Application ofin silico genomic modeling in

bioremediation processes

Clean up nature from pollutants

Conventional methods- expensive;

- non-specific;

- release of intermediate toxic compounds.

Bioremediation

- ecologically focused process;

- an alternative to physical-chemical processes;

- detoxification and degradation of toxic pollutants either by intracellular accumulation or by enzymatic transformation.

Mycoremdiation

In silico toxicity of compounds

✓More than 70 million compounds have been identified by May 2013;

✓ Quantitative structure-activity relationship model;

✓OSIRIS;

✓SuperToxic database, contains information about multiple toxic compounds (about 60,000).
