Abstract: The invention encompasses compositions, kits and methods for modifying bacteria, preferably naturally occurring bacteria, in situ. These can be used to treat, prevent or cure microbiome-associated diseases or disorders by modulating the molecules expressed and/or secreted by bacterial populations of the microbiome in a specific manner.

The compositions, kits and methods of the invention do not result in the direct death of these populations or a direct significant inhibition of their growth. The invention further includes methods for screening for genetic modifications in the bacteria, for determining the efficiency of vectors at inducing these genetic mutations, and for determining the effects of these mutations on bacterial growth.

The fermentation broth of this Streptomyces has an epirubicin potency of up to 102.0 ?g/ml.

Abstract: This invention is directed to pancreatic enzymes that have been charged with zinc ions, or zinc-charged pancreatic enzymes. Charging the pancreatic enzymes with zinc ions activate the pancreatic enzyme's anticancer and anti-inflammation properties and make the enzymes capable of being administered orally. It is observed that the zinc-charged pancreatic enzymes are able to induce apoptosis in various cancer cells without affecting the normal cells. The zinc-charged pancreatic enzymes have also been observed inducing apoptosis in trophoblasts and reducing inflammation in general. This invention is further directed to a method of preparing zinc-charged pancreatic enzymes. This invention is further directed to a method of treating cancer and inflammation using the zinc-charged pancreatic enzymes.
