Abstract: Isolates of Serratia marcescens such as Serratia marcescens MSU-97 and serratamolide are useful to protect plants from Oomycete pathogens.

Abstract: Oocydin A is a mono-chlorinated lipophilic macrocyclic lactone that was isolated from a strain of Serratia marcescens that produces oocydin A in culture. Oocydin A has a molecular mass of 470, contains one atom of chlorine, a carboxyl group, and a tetrahydrofuran ring internal to a larger macrocyclic ring. Minimum inhibitory concentrations of circa 0.03 &mgr;g ml−1 were noted for oocydin A against phytopathogenic Oomycetes.

Abstract: Taxol is produced from taxol-producing micro-organisms. Methods of obtaining the taxol-producing microorganisms are described. Radioactive labelled taxol products and methods for use of the radioactive labelled taxol and for the treatment of leukemia and cancer cells are described.

Abstract: The present invention is directed to a family of unique antimycotic lipopeptide compounds produced by Pseudomonas viridiflava. The lipopeptides are effective against both human and plant fungal pathogens, and are typically characterized by their ability to inhibit growth of Candida albicans. Representative lipopeptides of the invention have molecular weights of 1137, 1153, 1164 and 1181 daltons.

Abstract: Peptide antimycotics, termed pseudomycins, display broad spectrum antibiotic activity, and in particular are highly effective, non-toxic antibiotics against fungal pathogens of human and animal disease. The peptide antimycotics (pseudomycins) may be used in the treatment of the fungal pathogen Candida albicans. Also disclosed is a method of purification and isolation, including characterization, of the pseudomycins.

Abstract: An immunosuppressant compound is produced having the structure: ##STR1## or a mirror image thereof, wherein X.sub.1 is 2,2-dimethylvinyl and X.sub.2 and X.sub.3 together are .dbd.CH.sub.2 ; or X.sub.1 is 2,2-dimethyloxiranyl, and X.sub.2 and X.sub.3 together are --0--CH.sub.2 --; or X.sub.1 is 1,2-dihydroxy-2-methyl-propyl, X.sub.2 is --CH.sub.2 OH, and X.sub.3 is OH; or X.sub.1 is 2-hydroxy-2-methylpropyl, X.sub.2 is H, and X.sub.3 is CH.sub.2 OH; or X.sub.1 is COOR, and X.sub.2 and X.sub.3 together are .dbd.O, where R is a lower alkyl, phenyl, or benzyl group; or X.sub.1 is 2-methylpropyl, X.sub.2 is H, and X.sub.3 is CH.sub.3. The compound can be produced by culturing Fusarium subglutinans f. sp. tripterygii ATCC 74358 isolated from the stems of Tripterygium wilfordii. A pharmaceutical composition for immunosuppression therapy is prepared containing the compound and a pharmaceutically acceptable vehicle.

Abstract: Taxol and radiolabelled taxol are produced from sterilized Yew trees by contacting sterilized Yew tree stock with a reactor solution comprising a reducing agent, an energy source, a buffer to maintain pH in the range of 6.5 to 7.5, a taxol precursor, and a steroid inhibitor. A radiolabelled precursor may be included in the reactor solution to produced radiolabelled taxol.

Abstract: Taxol and radiolabelled taxol are produced from sterilized Yew trees by contacting sterilized Yew tree stock with a reactor solution comprising a taxol precursor under a reducing environment. The reactor solution may also contain a reducing agent, an energy source, a buffer to maintain pH in the range of 6.0 to 8.0, and a steroid inhibitor. A radiolabelled precursor may be included in the reactor solution to produced radiolabelled taxol.

Abstract: Taxol is produced from a taxol-producing microorganism Taxomyces andreanae BS 279.92. Radioactive taxol products and methods for use of the radioactive labelled taxol are described.

Abstract: A method of selectively inducing chlorosis on a knapweed plant while spar other plants comprises applying a knapweed phytotoxic amount of the L,L isomer of the cyclodipeptide of the invention to a field at a period in time prior, during or subsequent to the emergence of the plants; and allowing for the cyclodipeptide to remain in contact with the plants for a period of time effective to attain the phytotoxic effect.

Abstract: Beneficial growth of roots in dicotyledonous plants is achieved by genetic transformation with root-inducing A. rhizogenes, preferably the novel strain A. rhizogenes ATCC 39207. The A. rhizogenes not used to transform the plant is reduced to noninfective levels with A. radiobacter, preferably A. radiobacter K-84.

Abstract: A novel agriculturally useful composition that includes a seed treated with selected infectivity-cured Hr plasmid-bearing microorganism. Also provided are methods of enhancing root elongation, shoot elongation or root development of selected seeds. These methods include treating a selected seed with the infectivity-cured Hr plasmid-bearing microorganism. In addition, there is provided a method of inducing germination of grass seed that involves treating a grass seed such as Kentucky bluegrass seed with a selected infectivity-cured Hr plasmid-bearing microorganism. Furthermore, there is provided a method of promoting plant growth at a lower soil temperature than is common at the time of planting a seed of the plant. Additionally, there is disclosed an inoculant for increasing nodulation, root mass and shoot mass in a leguminous plant. The inoculant contains a Rhizobium microorganism and a selected infectivity-cured Hr plasmid-bearing microorganism.
