Application
2,2,4,4,6,8,8-Heptamethylnonane was used to study the effects of loading and aging pyrene in soils. It was also used to study its long term effect on the cell surface hydrophobicity (CSH) of a hexane-degrading Pseudomonas aeruginosa strain and a toluene-degrading Pseudomonas putida strain.

Mixed bacterial cultures aerobically transformed decalin (decahydronaphthalene) dissolved in an immiscible carrier phase (heptamethylnonane; HMN) in liquid medium. Conversion was enhanced in the presence of decane, a readily degraded n-alkane, and/or HMN. Four Rhodococcus spp. isolates purified from one of
