Abstract

A P. maximum homogeneous sample with different average gas volumes accumulated through time was used as a reference to evaluate the influence of an inner reference sample and a feces mixture upon gas in vitro production generating capacity. Effectiveness assessment of this kind of correction was performed by studying A. bilimekii, H. brasiletto, and A. pennatula samples. This correction consisted in multiplying the sample hourly accumulated volume by the average volume ratio between the standard and the studied samples. Such a correction improved generating capacity in every case; however, variation coefficients from highly different feces mixtures were over 100 % indicating effectiveness limitations. Concerning the assessment of feces mixture influence, S.officinarum samples, two macroscopically different inocula, and a mixture of both were used. Variability was higher when using non-mixed feces compared to mixed ones, but variation coefficient levels for inocula remained within a 5 % range in some cases. Further work is needed to find out suitable indicators to control inoculum power.
