Application


  • Aerobic biotransformation of decalin (decahydronaphthalene) by Rhodococcus spp.: This study examines the aerobic biodegradation capabilities of Rhodococcus strains with decalin, highlighting potential applications in bioremediation and industrial bioprocesses (Gray et al., 2008).

  • Discovery and identification of a series of alkyl decalin isomers in petroleum geological samples.: This research utilizes advanced chromatographic techniques to identify and characterize alkyl decalin isomers in petroleum samples, offering insights into petroleum geochemistry and reservoir characterization (Liu et al., 2015).

  • Ultrasound-induced cracking and pyrolysis of some aromatic and naphthenic hydrocarbons.: Explores the effects of ultrasound on the cracking and pyrolysis of hydrocarbons including decahydronaphthalene, offering potential enhancements in chemical processing and analytical methodologies (Cataldo, 2000).
