Article Abstract:
Induction time for long-term-starved (60-80 days) cells was primarily affected by quinoline concentration. Long-term starvation resulted in more efficient conversion of quinoline into degradation products at concentrations of 39 and 155 micromoles. Higher concentrations appeared to inhibit induction and reduce efficiency in long-term starved cells. The steady state degradation of quinoline by the long-term-starved cells was similar or better than the short-term-starved cells. Induction times in short-term-starved cells did not increase with increasing quinoline concentration.

Article Abstract:
Washed-cell suspensions of Arthrobacter sp. strain F101 were analyzed to determine the enzymatic activities, metabolites and pathways that mediate fluorene metabolism. Analysis of Arthrobacter strain F101 with fluorene accumulated 9-fluorenone and formyl indanone indicate the occurrence of initial dioxygenation in the C-1, C-2 or at C-3 and C-4 positions. Furthermore, metabolic pathways are characterized by the combined metabolism of aromatic compounds and linear fatty acids such as beta oxidation.

Article Abstract:
The metabolism of 2-amino-3-methylimidazol[4,5-f]quinoline (IQ) by human intestinal microbiota is investigated, using (super 1)H nuclear magnetic resonance spectroscopy-based studies. The (super 1)H nuclear magnetic resonance spectroscopy of crude biological samples allows measurement of a wide range of moelcules simultaneously and without a priori hypotheses concerning their chemical structure.
