiP1 to dry.

发明人：BEAUPREZ JOERI; DECOENE THOMAS; VERCAUTEREN ANNELIES
权利人:INBIOSE NV
摘要:The present invention is in the technical field of synthetic biology, metabolic engineering and cell cultivation. The invention provides a cell for production of a disaccharide and/or an oligosaccharide like a milk oligosaccharide wherein synthesis of UDP-N-acetylglucosamine in said cell is rendered less functional. The invention further provides use of said cell in a cultivation or incubation. The invention also describes methods for the production of a disaccharide and/or an oligosaccharide like a milk oligosaccharide using said cell as well as the purification of said disaccharide and/or oligosaccharide like a milk oligosaccharide.
