Insights

Fungi can biologically remove carbon deposits from aircraft engine parts, offering a faster, cleaner alternative to chemical methods. This new biotechnological approach utilizes specific fungal strains for effective decarbonization.

Area of Science:

  • Mycology
  • Biotechnology
  • Materials Science

Context:

  • Carbon deposits, or fouling, accumulate on aircraft engine parts during operation.
  • Current chemical methods for removing fouling are laborious, slow, and environmentally unfriendly.
  • There is a need for more efficient and sustainable methods for aircraft part maintenance.

Purpose:

  • To isolate and identify fungal species capable of degrading carbon deposits.
  • To develop a biotechnological method for removing fouling from aircraft engine parts (PAE).
  • To evaluate the effectiveness and environmental benefits of the fungal-based method compared to chemical treatments.

Summary:

  • Several fungal species, including Penicillium and Aspergillus strains, were isolated.
  • These fungi demonstrated active degradation of carbon deposits found on aircraft engine parts.
  • A novel, less laborious, faster, and ecologically cleaner biotechnological method for PAE decarbonization was developed.
  • Scanning electron microscopy (SEM) was proposed as a tool to assess the degree of decarbonization.

Impact:

  • This research presents a sustainable and eco-friendly alternative for aircraft engine maintenance.
  • The developed biotechnological method offers significant advantages in terms of speed and reduced environmental impact.
  • The findings could lead to improved operational efficiency and reduced costs in the aviation industry.

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

Chemical Agents for Microbial Control

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...

Physical Methods for Controlling Microbial Growth: Radiation and Filtration

Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

Microbial Bioremediation of Pesticides

Pesticides often feature structurally complex chemical architectures, incorporating halogen groups and multiple aromatic rings. These characteristics confer high chemical stability, rendering many pesticides resistant to natural degradation processes. This resistance poses significant environmental concerns, as persistent pesticide residues can accumulate in ecosystems and affect non-target organisms.Despite the inherent stability of many pesticides, certain microorganisms possess the metabolic...

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...
