Deskripsi

The experiment was carried out to examine the organic acids production of rice straw fermentedwith some types of microorganisms at different temperatures. The experiment was designed as SplitPlot-Completely Randomized Design. The main plot was temperatures treatments (25, 35, 45°C) and thesub plot were microorganisms (Control, Control+Mollases, Lactobacillus fermentum, Bacillus subtilis,Bacillus coagulant, Saccharomyces cerevisiae, Aspergillus niger). The highest lactic acid productionswas in B. coagulans treatment at 35°C (53.79 g/kg DM). The highest acetic acid productions was in L.fermentum at 35°C (13.20 g/kg DM), while the highest propionic acid productions were in Controltreatment at 35°C (0.37 g/kg DM).
