The bactericidal activity of pediocin PA-1 is specifically inhibited by a 15-mer fragment that spans the bacteriocin from the center toward the C terminus

Article Abstract:

A study was conducted to determine a 15-mer peptide fragment from the C-terminal half of the pediocin-like bacteriocin, pediocin PA-1, that inhibits the bactericidal activity of pediocin PA-1. Results suggested that polypeptide chains ,au be divided into two functional domains based on the primary and three-dimensional structures of bacteriocins. Findings also indicated that the interaction of a membrane component with residues of a specificity-determining region supported the permeabilization of the membrane.

Effectiveness of germicidal UV radiation for reducing fungal contamination within air-handling units

Article Abstract:

Germicidal UV lamps installed inside air-handling units in central heating, ventilation, and air-conditioning systems can reduce the amount of mold growing inside the units. This was the conclusion of researchers who installed the lamps in the HVAC system of an office building.

Documentation of the claim that modulation of UV light pulses increases the bactericidal effectiveness of the light

Article Abstract:

Additional information is provided in this correspondence on the bactericidal activity of modulated light pulses froma germicidal lamp. A previous report on the results of a study omitted technical details necessary to support
