Abstract

The Escherichia coli (E. coli) has been widely employed in biotechnology industry and academia. However, the bioproduct manufacturing driven by E. coli is prone to the phage contamination. Good laboratory/factory hygiene may decrease but not avoid completely the chances of the phage contamination. The present study aims to resolve this problem by engineering laboratory/factory-specific phage-resistant E. coli strains. By adding a laboratory or factory derived phage into the atmospheric and room temperature plasma mutagenized E. coli, a phage-resistant strain could be generated. Interestingly, the resistant strain exhibited cross-resistance to unencountered phages. When operating the resistant strain in a polluted environment, the phage contamination was largely prevented. There was no significant difference in heterogeneous protein production between the parental strain and the phage-resistant strain. Importantly, it requires only one day to generate the phage-resistant strain. This practical method for engineering laboratory/factory-specific phage-resistant strains may have great potential in resuming E. coli operation in laboratories and factories during phage contamination outbreaks.

Data availability

The codon-optimized Haemophilus ducreyi nicotinamide phosphoribosyltransferase with a C-terminal six histidine tag was deposited at GenBank (Accession No: MW759281). The sequencing files in fastq format obtained from whole-genome sequencing of the strain Hd1 were submitted to the NCBI under SRA accession number PRJNA783137. The GenBank accession numbers for the E. coli BL21 reference genome were CP060121.1, CP053602.1, and AM946981.2.
