Pseudomonas putida CSV86 metabolizes 1- and 2-methylnaphthalene through distinct catabolic and detoxification pathways. In spite of the similarity in the steps involved in the methylnaphthalene detoxification and the toluene side-chain hydroxylation pathways, the strain failed to utilize toluene or xylenes.

The porous coordination polymer (PCP) [Cu(2)(BDC)(2)(dabco)] is capable of selectively adsorbing up to 25 wt % of either 1-methylnaphthalene or 2-methylnaphthalene. Uptakes of unsubstituted naphthalene and 1,4-dimethylnaphthalene are significantly lower (7-13 wt %), suggesting that monomethyl substituted polyaromatics can be
