WebIsolation of Potential Bacterial Enteric Host Strains from Activated Sewage Sludge Two containers (2 liters) of sewage sludge were obtained from the waste water treatment facility located in Nashua, NH. Bacteria were isolated from the sewage sludge by plating 100 ml of sludge onto either TS or TSBW agar. Web8 mrt. 2024 · Three of the bacteriophage isolates, phage/CIRG/1, phage/CIRG/4 and phage/CIRG/5, exhibited lytic activity against over 80% of the staphylococcal isolates. All isolates were stable up to 3 months at 37°C, and for 16 months at 4°C but the stability of their respective endolysins only lasted for 12–23 days at 37°C and 6 months at 4°C.
Webisolation as chloroform tends to inactivate both filamentous and lipid containing bacteriophages [12]. Some researchers are able to isolate phages without doing enrichment cultures by plating environmental samples directly with an isolation host and looking for spot clearing or plaque formation [13,14].
