ABSTRACT

Utilization of available indigenous inoculants for solid state fermentation using available substrates is an innovative practice in biotechnology. This study determined the potential of rice culture starter (bubod) as an inoculant for rice bran substrate through solid-state fermentation (SSF). Specifically, it determined the volume of liquid extracts, the weight of fermented substrates, substrate fermentation rate, pH of the liquid extract and substrate of the different treatments at various fermentation durations, the difference among treatments and correlation of the variables. The complete randomized design (CRD)  with 3 replications was adopted in this study.  The different mixture ratios of rice starter culture and rice bran substrates were used as treatments with different fermentation durations. The different treatments were compared using the analysis of variance and the Pearson r to correlate the different variables. Results showed that the volume of liquid extract and fermentation rate of substrate increase with fermentation duration while the weight of substrates and pH decrease. The experimental treatments have a significantly higher volume of liquid extract, and substrate fermentation rate compared to those the control treatments. The fermentation duration is directly proportional to the liquid extract volume, substrate fermentation rate but inversely proportional to the weight of fermented substrates and pH. This study shows the potential of rice culture starter as inoculant of rice bran substrate to produce nutritive compounds through solid-state fermentation.
