  • Patent number: 4673687
    Abstract: A chemotherapeutic composition for the control of plant diseases caused by mycoplasma-like organisms, rickettsia-like organisms, or seed-borne legume viruses. The composition is composed essentially of the tannate complex of picro ammonium formate combined with a minor amount of a surfactant sufficient to prevent formation of ammonium picrate. The preparation and use of the composition are disclosed. Also disclosed is a related chemotherapeutic composition for the control of plant diseases caused by plant pathogenic fungi and bacteria and composed essentially of a tannate complex of picro cupric ammonium formate in aqueous solution combined with a minor amount of a surfactant sufficient to prevent formation of ammonium picrate, along with its method of preparation and manner of use.
    Type: Grant

  • Patent number: 4415661
    Abstract: Crude petroleum and petroleum products such as encountered in land or sea-borne spills are degradated by contact with the microorganism, Geotrichum marinum Thirumalachar sp nov., ATCC 20614, or enzymatic active material obtained therefrom. The microorganism and enzymatic active material may be used in combination with a carrier medium. The microorganism and enzymatic active material are effective for degradation in inhospitable climates and various land and open water conditions, generate no deleterious products or chemicals, and are long-acting and rapid in onset of initial activity.

  • Patent number: 4288546
    Abstract: A new system of serially culturing anterior pituitary gland cells in a new nutrient medium under open aeration to produce large amounts of pituitary hormones. Using the new system of culture and new nutrient media, the pituitary cells can be grown in vitro to produce in approximately three weeks 10 to 12 times the amount of extractable hormone originally present in the original tissue.

  • Patent number: 4124448
    Abstract: A new system of serially culturing human anterior pituitary gland cells in a new nutrient medium to produce large amounts of human growth hormone. Since only human growth hormone can be used to treat growth deficiencies in man, there is a great demand for the hormone, which is in relative short supply since only 2 to 3 mgs. of the human growth hormone can be extracted from one human pituitary gland obtained at autopsy. Using the new system of culture and new nutrient media, the human pituitary cells can be grown in vitro to produce in approximately three weeks, more than 20 times the amount of extractable growth hormone than that which was originally present in the original tissue now used for extracting the 2 to 3 mgs. of the hormone.

  • Patent number: 4082613
    Abstract: A process for the production of insulin using fungal cells. Human insulin producing cells are extracted to obtain the functional genome (the genetic material which determines the capacity of the cells to produce insulin) which is used to transform fungal cells, making them capable of producing insulin. The insulin has been extracted and identified by radioimmune assay and by bioassay. The same process can also be applied to produce animal insulins using specific specie transforming functional insulinogenic genomes. A process for serial secondary culture of insulin producing cells is disclosed. The significance of the invention is related to the great need to produce human insulin in large amounts. Human insulin has distinct biological and clinical advantages when compared with commercially available animal insulins now used for the treatment of diabetes mellitus in man.
