Abstract:
Heavy and irresponsible use of antibiotics in the last century has put selection pressure on the microbes to evolve even faster and develop more resilient strains. In the confrontation with such sometimes called "superbugs", the search for new sources of biochemical antibiotics seems to have reached the limit. In the last two decades, bioactive antimicrobial peptides (AMPs), which are polypeptide chains with less than 100 amino acids, have attracted the attention of many in the control of microbial pathogens, more than the other types of antibiotics. AMPs are groups of components involved in the immune response of many living organisms, and have come to light as new frontiers in fighting with microbes. AMPs are generally produced in minute amounts within organisms; therefore, to address the market, they have to be either produced on a large scale through recombinant DNA technology or to be synthesized via chemical methods. Here, heterologous expression of AMPs within bacterial, fungal, yeast, plants, and insect cells, and points that need to be considered towards their industrialization will be reviewed.
Insights
Antimicrobial peptides (AMPs) offer a promising alternative to traditional antibiotics against drug-resistant bacteria. This review explores their production and industrialization for effective microbial control.
Area of Science:
- Microbiology
- Biochemistry
- Molecular Biology
Background:
- Antibiotic resistance is a growing global threat due to the overuse of conventional antibiotics.
- The emergence of multidrug-resistant bacteria, or "superbugs," necessitates novel therapeutic strategies.
- Bioactive antimicrobial peptides (AMPs) have emerged as a significant class of molecules for combating microbial pathogens.
Purpose of the Study:
- To review the potential of antimicrobial peptides (AMPs) as alternatives to conventional antibiotics.
- To discuss the challenges and considerations for the industrial-scale production of AMPs.
- To explore methods for large-scale AMP production, including recombinant DNA technology and chemical synthesis.
Main Methods:
- Review of current literature on antimicrobial peptides (AMPs).
- Analysis of heterologous expression systems for AMP production (bacterial, fungal, yeast, plant, insect cells).
- Evaluation of industrialization requirements for AMPs.
Main Results:
- Antimicrobial peptides (AMPs) show significant promise in controlling microbial pathogens.
- Large-scale production of AMPs requires efficient methods like recombinant DNA technology or chemical synthesis.
