  • Biologically pure culture of yeast strain used for the microbial detoxification of xenobiotics
    Patent number: 4968620
    Abstract: A strain of symbiotic yeast NRRLY-18546 from the cigarette beetle (Lasioderma serricorne) has been discovered, which is capable of detoxifying a variety of zenobiotics including insecticides, herbicides, mycotoxins, and plant toxins (allelochemicals). Thus, compositions of the yeast provide a biological alternative to chemical detoxification of xenobiotics.

  • Kojic acid and esters as insecticide synergists
    Patent number: 4956353
    Abstract: Kojic acid and its esters have been found to be more effective synergists for pyrethroid and carbamate insecticides on H. zea and S. frugiperda. Thus they may serve as replacements for the widely used methylene dioxyphenyl compounds such as piperonyl butoxide.
