  • 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: 4415662
    Abstract: Crude petroleum and petroleum products such as encountered in land or sea-borne spills are degradated by contact with the microorganism, Actinomucor elegans (Ediam) Benj. and Hasselt, Strain No. TC-405, ATCC 20613, or an enzymatic active material obtained therefrom. The microorganism and enzymatic active material may be used in combination with a carrier and/or detergent. 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: 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.
