Questions and Answers

What is biodegradation?

  • A chemically catalyzed process by which inorganic substances are broken down into smaller compounds by non-living organisms
  • A biologically catalyzed process by which organic substances are broken down into smaller compounds by living organisms (correct)
  • A process by which organic substances are synthesized by living organisms
  • A process by which inorganic substances are broken down into larger compounds by living organisms

    • What is the difference between composting and biodegradation?

  • Composting is a chemically catalyzed process, while biodegradation is a biologically catalyzed process
  • Biodegradation is a controlled process, while composting is a natural process
  • Composting involves inorganic waste, while biodegradation involves organic waste
  • Composting is a natural breaking down process of organic wastes by microorganisms under controlled conditions, while biodegradation is a natural breaking down process of organic waste by microorganisms (correct)

    • What is the term used when biodegradation is complete?

  • Oxidation
  • Decomposition
  • Fermentation
  • Mineralization (correct)

    Study Notes

    Biodegradation

    • Biodegradation is the process of breaking down organic materials by microorganisms, such as bacteria, fungi, and yeast, into simpler compounds.

    Composting vs Biodegradation

    • Composting is a specific type of biodegradation that involves the aerobic decomposition of organic matter, typically in a controlled environment, to produce a stable humus-like product.
    • Biodegradation is a broader term that encompasses various types of decomposition, including anaerobic decomposition, which occurs in the absence of oxygen.

    Completion of Biodegradation

    • The term used when biodegradation is complete is "mineralization", which refers to the conversion of organic matter into inorganic compounds, such as carbon dioxide, water, and minerals.

    Compostable Products

    • A compostable product is required to break down into carbon dioxide, water, and biomass at a rate consistent with known compostable materials, and leave no toxic residues, in a composting system.

    Applications of Biodegradation

    • The degradative abilities employed in biodegradation are used for various purposes, including waste management, environmental remediation, and the production of biofuels and biochemicals.
