Summary: The study found that the optimal NaOH pre-treatment conditions for enzymatic hydrolysis of wheat straw to enhance reducing sugar yield were NaOH concentration of 1.0%, solid content of 5.0%, and pre-treatment time of 60 minutes. Optimization of parameters such as solid content, enzyme loading, temperature, pH, and hydrolysis time during enzymatic hydrolysis can significantly increase the yield of reducing sugars.

Summary: This study investigated the properties of hydrolysates obtained from acid and alkali hydrolysis for bio-hydrogen production. Results showed that 1.0% H2SO4 hydrolysate had the highest hydrogen production efficiency, while hydrogen production and metabolite distribution depended on the sugars and by-product composition in the hydrolysate.

Summary: This study examined the effects of different modification methods on defatted rice bran dietary fiber, with fermentation and enzymatic hydrolysis combined modification showing the most significant impact. The microstructural properties of the modified dietary fiber changed, while the crystal type remained generally unchanged. Glucose adsorption capacity was significantly improved with fermentation and enzymatic hydrolysis modification.

Summary: Efforts to improve lignocellulosic pretreatments have been costly in second-generation ethanol production, but high-concentration PEG shows promise in increasing ethanol production without the need for additional chemical or physicochemical pretreatments. Operational conditions in a study using high PEG concentrations and green coconut fiber as substrates showed increased ethanol production, with the addition of salts, yeast extract, or peptone further enhancing ethanol yield.

Summary: A chemical-bacterial process was developed to convert vegetable straw waste into valuable antifungal iturins. Microwave assisted hydrolysis with dilute acid was used to recover reducing sugars efficiently. The fermentation parameters were optimized to enhance iturin production, and the obtained extract exhibited strong antifungal activity against Alternaria alternata. This study demonstrates the potential of valorizing vegetable straw through this process.

Summary: Biochemical conversion of wheat straw was studied using hydrothermal pretreatment, enzymatic saccharification, and microbial fermentation. Different pretreatment conditions had significant effects on chemical composition, enzymatic digestibility, carbohydrate composition, inhibitory byproducts, furfural, and fermentability. Xylose concentration in pretreatment liquids increased with temperature up to 190 degrees C and then decreased.

Summary: Fermented rice bran using Lactiplantibacillus plantarum EM showed high cholesterol removal and strong antimicrobial activity. The resulting HFRB had effective cholesterol removal and antimicrobial activities against foodborne pathogens and spoilage fungi. The fermentation process improved the overall organoleptic quality, making HFRB a promising functional food candidate.

Summary: The aim of this study was to investigate the use of Chlorella sorokiniana SU-1 biomass grown on dairy wastewater-amended medium as a sustainable feedstock for the biosynthesis of 0-carotene and polyhydroxybutyrate (PHB) by Rhodotorula glutinis #100-29. Rigid cell walls of the microalgal biomass were broken down using 3% sulfuric acid and detoxified with 5% activated carbon. Fermentation using the detoxified microalgal hydrolysate (DMH) resulted in maximum biomass production of 9.22 g/L, with concentrations of PHB and 0-carotene reaching 897 mg/L and 93.62 mg/L, respectively. Upscaling to a 5-L fermenter increased biomass concentration to 11.2 g/L, with PHB and 0-carotene concentrations of 1830 mg/L and 134.2 mg/L.
