  • Publication number: 20230013523
    Abstract: The present disclosure provides genetically modified microorganisms (e.g., bacteria or yeast) with enhanced mucin-binding and/or cell-adhesion properties. For example, the present disclosure provides bacteria exhibiting increased in vitro binding to Caco-2 cells, and increased in vitro binding to mucins. Such microorganisms (e.g., bacteria) can be used, e.g., to deliver bioactive polypeptides to the gastrointestinal tract of a mammalian subject. Modifying the microorganism in the described manner allows for the modulation of gastrointestinal retention and transit times for the microorganism (e.g., bacterium). Exemplary microorganisms (e.g., lactic acid bacteria, such as Lactococcus lactis) contain an exogenous nucleic acid encoding a fusion protein containing a cell-adherence polypeptide, such as CmbA, and a mucin-binding polypeptide, such as a trefoil factor (TFF), e.g., human TFF3. The current disclosure further provides method for making and using the described microorganisms (e.g., bacteria).

  • Patent number: 10793825
    Abstract: The present invention relates to gram positive bacteria with increased stress resistance and/or improved storage characteristics. In particular, the invention relates to gram positive bacterium which accumulate intracellular trehalose. The gram positive bacterium according to the invention lack cellobiose-specific PTS system IIC component (PtcC) activity. The gram positive bacterium may further lack trehalose 6-phosphate phosphorylase (TrePP) activity. The gram positive bacterium may further overexpress trehalose transporters. The invention further relates to compositions comprising such gram positive bacterium as well as methods and uses thereof.
