摘要

Sphingobium yanoikuyae is a metabolically versatile, Gram-negative bacterium within the family Sphingobiaceae, recognized for its exceptional capacity to degrade a broad spectrum of xenobiotic compounds. Its ecological adaptability and enzymatic diversity enable the transformation of structurally complex pollutants into less toxic intermediates across diverse environmental settings. Although members of the genus Sphingobium have been widely studied, a focused and integrative synthesis specifically addressing the metabolic, genomic, and biotechnological attributes of S. yanoikuyae remains limited. This review presents a critical and up-to-date analysis of the taxonomy, genomic architecture, and xenobiotic degradation mechanisms of S. yanoikuyae, with particular emphasis on its functional role in microbial biotechnology. The organism exhibits broad substrate specificity toward hydrocarbons, pesticides, pharmaceuticals, and related compounds, mediated by coordinated enzymatic systems, including ring-hydroxylating dioxygenases, monooxygenases, and cytochrome P450-dependent pathways. Genomic analyses further reveal the presence of multiple catabolic operons, mobile genetic elements, and plasmid-associated gene clusters that collectively underpin its metabolic versatility, regulatory complexity, and adaptive potential. Beyond summarizing current knowledge, this review delineates key mechanistic features of degradation pathways, compares substrate-specific transformation efficiencies, and critically evaluates existing limitations, including incomplete pathway resolution, constraints in genetic manipulation, and variability in environmental performance. Furthermore, it highlights emerging opportunities in systems biology, enzyme engineering, and integrative omics approaches to enhance degradation efficiency and expand application scope. By consolidating current insights and identifying strategic research gaps, this work provides a coherent framework for advancing S. yanoikuyae as a robust platform for targeted applications in environmental remediation and sustainable biotechnology.
