  • Title: Co-metabolic degradation of dimethoate by Raoultella sp. X1.
    Author: Liang Y, Zeng F, Qiu G, Lu X, Liu X, Gao H.
    Journal: Biodegradation; 2009 Jun; 20(3):363-73. PubMed ID: 18989739.
    Abstract:
    A bacterium Raoultella sp. X1, based on its 16S rRNA gene sequence, was isolated. Characteristics regarding the bacterial morphology, physiology, and genetics were investigated with an electron microscopy and conventional microbiological techniques. Although the isolate grew and degraded dimethoate poorly when the chemical was used as a sole carbon and energy source, it was able to remove up to 75% of dimethoate via co-metabolism. With a response surface methodology, we optimized carbon, nitrogen and phosphorus concentrations of the media for dimethoate degradation. Raoultella sp. X1 has a potential to be a useful organism for dimethoate degradation and a model strain for studying this biological process at the molecular level.
