Abstract
The emergence of antibiotic-resistant strains, the decreased effectiveness of conventional therapies, and the side effects have led researchers to seek a safer, more cost-effective, patient-friendly, and effective method that does not develop antibiotic resistance. With progress in synthetic biology and genetic engineering, genetically engineered microorganisms effective in treatment, prophylaxis, drug delivery, and diagnosis have been developed. The present study reviews the types of genetically engineered bacteria and phages, their impacts on diseases, cancer, and metabolic and inflammatory disorders, the biosynthesis of these modified strains, the route of administration, and their effects on the environment. We conclude that genetically engineered microorganisms can be considered promising candidates for adjunctive treatment of diseases and cancers.

Abstract
Advances in genetic engineering, synthetic biology, and DNA sequencing have transformed the re-emergent therapeutic bacteriophage field. The increasing rate of multidrug resistant (MDR) infections and the speed at which new bacteriophages can be isolated, sequenced, characterized, and engineered has reinvigorated phage therapy and unlocked new applications of phages for modulating bacteria. The methods used to genetically engineer bacteriophages are undergoing significant development, but identification of heterologous gene payloads with desirable activity and determination of their impact on bacteria or human cells in translationally relevant applications remain underexplored areas. Here, we discuss and categorize recombinant gene payloads for their potential outcome on phage-bacteria interactions when genetically engineered into phage genomes for expression in their bacterial hosts.

Abstract
AIMS Isolation and characterization of Enterococcus phages and application of phage cocktail to control E. faecalis in milk. METHODS AND RESULTS For phage isolations, double layer agar method was used. Host range of the phages were determined by the spot test. Twelve phages with varying host ranges were isolated. Phages PEF1, PEF7b, and PEF9 with different host ranges and lytic activities were selected for phage cocktails. Compared to two-phages cocktails tested, the cocktail containing all the three phages displayed stronger antibacterial and biofilm removal activities. The cocktail treatment reduced viable E. faecalis in biofilm by 6 log within 6 h at both 30°C and 4°C. In milk, the cocktail gradually reduced the viable count of E. faecalis and the count reached below the lower limit of detection at 48 h at 4°C. CONCLUSION The strong bactericidal and biofilm removal activities of the phage cocktail suggest the potential of this cocktail as a natural biocontrol agent for combating E. faecalis in milk.

Abstract
Bacteriocins are a large family of peptides synthesized ribosomally by a variety of bacterial species. The genome of one of the thermophilic Gram-positive bacteria, Aeribacillus pallidus PI8, was found to possess an operon comprising five genes possibly involved in the production of a putative bacteriocin that was named pcnABCDE for the production of "pallidocyclicin." This study investigated the function of the pcn operon experimentally. The heterologous expression of the entire pcn operon from the plasmid was toxic to Escherichia coli but not to Bacillus subtilis. However, when the entire pcn operon was expressed constitutively, even the growth of B. subtilis was impaired, and at least pcnA was implied to serve as the precursor of pallidocyclicin. In addition, a strain of B. subtilis expressing the entire pcn operon from the plasmid showed toxicity to another thermophilic species, Geobacillus kaustophilus, at elevated temperatures, whereas another strain lacking pcnE alone from the pcn operon lost the toxicity, suggesting that pcnE might be involved in the biosynthesis of pallidocyclicin when it is produced in B. subtilis.

Abstract
Seafood products are one of the most perishable foods, and their shelf life is limited by enzymatic and microbial spoilage. Developing methods to extend the shelf life of fresh fish could reduce food waste in the fishery industry, retail stores, and private households. In recent decades, the application of lactic acid bacteria (LAB) as bioprotective cultures has become a promising tool. In this study, we evaluated the use of four starter cultures, previously selected for their properties as bioprotective agents, for sea bass and sea bream burgers biopreservation. Starter cultures impacted the microbial populations, biochemical parameters (pH, TVB-N), and sensory properties of fish burgers, during 10 days of storage at 4 °C and then 20 days at 8 °C in modified atmosphere packaging (MAP). Also, storage time influenced the microbial and physicochemical characteristics of all the tested samples, except for TVB-N values, which were significantly higher in the uninoculated burgers. The volatilome changed in the different treatments, and in particular, the samples supplemented with starter presented a profile that described their rapid growth and colonization, with the production of typical molecules derived from their metabolism. The addition of bioprotective cultures avoided bloating spoilage and improved the sensory parameters of the burgers. The shelf life of the fish burgers supplemented with starter cultures could be extended up to 12 days.

