  • Extraction of nitrogen from organic materials through ammonification by mixed bacterial populations
    Patent number: 9809795
    Abstract: The invention provides a process for producing ammonia or ammonium from an organic material by fermenting a medium comprising organic material in the presence of a mixed bacterial population capable of ammonification, wherein the fermenting is under conditions, and for a sufficient period of time, to produce a fermentation product that comprises ammonia or ammonium. The organic material includes nitrogenous compounds suitable for conversion to ammonia or ammonium.

  • Modified beta-lactamase and method for its preparation
    Patent number: 7989192
    Abstract: The invention relates to targeted post translational modification of metallo-beta-lactamase by truncation and insertion of a dipeptide at the amino terminal end to reduce amino terminal heterogeneity in a recombinant DNA production system. A protein K-T-E-?BL is expressed, and modified by host proteases to E-?BL. Appropriate nucleotide molecules, vectors and hosts are also described. E-?BL is useful in a pharmaceutical composition for treating antibiotic induced adverse effects in the intestine of patients treated with beta-lactam antibiotics.
