D. Rambabu, K. R. Viswakarma, Y. G. Thundu , L. Kanneboina Biodegredation, environment, clean, crop 22-24 Volume 2 (2) March 2026 Biodegradation involves the decomposition of organic materials through the metabolic activities of living organisms, primarily microorganisms. This naturally occurring phenomenon contributes significantly to the recycling of organic matter and the maintenance of ecological balance. During this process, complex chemical compounds are progressively transformed into simpler substances, many of which are less toxic. Intermediate compounds formed during degradation often serve as energy sources for other microorganisms, resulting in a chain of biological reactions that may ultimately lead to complete breakdown. When degradation is partial, it is referred to as primary biodegradation, whereas complete conversion into basic inorganic substances such as carbon dioxide and water is known as ultimate biodegradation or mineralization. This capability makes biodegradation an important natural mechanism for reducing environmental contamination and supporting ecosystem health.
