Physical Methods for Controlling Microbial Growth: Radiation and Filtration01:26

Physical Methods for Controlling Microbial Growth: Radiation and Filtration

937
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.

Filtration and Urine Formation

53.1K
The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.

Area of Science:

  • Environmental Science
  • Water Treatment Technology
  • Molecular Biology

Background:

  • Fecal contamination of drinking water poses a global health risk due to difficult virus detection and treatment.
  • Existing water treatment methods for viruses often require high energy or chemical inputs.
  • Sand filtration is a widely used, practical water treatment technology worldwide.

Purpose of the Study:

  • To investigate the molecular mechanism behind unprecedented high virus removal in functionalized sand filters.
  • To evaluate the efficacy of Moringa oleifera (MO) seed-derived functionalized sand (f-sand) for virus removal.
  • To explore the regeneration of f-sand filters for practical application.

Main Methods:

  • Functionalization of sand filters using a water extract of Moringa oleifera (MO) seeds.
  • Virus removal efficiency testing using MS2 bacteriophage as a surrogate for human enteric viruses.
  • Proteomic analysis and molecular docking simulations to identify the virus-binding mechanism.
  • Development of a simplified f-sand preparation and regeneration process using saline water.

Main Results:

  • Functionalized sand (f-sand) filters achieved approximately 7 log10 virus removal.
  • The high virus removal activity was attributed to the presence of a chitin-binding protein (MoCBP) from MO seeds.
  • Molecular docking simulations confirmed specific binding interactions between MoCBP and MS2 bacteriophage capsid proteins.
  • A simplified method for f-sand preparation and regeneration with saline water was demonstrated.

Conclusions:

  • Specific molecular interactions mediated by MoCBP are responsible for the enhanced virus removal by f-sand filters.
  • Functionalized sand (f-sand) filters offer a highly effective, energy-efficient, and practical solution for removing viruses from contaminated water.
  • This technology has significant potential for application in both developing and developed countries for safe drinking and irrigation water.
