“…Previous research reported that bioethanol content from Saccharina japonica with the Simultaneous Saccharification and Fermentation (SSF) method using a concentration of 10% Pichia angophorae and S. cerevisiae at 30 °C for 64 h resulting in an bioethanol content of 1.00% (9.8 mL / L) [36]. Another research reported that the highest bioethanol content in simultaneous saccharification and fermentation (SSF) was obtained on 8 days fermentation at 35 °C and pH 4.8 with bioethanol content of 1.05% [23].…”

This paper describes about the potential application of renewable energy sources from biomass (seaweed waste) to replace fossil fuels combustion which produced CO2 emission and heavy metal pollution. The objective of the research is to utilize the seaweed solid waste from agar production industry for bioethanol feedstock. The enzymatic method was carried out for glucose production with the addition 1% of surfactant Tween 20 during the saccharification process of three kinds of substrate concentration (20, 25, 30% dw) and 10 FPU/g substrate for the cellulose concentration and used S. cerevisae as yeast in the fermentation process for bioethanol production. The result showed that the highest reducing sugar value (122.4 mg/mL) and 2.86% for the bioethanol content were from 30% dw treatment of substrate concentration of solid agar waste. Therefore, the waste from agar industry is a potential raw material to be used as biofuel and could reduce the heavy metal problems.

CuO pricky microspheres have been synthesized without additives by calcination after hydrothermal treatment at [Formula: see text]C for 6[Formula: see text]h. The product was characterized by SEM, TEM, EDS, etc. The unique pricky microspheres were formed with NH4HCO3 and urea as precipitators. Through a series of reaction experiments, the possible formation mechanism of nucleation, growth and secondary growth was proposed. With the assistance of H2O2, the degradation rate of RhB aqueous solution reached 87.16% after 50 min by simulated visible light degradation, which proved the good photocatalytic performance of the CuO pricky microspheres. After four cycles of degradation experiments, the degradation rate of RhB aqueous solution is still above 80%. The radical capture experiments showed that the main active groups in the degradation process were ⋅OH and ⋅O2−, and the mechanism of photocatalytic degradation of Rhb was proposed.
