生物降解检测:方法选择与完全降解OA

This review systematically examines biodegradation detection methods in relation to the progressive stages of degradation,ranging from residual polymers and disintegrated fragments to intermediate metabolites and fully mineral-ized products,with a focus on accurately quantifying the extent of biodegradation.Existing analytical techniques are com-prehensively compared and evaluated in terms of their accuracy,sensitivity,and practical efficiency in determining degra-dation degrees.The analysis provides critical guidance for selecting appropriate biodegradation assessment strategies tai-lored to specific materials and environmental conditions.Notably,the review advocates for redefining the endpoint of"complete biodegradation"not solely by the presence of mineralized end-products,but by the formation of biologically as-similable intermediates that can be readily utilized by microorganisms.This paradigm shift holds significant potential to shorten testing cycles and paves the way for the development of accelerated,biologically relevant biodegradation detec-tion protocols.
