title: Biotransformation of limonene by Pseudomonas putida.
abstract: From a study of three fungal and 15 bacterial strains, it was observed that Pseudomonas putida MTCC 1072 oxidized limonene with the highest efficiency of. Fermentation of limonene by P. putida MTCC 1072 was conducted for 120 h at 30 degrees C at a fixed pH of 5.0. Major bioconversion products were isolated and characterized by Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy, and by elemental analysis. The bioconversion products were identified as perillyl alcohol and p-menth-1-ene-6,8-diol, and under optimum conditions the yields were 36% and 44%, respectively (a rate kinetic model indicated corresponding limiting yields of 44% and 56%). No further degradation of the products was observed using this bacteria.
