Optimization of Biogas Output From Biomaterials via Python and ANN, and Its Digester Design and Fabrication

open access: yesEnergy Science &Engineering, Volume 13, Issue 11, Page 5574-5586, November 2025.
Schematic approach of the biogas production process and its utilization. ABSTRACT Due to the instability of the energy sector leading to the high cost of purchasing non‐biomass fuel, there is a need to investigate an ideal biomass fuel that can be utilized in place of non‐biomass fuel and whose biomaterials are within reach.

Microwave Processing at the 915 MHz Frequency for Efficient Cleavage of Cellulose and Lipids in Vegetable and Meat Wastewater Treatment

open access: yesJournal of Food Science, Volume 90, Issue 11, November 2025.
ABSTRACT Meat and vegetable processing wastewaters are challenging to treat due to high concentrations of recalcitrant organic compounds—such as fats, oils, and cellulose—that resist conventional degradation. This study systematically evaluated the use of 915 MHz microwave (MW) processing, focusing on the effects of specific energy flux (SEF, in J/kg·s)

EFFECT OF AMMONIA-NITROGEN ON ACIDOGENESIS IN ANAEROBIC DIGESTION

open access: yesDoboku Gakkai Ronbunshu, 2000
嫌気性消化における炭水化物とタンパク質の分解に及ぼすアンモニアの影響を検討するため, 基質にデンプンとペプトンを用い, アンモニア性窒素濃度を変化させた回分実験を行った. その結果, ペプトンの分解速度は, ほとんど影響を受けなかったが, デンプンの分解速度は, アンモニア性窒素濃度の増大とともに大きく減少した. さらに, 炭水化物の代謝に及ぼすアンモニア性窒素の影響を検討するために, グルコースで培養した酸生成細菌を用いて回分実験を行ったところ, アンモニア性窒素濃度の増大に伴い, 分解したグルコース当たりの酪酸生成量は減少した. 一方, エタノールの生成は, アンモニア性窒素濃度の増大に伴い, 増加する傾向を示した.

Enforcing ATP hydrolysis enhanced anaerobic glycolysis and promoted solvent production in Clostridium acetobutylicum

open access: yesMicrobial Cell Factories, 2021
Background The intracellular ATP level is an indicator of cellular energy state and plays a critical role in regulating cellular metabolism. Depletion of intracellular ATP in (facultative) aerobes can enhance glycolysis, thereby promoting end product ...
