Jan 15, 2019 · High-efficiency production of artemisinic acid via yeast fermentation has become a milestone for the application of synthetic biology to the production of natural plant products 1,2.
The continuously operated system did not improve the efficiency (volumetric productivity of the immobilized cells 30.7 g l(-1) h(-1)). Conclusions: We demonstrated Z. mobilis capability, entrapped into LentiKats, in the cost-efficient batch system of ethanol production.
Mar 15, 2023 · In recent years, cardiovascular and cerebrovascular diseases have been the focus of several studies. In this study, oyster protein hydrolysate was produced via enzyme hydrolysis and used as a fermentation substrate to ferment recombinant strain PSP2 to produce nattokinase. Using the synergism strategy, fermentation products with fibrinolytic and angiotensin I-converting enzyme (ACE) inhibitory
Jun 1, 2022 · Analysis of the mass balance showed that ferulic acid detoxification by AEPA 250 had a high removal efficiency of 94.393% with a low glucose and xylose loss of 2.532% and 8.219%, respectively. A higher 277.551 mg/L bioethanol concentration and 76.005% glucose consumption rate in the SSBP system were obtained compared to non-detoxified sample.
Experiments show that the transformation efficiency of glutamate to glutamine is more than 95%. Because of the high cost from ATP, a system coupling GS with yeast for ATP regenaration was established. In this system, GS utilizes ATP released by yeast fermentation to synthesize L-glutamine.
Feb 1, 2024 · The combined system increased the total biohydrogen production by 41 % compared to the fermentation system alone, with a total biohydrogen production rate of 0.24 m 3 H 2 /(m 3 ·d), resulting in electrical energy generation and improved energy recovery efficiency. Bioelectrochemical systems and fermentation coupling systems could affect the
Through organic coordination of sensors, system execution devices and soft boundary control algorithms, the key factors for black tea fermentation are subject to parameterized control, thus finally achieving the goal of minimal fermentation process with production efficiency improved.
May 29, 2018 · We hypothesized that yeast cells subjected to plasma treatment could develop increased robustness and resilience and thus improve the efficiency of fermentation.
Nov 4, 2022 · The biosynthesis of collagen has ushered in the dawn in the twenty-first century. It is a promising option to express collagen using animal and plant cells, yeast, and Escherichia coli systems, and to conduct large-scale preparation with high-density fermentation technology (Xiang et al. 2021).
Nov 1, 2023 · The fermentation-separation coupling method exhibits promise for achieving high-efficiency production (Ashby, Solaiman & Foglia, 2008). Notably, previous work had demonstrated that semi-continuous fermentation based on SLs in-situ separation was an effective means of improving productivity and yield ( Chen et al., 2022 ).
Jun 15, 2023 · The use of solid-state fermentation (SSF) is also addressed as a potentially low-cost production system, amenable to customization and employing inexpensive feedstocks as substrate. Keywords: enzyme engineering, synthetic biology, precision fermentation, gene editing, food industry, plant proteins
Sep 14, 2022 · In the era of sustainable development, the use of cell factories to produce various compounds by fermentation has attracted extensive attention; however, industrial fermentation requires not only efficient production strains, but also suitable extracellular conditions and medium components, as well as scaling-up.
Nov 23, 2022 · The aim of this study was to examine the effects of a semi-membrane covering on the spatial homogeneity and efficiency of fermentation in aerobic composting systems. In the covered group, the pile was covered with a semi-membrane, while in the non-covered group (control group), the pile was uncovered.
Sep 1, 2017 · The present advanced sequential fed-batch fermentation process is extremely efficient due to the high cell density and the presence of 18 g/L NaNO 3 and 2 mg/L FeSO 4 ·7H 2 O with enhanced mass-transfer efficiency, presenting a new strategy to improve the fermentation level of rhamnolipids.
Apr 10, 2018 · Fed-batch, continuous, and batch fermentation systems can be selected for high efficiency. Continuous and fed-batch systems can handle substrate restriction amid fermentation procedures. Higher efficiency also can be achieved by the immobilization of cells, which can be derived incrementally from the biomass collection in the bioreactor
