Jul 14, 2023 · Fermentation is one of nature's best tools and has very notable functions including the recycling of organic nutrients and assisting with the availability of phosphates for plants and animals. Fermentation technology helped to sustain our species during the millennia when our sense of social culture was developing and valuably helped us to
Feb 1, 2024 · In addition, Redondas et al. found that HRT can have a dramatic effect on biohydrogen production using food waste as a fermentation substrate [67]. The reduction in fermentation time had a negative effect on the conversion of the substrate, while the highest biohydrogen production was achieved when the HRT was 0.5 h.
Mar 1, 2011 · When the sludge fermentation liquids were added to the A 2 O reactor, the removal efficiencies of TN and phosphorus in domestic wastewater were increased by 11.0% and 16.0%, respectively. This combined system with 2-step sludge alkaline fermentation overcame the operational problem in practice and realized sludge reduction and resource
Oct 5, 2021 · The fermentation process is dynamically changing, and the metabolic status can be grasped through real-time monitoring of environmental parameters. In this study, a real-time and on-line monitoring experiment platform for substrates and products detection was developed based on non-contact type near-infrared (NIR) spectroscopy technology. The prediction models for monitoring the fermentation
Electro-fermentation (EF) has been extensively studied for recovering hydrogen and phosphorus from waste activated sludge (WAS), while was limited for the further application due to the low hydrogen yield and phosphorus recovery efficiency. This study proposed an efficient strategy for hydrogen and
Electro-fermentation (EF) is a novel process that consists of electrochemically controlling microbial fermentative metabolism with electrodes. The electrodes can act as either electron sinks or sources that allow unbalanced fermentation. They can also modify the medium by changing the redox balance. Such electrochemical control exerts significant effects not only on microbial metabolism and
Jun 1, 2022 · The reduction of the glucose/xylose ratio created a stress for S. cerevisiae fermentation, and thus challenged glucose fermentation. Therefore, to increase the fermentation of glucose in the SSBP system, the production of xylose should be suppressed or an improved strain that utilizes two sugars should be developed ( Lee and Yu, 2020 ).
Figure 6.2.1 6.2. 1: Homolactic (lactic acid) fermentation. Note that the 2 NADH produced in glycolysis are reoxidized to NAD+ when their electrons are added to pyruvate to make the waste product lactate (lactic acid) (2021; Jeanne Kagle) Bacteria of several Gram-positive genera, including Lactobacillus, Leuconostoc, and Streptococcus, are
Jul 1, 2023 · Interestingly, two previous reports indicated that Candidatus Roizmanbacteria and Candidatus Pacebacteria can mediate carbon transport in fermentation system or act as a unique role in degrading complex organic matter (Chiriac et al., 2022, Geesink et al., 2020), which suggested that the RHS as a carbon source during ectopic fermentation can
Sep 14, 2022 · In a recent study, Wang et al. also predicted the bio-hydrogen fermentation conditions and analyzed the effect of critical parameters during fermentation by combining ANNs and a response surface methodology . ANNs also show great potential during fermentation process control.
Jul 1, 2024 · The results showed that nitrate photolysis significantly promoted the SCFAs production from WAS, and peaked at 280.7 mg/g VSS with 7-d fermentation with 150 mg N/L addition (150N-UV), which increased by 8.8-35.0 % and 10.7-23.3 % compared with other photolysis groups and sole nitrate groups.
Sep 16, 2021 · Imagine if we could redesign nature by making a house out of mushrooms, growing seafood in a lab, or even combatting cancer using targeted genes from broccoli. These possibilities exist with innovations in fermentation and synthetic biology.
Nov 1, 2023 · Excess sludge fermentation and the addition of sludge fermentation products could enhance the nitrogen removal, and excess sludge treatment was simultaneously achieved with external sludge reduction ratio of 39%–50% (Liu et al., 2021a, Zhang et al., 2022a). However, these processes required multiple reaction units, and each unit needed to be
The Low Fermentation Eating diet is easy-to-follow, completely nutritionally sustainable, and allows patients to return to eating that feels normal and not overly restrictive. Developed by Dr. Mark Pimentel and Dr. Ali Rezaie, Discover the benefits of low-fermentation eating with Goodlfe.
Feb 1, 2019 · Both fermentation time and culture ratio showed significant (p < 0.05) effects on reducing sugar content and increasing the ethanol content for alcoholic fermentation. The optimum fermentation conditions were 72 h of fermentation and using a S. cerevisiae : P. pulmonarius mycelia: V. volvacea mycelia culture ratio of 1:1:1, achieving a
