Integrated management of hemicellulosic fraction and its economical transformation to value-added products is the key driver towards sustainable lignocellulosic biorefineries. In this aspect, microbial cell factories are harnessed for the sustainable production of commercially viable biochemicals by valorising C5 and C6 sugars generated from agro-industrial waste. However, in the terrestrial ecosy...... hiện toàn bộ
A simple method to control glycolytic flux for the design of an optimal cell factoryBiotechnology for Biofuels - Tập 10 - Trang 1-10 - 2017
Jae Hyung Lim, Gyoo Yeol Jung
A microbial cell factory with high yield and productivity are prerequisites for an economically feasible bio-based chemical industry. However, cell factories that show a kinetic imbalance between glycolysis and product formation pathways are not optimal. Glycolysis activity is highly robust for survival in nature, but is not optimized for chemical production. Here, we propose a novel approach to b...... hiện toàn bộ
Quantitative analysis of the effects of morphological changes on extracellular electron transfer rates in cyanobacteriaBiotechnology for Biofuels - Tập 13 - Trang 1-14 - 2020
Tonny I. Okedi, Adrian C. Fisher, Kamran Yunus
Understanding the extracellular electron transport pathways in cyanobacteria is a major factor towards developing biophotovoltaics. Stressing cyanobacteria cells environmentally and then probing changes in physiology or metabolism following a significant change in electron transfer rates is a common approach for investigating the electron path from cell to electrode. However, such studies have not...... hiện toàn bộ
A simple strategy to effectively produce d-lactate in crude glycerol-utilizing Escherichia coliBiotechnology for Biofuels - Tập 12 - Trang 1-9 - 2019
Yao-De Wang, Jin-Yi Liao, Chung-Jen Chiang, Yun-Peng Chao
Fed-batch fermentation has been conventionally implemented for the production of lactic acid with a high titer and high productivity. However, its operation needs a complicated control which increases the production cost. This issue was addressed by simplifying the production scheme. Escherichia coli was manipulated for its glycerol dissimilation and d-lactate synthesis pathways and then subjected...... hiện toàn bộ
Photosynthetic conversion of CO2 to farnesyl diphosphate-derived phytochemicals (amorpha-4,11-diene and squalene) by engineered cyanobacteriaBiotechnology for Biofuels - Tập 9 - Trang 1-12 - 2016
Sun Young Choi, Hyun Jeong Lee, Jaeyeon Choi, Jiye Kim, Sang Jun Sim, Youngsoon Um, Yunje Kim, Taek Soon Lee, Jay D. Keasling, Han Min Woo
Metabolic engineering of cyanobacteria has enabled photosynthetic conversion of CO2 to value-added chemicals as bio-solar cell factories. However, the production levels of isoprenoids in engineered cyanobacteria were quite low, compared to other microbial hosts. Therefore, modular optimization of multiple gene expressions for metabolic engineering of cyanobacteria is required for the production of...... hiện toàn bộ
Aerobic and sequential anaerobic fermentation to produce xylitol and ethanol using non-detoxified acid pretreated corncobBiotechnology for Biofuels - Tập 7 - Trang 1-9 - 2014
Ke-Ke Cheng, Jing Wu, Zhang-Nan Lin, Jian-An Zhang
For economical bioethanol production from lignocellulosic materials, the major technical challenges to lower the production cost are as follows: (1) The microorganism should use efficiently all glucose and xylose in the lignocellulose hydrolysate. (2) The microorganism should have high tolerance to the inhibitors present in the lignocellulose hydrolysate. The aim of the present work was to combine...... hiện toàn bộ
Whole-genome de novo sequencing, combined with RNA-Seq analysis, reveals unique genome and physiological features of the amylolytic yeast Saccharomycopsis fibuligera and its interspecies hybridBiotechnology for Biofuels - Tập 9 - Trang 1-22 - 2016
Jin Ho Choo, Chang Pyo Hong, Jae Yun Lim, Jeong-Ah Seo, Young-Suk Kim, Dong Wook Lee, Sin-Gi Park, Gir Won Lee, Emily Carroll, Yin-Won Lee, Hyun Ah Kang
Genomic studies on fungal species with hydrolytic activity have gained increased attention due to their great biotechnological potential for biomass-based biofuel production. The amylolytic yeast Saccharomycopsis fibuligera has served as a good source of enzymes and genes involved in saccharification. Despite its long history of use in food fermentation and bioethanol production, very little is kn...... hiện toàn bộ
