A unified model for the growth of Desulfovibrio vulgaris under different environmental conditions is pre- sented. The model assumes the existence of two electron transport mechanisms functioning simultaneously. One mechanism results in the evolution and consumption of hydrogen, as in the hydrogen-cy

✦ Synopsis
We prove the instability of optimal balanced paths in endogenous growth models, as long as transversality conditions are satisÿed. Moreover, we prove the complete instability of models with one state variable, whereas, in models with two and three state variables, we o er necessary and su cient conditions for the saddle point property to occur. Our results generalize some classical stability results of steady states in neoclassical growth models, to balanced paths in the new endogenous growth models.
