Research ArticleOpen accessPhrase in the titleAdvances in Menaquinone-7 Production by Bacillus subtilis Natto: Fed-Batch Glycerol AdditionAydin Berenjian, Raja Mahanama, Andrea Talbot et al.Menaquinone-7 was produced by fermentation mainly using Bacillus subtilis species. Due to the low concentration of menaquinone-7 in fermentation processes and the associated expense of recovering the menaquinone-7, it was desirable to improve the fermentation concentration. The aim of this study was to determine the effect of fed-batch glycerol addition in the production of menaquinone-7 during the fermentation of Bacillus … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 10,539 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsProduction of Bacillus Subtilis as Biological Fertilizer by Biotransformation of Corn Steep LiquorXiaojie Ren, Baoyue Liu et al.Corn steep liquor is a kind of intractable organic waste liquidproduced during the processing of corn starch. But it is rich in nutrients,soluble protein, and amino acids and it could be used as a nitrogen source inthe fermentation industry. Many starch processing enterprises cannot directlyutilize corn steep liquor and choose to discharge it directly, thus causingenvironmental pollution. Studies have shown … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 10 Nov 2022 · 7,382 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Soft Sensor Modelling of Biomass Concentration during Fermentation using Accurate Incremental Online v-Support Vector Regression Learning AlgorithmBinjie Gu, Feng PanIn order to model real fermentation process, a soft sensor modelling of biomass concentration during fermentation using accurate incremental online ν-Support Vector Regression (ν-SVR) learning algorithm was proposed. Firstly, an accurate incremental online ν-SVR learning algorithm was proposed. This algorithm solved the two complications introduced in the dual problem based on the equivalent formulation of ν-SVR. Moreover, it addressed the … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 3 · 8 Aug 2015 · 7,327 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImprovement on Extracellular Production of Recombinant Burkholderia cepacia Lu10-1 Lipase by Escherichia coliYao Zhang, Yuanda Song, Lu Wang, Qing LiuThe purpose of this study was to investigate several strategies on enhancing extracellular production of recombinant lipase from Burkholderia cepacia Lu10-1 in recombinant Escherichia coli BL21(DE3). In the present study, a fed-batch fermentation strategy for the excellular production of lipase by E. coli has been established. First of all, different induction methods (including selection of inducers, inducer concentration, induction temperature … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 30 May 2018 · 11,539 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWeissella cibaria Fungistatic Activity against Fusarium spp. affecting Yellow PitahayaLeidy Johana Valencia-Hernández, Karina López-López, Liliana Serna-CockFungistatic activity of a Lactic-Acid Bacteria (LAB) was assessed in vitro while isolated from its rumen fluid, against Fusarium oxysporum and Fusarium fujikoroi, basal-rot related species in yellow pitahaya. Fed batch was used to reproduce said LAB. Fungistatic activity kinetic tests were performed on the ferment (S1) and on two of the fractions obtained through centrifugation, supernatant (S2) and biomass … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 10 Dec 2016 · 7,978 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnzymatic Hydrolysis of Pretreated Kenaf using a Recombinant Xylanase: Effects of Reaction Conditions for Optimum Hemicellulose HydrolysisNur Izyan Wan Azelee, Jamaliah Md Jahim, Ahmad Fauzi Ismail et al.An efficient hemicellulose hydrolysis has now become a crucial step for xylooligosaccharides production for food additives and nutraceuticals industries. In this study, xylanase hydrolysis of pretreated hemicellulosic kenaf (Hibiscus cannabinus) for substantial hemicellulose hydrolysis was demonstrated. Experiments were performed primarily to investigate the effect of several critical reaction conditions towards the enzymatic hydrolysis of the pre-treated kenaf. The effects of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 28 Apr 2016 · 7,816 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDynamic Mathematical Modelling of Reaction Kinetics for Cyclodextrins Production from Different Starch Sources Using Bacillus macerans Cyclodextrin GlucanotransferaseSyahinaz Shahrazi, Suryani Saallah, Mohd Noriznan Mokhtar et al.This study relates to the mathematical modelling of enzymatic production of Cyclodextrins (CDs) by Cyclodextrin Glucanotransferase (CGTase) from Bacillus macerans. The experiments were carried out in batch mode using different starch sources and the results were used to estimate unknown parameters using linearization and dynamic simulation methods. α- and β-CD produced from tapioca were found to give the highest Michaelis-Menten … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 7,909 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Influence of Total Solid Contents on Biogas Yield from Cattle Manure Using Rumen Fluid InoculumBudiyono, I. N. Widiasa, S. Johari, SunarsoProblem statement: Anaerobic digestion was a biological method used to convert organic wastes into biogas and a stable product for land application without adverse environmental effects. The biogas produced could be used as an alternative renewable energy source. The aim of this study was to analyze the influence of total solid contents on biogas yield from cattle manure using fluid … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 12,101 accessesView PDF Cite
