A rapid quantification method, based on Fourier transform near-infrared (FT-NIR) spectroscopy, was developed and validated to nondestructively quantify the concentrations of volatile fatty acids and ethanol in the effluent of an anaerobic H 2 -producing bioreactor. The first-derivative spectra calculated by a simple numerical difference, combined with the orthogonal signal correction method,...
Anaerobic acidogenesis of Canna indica L. (canna) by rumen cultures was investigated in this study. Fractional factorial design (FFD) was used to explore the roles of the growth factors such as substrate concentration and pH in such a bioconversion, whereas response surface methodology (RSM) was employed for optimizing this acidogenic process. The optimum substrate concentration and pH for the acidogenesis...
