What process involves microorganisms breaking down organic matter in the presence of oxygen?

Aerobic digestion is a biological process in which microorganisms, such as bacteria, decompose organic matter in the presence of oxygen. This process is commonly used in wastewater treatment and composting because it helps break down complex organic materials into simpler substances, reducing environmental impact and producing byproducts such as carbon dioxide and water. The presence of oxygen is crucial in this process as aerobic microorganisms rely on it to efficiently metabolize and convert organic matter, leading to a more effective breakdown and stabilization of materials. This is why aerobic digestion is a fundamental method within various biological treatment applications, promoting effective waste management and environmental protection.
