  • Chemiluminescence immunoassay for chlorinated aromatic compound detection
    Patent number: 5580741
    Abstract: A sensitive chemiluminescence immunoassay method for field detection of the presence or the amount of low chlorinated biphenyl compounds in a solution is disclosed. The assay has a five minute analysis time and a working range of detection as low as about 1 part per billion chlorinated biphenyl. Kits for the detection of chlorinated biphenyls are disclosed.

  • 2',4,4"-m-terphenyltriols and fungal strain used to make same
    Patent number: 5105025
    Abstract: A. parasiticus is employed to hydroxylate 2'-hydroxyterphenyl compounds to terphenyltriols, which can be used to form branched polycarbonates. The hydroxylation reaction is enhanced by maintaining a sufficient amount of a carbon source in the culture medium-reaction medium to maintain the ammonium level below 300 ppm. during the bioconversion phase. Employment of a mutant strain of A. parasiticus which was isolated following ultraviolet light mutagenesis to reduce its tendency to produce aflatoxins is preferred.
