Simultaneous Saccharification and Fermentation of Wheat Starch for Bioethanol Production

Fermentation, Год журнала: 2025, Номер 11(2), С. 80 - 80

Опубликована: Фев. 6, 2025

Bioethanol is a renewable, environmentally-friendly biofuel conventionally produced through the alcoholic fermentation of sugary or starch-rich substrates by microorganisms, commonly Yeast Saccharomyces cerevisiae. Intermediates industrial wheat flour wet milling processing to starch, such as A-starch and B-starch milk, are cost-effective, abundant, non-seasonal feedstocks for bioethanol production. This study evaluates production from milk mixtures these two in different ratios (1:3, 1:1, 3:1) using cold hydrolysis procedures at 65 °C: (i) simultaneous liquefaction saccharification (SLS) followed fermentation, (ii) alpha-amylase (SSF). The results demonstrated that SSF SLS equally efficient reaching high ethanol yield 53 g per 100 starch 93% conversion all investigated substrates. Lower levels non-starch components which typically contribute volatile by-product formation, allowed clear distillate profiles terms lower content aldehydes, methanol, acidity, enhancing purity compared milk. Mixing high-quality with low-cost enables higher yield, improved quality, energy savings industrial-scale applications.

ABSTRACT Bioethanol, a sustainable energy solution derived from renewable biomass, has gained prominence, with corn stover emerging as substantial biomass resource in Indonesia. Corn stover, residue, is one of the top three agricultural wastes worldwide and abundantly available. However, significant portion burned fields rather than utilized for bioethanol production, whereas it potential feedstock. As world strives to realize environmentally friendly security, production can be solutions developed. Nonetheless, current immaturity technology causes large‐scale failure. The present paper comprehensively reviews technological aspects process optimization using feedstock comprising pretreatment, hydrolysis, fermentation, purification processes. According our critical review, ammonia fiber expansion (AFEX) pretreatment most effective conventional glucose yield up 90%. Moreover, ultrasound appears viable option nonconventional producing bioethanol. combining dilute aqueous produced 80.6% sugar output. Furthermore, enzymatic hydrolysis emerges saccharification, yielding 81.39%. fermentation saccharification co‐fermentation (SScF) method response surface methodology (RSM) could produce concentration 59.8 g/L 92.07% ethanol yield, respectively. This review also reveals that pervaporation best choice high purity > 99%. In addition, this reduce used by 6.6% lower, 24.2% lower carbon footprint, have lowest total capital costs compared molecular sieves extractive distillation. We believe article provide reference selecting further research.

As a typical forestry waste, bamboo has gained increasing attention for its potential applications. In order to optimize valorization, understanding the kinetic and thermodynamic parameters of pyrolysis combustion is crucial. this study, thermogravimetric analysis (TGA) was employed examine powder’s behaviors under different temperature ramps in nitrogen air environments, were evaluated using Flynn–Wall–Ozawa (FWO), Kissinger–Akahira–Sunose (KAS), Starink (STR) model-free approaches. The main findings are as follows. (1) thermogravimetry (TG) derivative (DTG) curves reveal that occurs three distinct stages: drying, devolatilization, carbonization. Similarly, also proceeds through char combustion. Notable differences ranges key stages observed between (2) activation energies during oxidative devolatilization stage notably lower compared those devolatilization. disparity energy even more pronounced third stage. (3) Thermodynamic shows endothermic non-spontaneous. It can be stably converted into value-added or process. This study provides essential data aid designing scaling up thermochemical conversion processes promote efficient valorization bioenergy.
