Notes:
The kinetics of the prehydrolysis of rice hulls where investigated with different concentrations of H2SO4 and temperatures by modified ARRHENIUS-equation in relation to the degradation of pentosans and the formation of reducing sugars. The determination of the activation energy, the frequency-factor and the orden of reaction in relation to the concentration of the acid results for the formation of the reducing sugars in 60.3 kJ/mol, 5.28 ×. 107 and 1.76, for the degradation of the pentosans in 59- and 69.9 kJ/mol, 3.08 × 107 and 6.03 times; 107 as well as 0.76 and 0.85The discontinuous growth of the yeast Candida tropicalis QML 7601, isolated from a biotop in Cuba, on the products of the prehydrolysis of the rice hulls with H2SO4 (0.1- and 0.2 N) and different mixtures of H2SO4 and HNO3 yield values of μmax = 0.3 - 0.6 h-1 in relation to the conditiones.
