标 题:Combinatorial organic synthesis of unique biologically active compounds
发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

摘要:The invention relates to a strain of Trichoderma harzianum Td50b, deposited with the deposit number NCAIM (P) F 001412, which produces the exohydrolases involved in the degradation of plant material and presents antagonism against pathogens of ornamental crops, including through synthesis of odorant volatile compounds with antifungal activity. The strain was used to produce a controlled release compositions that promote the colonization of the material intended to be composted, assuring the survival of propagules not-liberated after the initial colonization of the substrate with the strain producing fungistatic volatiles compounds, including for the dormant propagules of the same strain, and, on the end, accelerate the obtainment process of composts intended to be used for mulching of the ornamental crop soil, in order to protect them against the attack of pathogen agents.

权利人:KAO CORP
摘要:A mutant of an extracellular enzyme-producing microorganism belonging to genus Bacillus, which is resistant to a cell membrane synthesis inhibitor, including vancomycin and ristocetin, is disclosed. The cell membrane synthesis inhibitor-resistant mutant can produce such an enzyme as cellulase, protease, or amylase about 2 to 4 times of the parent strain. Such a mutant can be produced by subjecting an extracellular enzyme-producing microorganism tot a mutation treatment, and culturing said microorganism in a culture medium containing a cell membrane synthesis inhibitor.

摘要:Disclosed in the present invention is a genetically-engineered Yarrowia lipolytica strain highly producing carotenoids, which is obtained by constructing a xylose-induced activation system in the genetically-engineered Yarrowia lipolytica strain XK17 to control the induced expression of critical enzymes for synthesis of astaxanthin, wherein the critical enzymes for synthesis of astaxanthin comprise β-carotene hydroxylase CrtZ and β-carotene ketonase CrtW. Further disclosed in the present invention is the use of the genetically-engineered Yarrowia lipolytica strain in fermentation production of carotenoids. The present invention starts from the Yarrowia lipolytica strain XK17 highly producing β-carotene, and uses the xylose-induced activation system to separately control the expressions of the β-carotene hydroxylase (CrtZ) and β-carotene ketonase (CrtW) or only control the expression of the CrtW or the CrtZ, thereby separately achieving highly producing astaxanthin, or canthaxanthin, or zeaxanthin under the functions of a proper xylose induction concentration and induction opportunity.
