Question

Principles of biodegradation of toxic waste

Answer 1

Biodegradation is the disintegration of materials by bacteria, fungi, or other biological means.

The term is often used in relation to: biomedicine, waste management, ecology, and the bioremediation of the natural environment. It is now commonly associated with environmentally-friendly products, capable of decomposing back into natural elements.

Although often conflated, biodegradable is distinct in meaning from: compostable. While biodegradable simply means can be consumed by microorganisms, compostablemakes the further specific demand that the object break down under compostingconditions.

Organic material can be degraded aerobically(with oxygen) or anaerobically (without oxygen). Decomposition of biodegradable substances may include both biological and abiotic steps.

Biodegradable matter is generally organic material that provides a nutrient for microorganisms. These are so numerous and diverse that a huge range of compounds can be biodegraded, including hydrocarbons (oils), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and pharmaceutical substances. Microorganismssecrete biosurfactant, an extracellular surfactant, to enhance this process.

Answer 2

Concept Introduction:

The degradation of organic material by microorganisms like bacteria and fungi is known as biodegradation. This distinguishes it from composting because it is typically thought to be a gradual process. In the human-driven process of composting, biodegradation takes place under a certain set of conditions.

Explanation:

We have been given a question about biodegradation.

We have to find the principles of biodegradation of toxic waste.

The breakdown of substances by bacteria, fungi, or even other biological materials is known as biodegradation. The phrase is frequently used in connection with biomedicine, waste disposal, ecology, and the biotransformation of the environment. It is now frequently connected to items that are friendly to the environment and can break down into their natural components.

Final Answer:

The final answer is the breakdown of substances by bacteria, fungi, or even other biological materials is known as biodegradation.
