Microbial Bioremediation of Hydrocarbons01:26

Microbial Bioremediation of Hydrocarbons

Bioremediation is an environmentally sustainable process that employs living organisms—primarily microorganisms—to degrade or neutralize pollutants from contaminated environments. In oil spills and hydrocarbon pollution, bioremediation involves the use of hydrocarbon-degrading bacteria to transform toxic compounds into less harmful substances. This approach leverages natural microbial metabolic processes and is considered both cost-effective and ecologically favorable compared to physical or...
Bioremediation00:46

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
Biological Treatment of Effluent and Waste Water01:30

Biological Treatment of Effluent and Waste Water

Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
Coagulation01:06

Coagulation

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...
Biofuels01:25

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...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Summary

Mucor rouxii fungal biomass effectively removes oils from water, achieving 77-93% removal. While effective, its oil adsorption capacity is lower than chitosan and walnut shell media.

Area of Science:

  • Environmental Science
  • Biotechnology
  • Materials Science

Background:

  • Wastewater treatment often faces challenges with oil contamination.
  • Biomaterials offer a sustainable approach for removing pollutants like oil from water.

Purpose of the Study:

  • To evaluate the oil removal efficiencies of four biomaterials: Mucor rouxii, Absidia coerulea, chitosan, and walnut shell.
  • To compare the adsorption capacities of these biomaterials for different types of oil.

Main Methods:

  • A batch study was performed using standard mineral oil, vegetable oil, and cutting oil.
  • Initial oil concentration was 200 mg/L, with a contact time of 6 hours.
  • Non-viable fungal biomasses (M. rouxii, A. coerulea) and other biomaterials were tested at pH 5.0.

Main Results:

  • Non-viable Mucor rouxii biomass demonstrated higher oil removal efficiency than Absidia coerulea.
  • M. rouxii achieved oil removal efficiencies ranging from 77% to 93%.
  • Adsorption capacities for M. rouxii were 77.2 mg/g (mineral oil), 92.5 mg/g (vegetable oil), and 84 mg/g (cutting oil).

Conclusions:

  • Mucor rouxii is an effective biomaterial for removing various oils from water.
  • Chitosan and walnut shell media exhibited greater oil adsorption capacities compared to M. rouxii biomass.
