Gene Regulation in Microbial Communities: Quorum Sensing

569
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Methods for Controlling Microbial Growth

1.6K
Microbial growth control refers to various methods employed to inhibit, reduce, or eliminate microorganisms to ensure safety and hygiene across different settings. These methods are categorized based on the target environment and the level of microbial control required.Biocides are versatile agents designed to control microorganisms by either inhibiting their growth or outright killing them. These agents work through various physical, chemical, mechanical, or biological mechanisms. The...

Chemical Agents for Microbial Control

862
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Biological Methods for Microbial Control

878
Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

Physical Methods for Controlling Microbial Growth: Temperature

1.1K
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

Area of Science:

  • Microbial Ecology
  • Systems Biology
  • Synthetic Biology

Background:

  • Microbial communities are essential for ecosystem health and host well-being.
  • Current methods for manipulating microbial communities lack systematic control frameworks.
  • Efficient control is needed to restore ecosystems and maintain healthy microbiota.

Purpose of the Study:

  • To develop an efficient and systematic control framework for complex microbial communities.
  • To introduce the concept of structural accessibility for microbial community manipulation.
  • To identify minimum sets of driver species for community control.

Main Methods:

  • Developed a control framework based on structural accessibility.
  • Utilized ecological network analysis to identify driver species.
  • Validated the framework numerically on large-scale communities.
  • Applied the framework to control gut microbiota in mice and sponge microbial communities.

Main Results:

  • The proposed framework enables systematic control over microbial communities.
  • Identified minimum sets of driver species for targeted community manipulation.
  • Demonstrated successful application in a mouse model of Clostridium difficile infection.
  • Showcased efficacy in controlling the core microbiota of the sea sponge Ircinia oros.

Conclusions:
