This addendum to “Novel application of bacteriophage for controlling foaming in wastewater
treatment plant- an eco-friendly approach “ includes characteristics of the phages NOC1, NOC2 and
NOC3 not discussed in the previous paper. The phage adsorption and host interaction properties,
their sensitivity to pH and temperature are inferred. NOC2 is seen to be more temperature resistant
while others are not. All the phages show pH sensitivity. There is a variance observed in the
behavior of these phages. Also, applicability of the phage based system to large scale reactors is
studied and discussed here
