Abstract:
The present invention provides a screening method of Bacillus phage endolysin genes from an Escherichia coli library including the Bacillus phage endolysin genes using T7 phage. By producing a Bacillus phage endolysin gene library using Escherichia coli as a host, and processing the library with T7 phage, the Bacillus phage endolysin genes can be rapidly and economically separated in a non-toxic condition. efficiency.

Abstract:
PURPOSE: A bacteriophage SFP10 for inducing apoptosis of O157 E.coli and Salmonella and a composition including the same are provided to develop a method for controlling antibiotics resistance. CONSTITUTION: A bacteriophage SFP10(KCTC 11684BP) has host sensitivity to O157 E.coli and samonella. A composition for killing bacteria contains the bacteriophage SFP10(KCTC 11684BP) as an active ingredient. The bacteria include O157 E.coli or salmonella. The salmonella is Salmonella typhimurium or Salmonella enteritidis. A formulation is a liquid phase, semi-solid phase, or powder phase.
Abstract:
PURPOSE: A food and feed composition containing bacteriophage-derived novel endolysin LysBPS 13 are provided to ensure baceriolysis function specific to E.coli and Salmonella. CONSTITUTION: An endolysin LysBPS13 contains an amino acid sequence of sequence number 2. The amino acid of sequence number 2 is encoded by a nucleic acid of sequence number 1. The endolysin LysBPS13 is derived from Bacillus cereus infected bacteriophage BPS13(KCTC 12061). A food additive contains endolysin LysBPS13. A feed additive contains endolysin LysBPS13.
