Microbial Fuel Cells01:23

Microbial Fuel Cells

Microbial fuel cells (MFCs) are bioelectrochemical devices that generate electricity by exploiting the metabolic processes of electrogenic bacteria. These systems provide a renewable energy source and serve as an innovative method for treating organic waste, such as wastewater.A typical MFC consists of two chambers: an anoxic (oxygen-free) compartment that houses the bacteria and an oxic (oxygen-rich) compartment that contains oxygen as the terminal electron acceptor. Many MFCs use proton...

Biofuels

The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...
Biofilms01:29

Biofilms

Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Infectious Diseases

Background:

  • Chronic biofilm infections are a major health concern, particularly in diabetic wounds.
  • Existing treatments often struggle with biofilm resistance and effective wound management.

Purpose of the Study:

  • To develop a self-powered dressing for electrotherapy of infected diabetic wounds.
  • To create a system that utilizes biofilm components for autonomous energy generation and antibacterial action.

Main Methods:

  • Constructed a biofilm-activated enzymatic biofuel cell-based dressing (EBFC) using lactate oxidase and bilirubin oxidase bioanodes/biocathodes.
  • Incorporated *Lactobacillus rhamnosus* (LG)-loaded sodium alginate hydrogel as an electrolyte.
  • Investigated EBFC's ability to consume biofilm extracellular polymeric substances and produce lactate for fuel.

Main Results:

  • The EBFC demonstrated consumption of biofilm EPS, disrupting biofilms and generating electricity (approx. 240 mV for >30 h).
  • LG-secreted bactericidal metabolites provided direct antibacterial effects against biofilm bacteria.
  • Synergistic action of electrotherapy and antibacterial properties accelerated wound healing *in vivo*.

Conclusions:

  • The EBFC offers a promising self-powered electrotherapy strategy for biofilm-infected diabetic wounds.
  • Harnessing biofilm components as an energy source enables autonomous operation and synergistic antibacterial effects.
  • This approach facilitates sterilization, suppresses inflammation, and promotes wound healing through enhanced collagen deposition and angiogenesis.
