Growth rate influences reductive biodegradation of the organophosphorus pesticide demeton by Corynebacterium glutamicum.

abstract：:A Monte Carlo model was developed to characterize the molecular composition of polychlorinated alkane mixtures. The model is based upon a simulation of the free-radical chlorination process by which polychlorinated alkane mixtures are produced industrially from n-alkanes.
