Summary
Bacteriophages precisely engineer microbiomes by targeting specific bacteria. This method selectively reduces bacterial populations without harming non-target species, offering a novel approach for microbiome research.
Area of Science:
- Microbiology
- Synthetic Biology
- Genetics
Background:
- Microbiome engineering is crucial for understanding microbial functions.
- Selective bacterial knockdown methods are limited.
- Host-specific bacteriophages offer potential for precise microbiome manipulation.
Purpose of the Study:
- To validate the use of virulent bacteriophages for precise microbiome engineering.
- To demonstrate selective reduction of target bacteria in a mixed microbial community.
- To develop a method for synthesizing virulent phages for microbiome engineering.
Main Methods:
- Utilized a four-species artificial microbiome (Escherichia coli, Pseudomonas putida, Bacillus subtilis, Lactiplantibacillus plantarum).
- Introduced specific bacteriophages targeting each host strain.
- Employed in vivo DNA assembly and phage-rebooting techniques to synthesize a virulent phage derivative.
Main Results:
- Bacteriophages specifically reduced target bacterial populations by over 10^2 orders.
- Non-target bacterial growth remained unaffected, confirming selective targeting.
- Successfully engineered an E. coli-targeted microbiome using a synthesized virulent phage.
Conclusions:
- Bacteriophages are effective tools for precise microbiome engineering.
- Virulent phages can be synthesized from prophage DNA, eliminating the need for environmental isolation.
- This approach offers a novel strategy for microbiome research and manipulation.

Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...
