Polymers which prevent phage infection of bacteria
Bacteriophage (phage) are present wherever their bacteria hosts are. Phage have huge biotechnological potential, but lytic phages can also cause complete loss of bacterial cultures. For example in the food industry, or in ever research laboratory where rigorous sterile handing is the primary containment strategy. For industrial biotechnology using microorganisms to enable sustainable of chemicals, materials and drugs, phage infection must be addressed. In our latest (patent pending) work, in collaboration with the SagonaLab at Warwick, and Cytiva, we discovered that a simple polymer can prevent phage infection of bacteria when applied to the growth media. This process is simple, requires no change to working practises and prevents phage infections. We are still investigating the mechanistic aspects, but this is virustatic (inhibitory) rather than virucidal.
