+ Able to produce lytic zone, - was unable to produce lytic zone. The spot-test-positive strains were selected to perform the EOP test. The EOP values were calculated by the ratio of phage titer on the test bacterium relative to the phage titer on the host bacteria. High production efficiency is EOP ≥ 0.5, moderate production efficiency is 0.5 > EOP ≥ 0.1, low production efficiency is 0.1 > EOP > 0.001, and the inefficiency of phage production is EOP ≤ 0.001. Experiments were undertaken independently in duplicate with the duplicate assay.