Abstract
The global spread of multi- and pan-resistant bacteria has triggered research to identify novel strategies to fight these pathogens, such as antimicrobial peptides and, more recently, bacteriophages. In a proof-of-concept study, we have genetically modified lytic T7Select phages targeting Escherichia coli Rosetta by integrating DNA sequences derived from the proline-rich antimicrobial peptide, apidaecin. This allowed testing of our hypothesis that apidaecins and bacteriophages can synergistically act on phage-sensitive and phage-resistant E. coli cells and overcome the excessive cost of peptide drugs by using infected cells to express apidaecins before cell lysis. Indeed, the addition of the highly active synthetic apidaecin analogs, Api802 and Api806, to T7Select phage-infected E. coli Rosetta cultures prevented or delayed the growth of potentially phage-resistant E. coli Rosetta strains. However, high concentrations of Api802 also reduced the T7Select phage fitness. Additionally, plasmids encoding Api802, Api806, and Api810 sequences transformed into E. coli Rosetta allowed the production of satisfactory peptide quantities. When these sequences were integrated into the T7Select phage genome carrying an N-terminal green fluorescent protein (GFP-) tag to monitor the expression in infected E. coli Rosetta cells, the GFP–apidaecin analogs were produced in reasonable quantities. However, when Api802, Api806 and Api810 sequences were integrated into the T7Select phage genome, expression was below detection limits and an effect on the growth of potentially phage-resistant E. coli Rosetta strains was not observed for Api802 and Api806. In conclusion, we were able to show that apidaecins can be integrated into the T7Select phage genome to induce their expression in host cells, but further research is required to optimize the engineered T7Select phages for higher expression levels of apidaecins to achieve the expected synergistic effects that were visible when the T7Select phages and synthetic Api802 and Api806 were added to E. coli Rosetta cultures.

Abstract
Bacteriophages, abbreviated as "phages", have been developed as emerging nanoprobes for the detection of a wide variety of biological species, such as biomarker molecules and pathogens. Nanosized phages can display a certain length of exogenous peptides of arbitrary sequence or single-chain variable fragments (scFv) of antibodies that specifically bind to the targets of interest, such as animal cells, bacteria, viruses, and protein molecules. Metal nanoparticles generally have unique plasmon resonance effects. Metal nanoparticles such as gold, silver, and magnetism are widely used in the field of visual detection. A phage can be assembled with metal nanoparticles to form an organic-inorganic hybrid probe due to its nanometer-scale size and excellent modifiability. Due to the unique plasmon resonance effect of this composite probe, this technology can be used to visually detect objects of interest under a dark-field microscope. In summary, this review summarizes the recent advances in the development of phage-based probes for ultra-sensitive detection of various bio-species, outlining the advantages and limitations of detection technology of phage-based assays, and highlighting the commonly used editing technologies of phage genomes such as homologous recombination and clustered regularly interspaced palindromic repeats/CRISPR-associated proteins system (CRISPR-Cas). Finally, we discuss the possible scenarios for clinical application of phage-probe-based detection methods.

Abstract
The alarming rise in antimicrobial resistance coupled with a lack of innovation in antibiotics has renewed interest in the development of alternative therapies to combat bacterial infections. Despite phage therapy demonstrating success in various individual cases, a comprehensive and unequivocal demonstration of the therapeutic potential of phages remains to be shown. The co-evolution of phages and their bacterial hosts resulted in several inherent limitations for the use of natural phages as therapeutics such as restricted host range, moderate antibacterial efficacy, and frequent emergence of phage-resistance. However, these constraints can be overcome by leveraging recent advances in synthetic biology and genetic engineering to provide phages with additional therapeutic capabilities, improved safety profiles, and adaptable host ranges. Here, we examine different ways phages can be engineered to deliver heterologous therapeutic payloads to enhance their antibacterial efficacy and discuss their versatile applicability to combat bacterial pathogens.
