  • Patent number: 6132985
    Abstract: The present invention describes methods for the detoxification of a mixture of nitrile compounds, or a mixture of nitrile and amide compounds by conversion of the nitrile compound(s) to the corresponding amide or acid compounds using a pure culture of an induced microorganism strain capable of converting a nitrile moiety to an amide or acid moiety. If an amide is formed or is present in the mixture, the amide can be further converted, using the present methods for detoxification, to the corresponding acid. The acid can then, if desired, be further degraded to CO.sub.2, H.sub.2 O and biomass. The induced pure cultures are able to detoxify a mixture of nitriles or a mixture of nitrites and amides which are typically present, in high concentration(s), in nitrile production waste streams.

  • Patent number: 5866354
    Abstract: A method of identifying highly fecund males in which an isotonic, buffered liquid test specimen of semen is layered on top of a barrier medium that inhibits net movement (migration) of less mobile sperm into the barrier medium. Differences in mobility of populations of sperm among test subjects have been found to predict whether a male will be highly fecund or not. Sperm migration into the barrier medium is quantitated, for example by analyzing the barrier medium in a spectrophotometer or a photometer after sperm migration is allowed to occur. Alternatively, a collection member coated with a sperm binding protein may be placed below the barrier medium, and the number of sperm that bind to the collection member quantitated after incubation. The invention also includes a device for incubating the barrier medium at a physiologic temperature for a sufficient period of time to allow the highly mobile sperm to migrate into the barrier medium.

  • Patent number: 5128471
    Abstract: The present invention relates to a process for the production of primary amines containing aliphatically or cycloaliphatically bound amino groups, characterized in that the isocyanate groups of organic isocyanates containing aliphatically and/or cycloaliphatically bound isocyanate groups are formylated with formic acid in a first reaction step and the N-formyl groups are subsequently converted into amino groups.The present invention also relates to polyamine mixtures obtained by this process and containinga) about 40 to 90% by weight, based on the total weight of components a) and b), of N,N',N"-tris-(6-aminohexyl)-isocyanurate andb) about 10 to 60% by weight, based on the total weight of components a) and b), of higher homologs of this triamine containing more than one isocyanurate ring.Finally, the present invention relates to the use of these polyamine mixtures as hardeners for polymer precursors containing epoxide or isocyanate groups.
