E. coli plasmid DNA production
General methods and strains of bacteria are described that dramatically simplify and streamline plasmid DNA production. In one preferred embodiment, endolysin mediated plasmid extraction combined with flocculation mediated removal of cell debris and host nucleic acids achieves increased yield and purity with simplified downstream purification and reduced waste streams, thus reducing production costs.

Linear vectors, host cells and cloning methods
Linear vectors derived from bacteriophage of E. coli and host cells suitable for cloning are provided. The linear vectors include a left arm comprising a left telomere and a first selectable marker, a right arm comprising a right telomere and a second selectable marker and a cloning region located between the left arm and the right arm. Optional further components of the vector include transcriptional termination sequences, multiple cloning sites and reporter stuffer regions.

BACTERIAL DELIVERY VEHICLE, PROCESS OF PRODUCTION AND USES THEREOF
The present invention relates to the delivery of a payload by bacterial delivery vehicle, i.e. the encapsulation and the delivery of a single plasmid by different bacterial virus particles. More specifically, the present invention concerns a pharmaceutical composition comprising a payload packaged in at least two different bacterial delivery vehicles and a method of production thereof.
Evolution of proteases
Some aspects of this disclosure provide methods for phage-assisted continuous evolution (PACE) of proteases. Some aspects of this invention provide methods for evaluating and selecting protease inhibitors based on the likelihood of the emergence of resistant proteases as determined by the protease PACE methods provided herein. Some aspects of this disclosure provide strategies, methods, and reagents for protease PACE, including fusion proteins for translating a desired protease activity into a selective advantage for phage particles encoding a protease exhibiting such an activity and improved mutagenesis-promoting expression constructs. Evolved proteases that recognize target cleavage sites which differ from their canonical cleavage site are also provided herein.
