Photosynthetically oxygenated acetonitrile biodegradation by an algal-bacterial microcosm: a pilot-scale study
(2005) In Water Science and Technology 51(12). p.261-265- Abstract
- A 43-L column photobioreactor wash tested for the treatment of acetonitrile Using a symbiotic consortium consisting of a Chlorella sorokiniana strain and a Comamonas strain. Complete biodegradation of 1 g acetonitrile/l was achieved in 79 hours under continuous illumination at 500 mu E/m(2) s and 26 degrees C. When the photobioreactor was operated at 26 degrees C under a 14/10 hours light/dark illumination regime at 500 mu E/m(2) S, complete.mineralization of 1 g acetonitrile/l was achieved in. 111, hours. However, when acetonitrile was supplied at 2 g/l, the biodegradation process was severely inhibited by the increase of pH and NH4+ concentration during cultivation. In addition to saving energy for aeration, the microalgae assimilated... (More)

However, when acetonitrile was supplied at 2 g/l, the biodegradation process was severely inhibited by the increase of pH and NH4+ concentration during cultivation. In addition to saving energy for aeration, the microalgae assimilated 33% of the NH4+ released during acetonitrile biodegradation, which significantly reduces the need for subsequent nitrogen removal.
