  • Identification, characterization, and application of sp. AL9:8 useful in microbially enhanced oil recovery
    Patent number: 7708065
    Abstract: The present disclosure relates to isolation, identification and application of Thauera strain AL9:8 which grows on crude oil as the sole carbon source under denitrifying anaerobic conditions Thauera strain AL9:8 can be used alone or in concert with other microorganisms to improve oil recovery, bioremediation of oil or hydrocarbons in contaminated soil, ground water or bodies of water, such as lakes, rivers or oceans and/or applying to method for promoting oil pipeline maintenance, removing a build up hydrocarbon on the intersurfaces of the pipeline.

  • Process for recombinant expression and purification of antimicrobial peptides using periplasmic targeting signals as precipitable hydrophobic tags
    Publication number: 20070122425
    Abstract: A process was developed for expressing antimicrobial peptides in a recombinant host cell that eliminates host cell toxicity and antimicrobial peptide degradation, as well as providing a process for rapid purification. Fusion proteins comprising a periplasmic targeting signal, cleavage site, and antimicrobial peptides provide the basis for this process which produces antimicrobial peptides that may be used in antimicrobial compositions and articles.
