Microbial Degradation Database

OASIS Microbial degradation database was created and is maintained by LMC.



Chemical Identification


Parent chemicals are defined with CAS, SMILES and chemical name(s), while metabolites are described with SMILES and chemical name(s). For each parent chemical there is a catabolic map presenting the biotransformations leading to occurrence of the observed metabolites. When the transformation is activated by enzyme or class of enzymes a corresponding indication is added to the map. Along with biotransformations each map is accompanied with additional supporting information - test species details, experimental conditions, sampling and processing methods, dosing information, etc.





The database contains 551 documented metabolic maps for 514 unique parent chemicals with observed catabolic pathways of various compounds, mostly pesticides, fungicides and herbicides in aerobic conditions [1 - 11]. Every map is accompanied with rich collection of chemical, transformation and experimental data. Test variations are represented as different treatment groups (studies) that show the influence of various experimental conditions on the occurrence of each metabolite. This results in 668 studies, which can be categorized by various criteria, for example by species. Below is presented the distribution by test organism:


  • Bacteria - 68%,
  • Microorganisms (not defined) - 28%,
  • Fungi - 4%.
