Research ArticleOpen accessIn the keywordsTemperature Optimization for Bioethanol Production from Corn Cobs Using Mixed Yeast StrainsClarence S. Yah, Sunny E. Iyuke, Emmanuel I. Unuabonah et al.Problem statement: Dilute sulphuric acid and enzymatic hydrolysis methods were used for sugar extraction. Xylose and glucose sugars were obtained from corn cobs. Approach: Acid hydrolysis of corn cobs gave higher amount of sugars than enzymatic hydrolysis. Results: The results showed that optimal temperature and time for sugar fermentation were approximately 25°C and 50 h by two yeast strains (S. … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 30 Jun 2010 · 9,339 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsRemediation of Methyl Tert-Butyl Ether (MTBE) Contaminated Water by Using In situ Catalytic and Biological Combined TechniquesA. Nikpay, H. Kazemian, M. SadeghiThe hydrolysis reaction of Methyl Tert-Butyl Ether (MTBE) into biodegradable products was studied on as-synthesized and commercial H-MFI zeolites. The effect of synthesis procedure and SiO2/Al2O3 ratio was investigated. The results obtained were indicated that H-MFI zeolites were effective in MTBE hydrolysis and increasing of the Si/Al ratio promotes the hydrolysis reaction. The amount of produced TBA was always lower … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,634 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPhysiochemical Properties of Sago Starch Modified by Acid Treatment in AlcoholP.H. Yiu, S.L. Loh, A. Rajan et al.Sago starch is usually chemically modified to overcome and improve the unstable properties of native sago starch during processing. In this study, sago starch was treated in hydrochloric acid in the presence of methanol, ethanol and 2-propanol at 450C for 1 hour. Granule size, granular structure and solubility of the modified starch were investigated. Results showed that recovery yields of … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 8,909 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCloning of the Endoglucanase Gene from a Bacillus amyloliquefaciens PSM 3.1 in Escherichia coli Revealed Catalytic Triad Residues Thr-His-GluZeily Nurachman, Sari Dewi Kurniasih, Ferra Puspitawati et al.Problem statement: An Indonesian marine bacterial isolate, Bacillus amyloliquefaciens PSM 3.1 was isolated for hydrolyzing cellulose. A 1500-bp nucleotide fragment was amplified from the chromosomal DNA by the use of primers directed against the conserved sequence of Bacilli endoglucanase genes obtained from GenBank. Approach: The fragment was cloned and expressed in Escherichia coli. Results: The endoglucanase gene (eglII gene) had … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,724 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnaerobic Fermentation for Ceftriaxone Sodium Degradation in Excess Sludge: pH-Dependent Performance, Metabolite Formation, and Microbial Community DynamicsWeiwei Li, Hong Niu, Yonghui Zhang et al.The accumulation of ceftriaxone sodium (CTX), a third-generation cephalosporin antibiotic, in wastewater and sludge poses significant environmental and health risks, necessitating effective degradation strategies. This study investigated anaerobic fermentation of excess sludge (12,000-14,000 mg/L) spiked with 15 mg/L CTX under varying pH conditions (4, 7, 10, 12) to evaluate sludge reduction, metabolite formation, and microbial community dynamics. Results demonstrated that … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 31 Jul 2026 · 857 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Zein-Fucoidan Nanoparticles Loaded with Curcumin on the Maillard Reaction Between Casein and LactoseShiyang Li, Yufan Liu, Yuanda Song et al.The influence of curcumin-encapsulated Zein-Fucoidan Nanoparticles (CZFNPs) on the formation of Maillard reaction products (MRP) at the early, intermediate, and advanced stages in a casein-lactose (CN-Le) reaction system was systematically studied. As controls, the effects of Zein-Fucoidan Nanoparticles (ZFNPs) and free Curcumin (Cur) were also evaluated. The results showed that CZFNPs effectively inhibited the formation of fructosamine, Glyoxal (GO), as … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 30 Jul 2026 · 605 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBioethanol Production from Graminoid Weeds in Bayero University Kano: A Potential Feedstock for Future Sustainable Aviation Fuel ApplicationsAdam Salihu Kila, Sa’idu Hassan Musa, Umar Aliyu Ahmed et al.This study evaluates the potential of selected graminoid weeds from Bayero University, Kano (BUK), Nigeria, as feedstock for bioethanol production. Ten (10) abundant weed species, including Cenchrus species, Cynodon dactylon, and Setaria barbata, were subjected to physicochemical pretreatment (ultrasonication, hydrothermal treatment, and enzymatic hydrolysis) followed by fermentation using Bacillus subtilis, Saccharomyces cerevisiae, and their co-culture. Pretreatment significantly enhanced reducing sugar … …Energy Research Journal, Vol. 15, Issue 1 · 15 Jul 2026 · 1,170 accessesView PDF Cite
