  • System and method for defending against malicious software
    Patent number: 7085928
    Abstract: An execution management utility designed to prevent software from executing without the prior approval of system administrative or other security staff. For example, the present invention can assist corporations by enforcing policies regarding unauthorized, unlicensed, or pirated software, such as, but not limited to, games; entertainment software; and non-standard utilities, such as advertising-enhanced browsers. A Windows NT based system is disclosed in which a kernel module selectively intercepts process creation requests.

  • Transformation of sterols by fermentation
    Patent number: 4451564
    Abstract: This invention relates to a process for the preparation of a concentrate containing sterol compounds of natural origin, which concentrate is suitable as a starting material for the transformation of sterol compounds by fermentation, which comprises the steps of:(a) transesterifying distillation residues from the processing of natural fats and/or oils with a lower alcohol; and(b) subjecting the product of step (a) to molecular distillation to produce a main fraction having a content of up to about 50 percent by weight of sterol compounds.The invention also relates to sterol concentrates produced thereby and their transformation to valuable secondary products.

  • Process for the preparation of defective mutants of microorganisms
    Patent number: 4362815
    Abstract: For the production of 17-C-steroid-.alpha.-propionic acid compounds by microbial side chain degradation on 17-C-side chain steroid substrates wild strain microorganisms selected in predetermined manner are subjected to a multi-stage mutation and selection. The resultant mutant strains are capable of supplying the desired compounds, e.g. .DELTA.-4 BNC and/or .DELTA.-1,4 BNC in high yields even in the absence of inhibitors arresting the growth and/or degradation of the steroid ring. Wild strains and mutants particularly suitable, and their choice, production and use, are described.

  • Process for the production of a yeast autolysate
    Patent number: 4264628
    Abstract: A process for the production of a yeast autolysate consisting essentially of heating an aqueous suspension of live yeast cells to a temperature of from 20.degree. C. to 60.degree. C. for from 6 to 36 hours in the presence of from 0.03% to 15% by weight, based on the weight of the dry yeast mass, of a material selected from the group consisting of fatty acids having from 4 to 14 carbon atoms and their mono-, di- and tri-glyceride esters, separating the shells of the yeast cells from the liquid, evaporating said liquid and recovering a yeast autolysate.
