Microbial degradation of acetonitrile using a suspended-carrier biofilm process
(2002) In Biotechnology Letters 24(4). p.287-291- Abstract
- A microbial process for the destruction of acetonitrile has been developed. Suitable microorganisms were enriched from activated sludge by cultivation with a high selection pressure when acetonitrile was the sole source of carbon and nitrogen. The process is based on cultivating the microorganisms as a biofilm on plastic carriers. These are utilised in a stirred-tank reactor with continuous feeding of 40-150 mM acetonitrile and an outlet for spent medium. The observed efficiency in the conversion process was from 53-100%, depending on the organic load. To improve the capacity and reliability of the process, a two-step process was developed with two stirred-tank reactors coupled in series. With such an arrangement, conversion efficiencies... (More)
