[ 1 ] - Effect of Tofu Wastewater Addition on the Growth and Carbohydrate-Protein-Lipid Content of Spirulina platensis (RESEARCH NOTE)

This study was conducted to investigate the effect of tofu wastewater (TW) addition to the growth medium on the growth of Spirulina platensis. The TW addition was varied in range of 0 – 8 %v/v. The results showed that the growth rate (μ) of S. platensis at TW addition of 0, 2, 4, 6, 8 %v/v was 0.007, 0.084, 0.074, 0.088, 0.086 mg/L/d, respectively. The medium with TW content of 6 %v/v (carbon:n...

[ 2 ] - Kinetics Studies Impact of Initial pH and Addition of Yeast Saccharomyces cerevisiae on Biogas Production from Tofu Wastewater in Indonesia

The purpose of this work was to study the effect of initial pH and yeast Saccharomyces Cerevisiae on biogas production from tofu wastewater (TW). The initial pH was varied in ranging of 5 – 9 in substrate without yeast (T5-T9) and with yeast (TY5-TY9). The results showed that optimum initial pH was 8. The maximum biogas was resulted in T8 (275 mL) and TY8 (421 mL). Yeast addition increased tota...

[ 3 ] - Effect of Total Solid Content to Biogas Production Rate from Vinasse (RESEARCH NOTE)

Vinasse that has high COD and total solid content is bottom of distillation from unit of bioethanol production Vinasse treatment using anaerobic digestion produced biogas. This research used anaerobic digester-laboratory scale at room temperature and batch system. The purpose of this research was investigation the effect of total solid content to biogas production rate from vinasse, pH profil a...
