2017/11/1/ · (II) Aerobic cultivation: the cells were cultivated at 37 °C and 220 rpm in a shaking incubator. (III) Aerobic-anaerobic shift cultivation: flasks were transformed into an anaerobic workstation after a certain period of aerobic cultivation. The method of oxygen removal and anaerobic cultivation was the same as described in (I). 2.3.
2023/11/23/ · In order to make 1000 l of a hoppy beer, 27 000 l of water are used to grow the hops that are added to the brew. Using Yops TM, only 11 l of water are used to make the aroma needed for the same amount of beer. The carbon footprint of producing, storing, and transporting the hops that are used to brew 1000 l of hoppy beer can be up to
2019/7/16/ · A fermentation process development usually starts with lab scale with bench-top bioreactors (1–50 L) or even shake flasks (100–1000 mL) and microbial cells (few mL). After optimization has convinced that a bioprocess is feasible, then a pilot-scale process (50–10,000 L) is designed and implemented to establish the optimal operating
The process uses a defined medium and two distinct fermentation phases: aerobic growth to an optical density of about 30, followed by nongrowth, anaerobic production. Strain YYC202 (aceEF pfl poxB pps) generated 90 g/liter lactate in 16 h during the anaerobic phase (with a yield of 0.95 g/g and a productivity of 5.6 g/liter . h).
Abstract. Large-scale production of recombinant proteins in Escherichia coli requires growth of cells in fermentors. This unit lists E. coli strains appropriate for use in fermentors, and also discusses important characteristics of fermentation equipment. Production of recombinant proteins in batch fermentations is described, as are variations
2021/3/26/ · For instance, in a study for optimization of β-amyrin formation by engineered yeast in fed-batch fermentation, the most favorable inoculum size was reported as initial OD 600 of 0.3 . Moreover, in another study, inoculum size of 5.0 and 5.2% ( v / v ) with S. cerevisiae strain BY4741 and 8.1 and 2.6% ( v / v ) for strain EGY48 were
2014/5/23/ · Mixed-acid fermentation end products have numerous applications in biotechnology. This is probably the main driving force for the development of multiple strains that are supposed to produce individual end products with high yields. The process of engineering Escherichia coli strains for applied production of ethanol, lactate, succinate,
2021/11/1/ · This result suggests that duplications of the XYL cassette and TKL1 together are necessary for respiration-independent aerobic xylose fermentation. When we engineered two copies of the XYL cassette and TKL1 into the cox15Δ strain containing wild-type HOG1, ISU1, and IRA2 (denoted as “3WT”), the strain did not metabolize xylose

The food-, pharma- and cosmetics industry uses bio-reactors, also called fermenters, to ferment organic substances by adding bacteria, fungi or enzymes. Our customers efficiently and safely cultivate cells and microorganisms as well as yeast and bacteria at the Ruland-bio-fermenters and bio-reactors. The fermentation processes are highly
Here, we evolved respiration-deficient S. cerevisiae strains that can grow on and ferment xylose to ethanol aerobically, a trait analogous to the Crabtree/Warburg Effect for glucose. Through genome sequence comparisons and directed engineering, we determined that duplications of genes encoding engineered xylose metabolism enzymes, as well as
2022/2/1/ · Fermentation offers solutions for both problems. Precision fermentation can aid in the synthesis of various compounds such as vitamins, polyphenolic compounds, anti-freeze proteins and glycolipids, which can be incorporated into the culture media to improve the nutritional content and maintain the quality of the resultant CM product. 2.4.1.
2024/2/1/ · The precision fermentation process relies on harnessing the potential of microflora and its metabolism to generate specific compounds. By meticulously controlling and adjusting the environmental conditions to which a microorganism is exposed (including the temperature and the available substrate), specific by-products can be induced in their
2017/1/30/ · Vitamin B 12 is an essential vitamin that is widely used in medical and food industries. Vitamin B 12 biosynthesis is confined to few bacteria and archaea, and as such its production relies on microbial fermentation. Rational strain engineering is dependent on efficient genetic tools and a detailed knowledge of metabolic pathways, regulation of …
