2024/3/1/ · Electrochemical technology is applied to fermentation to strengthen the electron transfer process, which is a new method of coupling electrochemical and
2018/3/10/ · As with PLAFRACTOR, all the fermentation operations could possibly be carried out, aseptically, in a single unit. The horizontal expansion of the bioreactor (100–400 cm or 150–300 cm) was greater than the vertical height (1 m, 2 or 2.5 m) and was estimated to replace 50–100, 2 kg plastic SSF bags.
2024/4/21/ · The ethanol fermentation reaction is shown in Figure 8.4.1 8.4. 1. In the first reaction, the enzyme pyruvate decarboxylase removes a carboxyl group from pyruvate, releasing CO 2 gas while producing the two-carbon molecule acetaldehyde. The second reaction, catalyzed by the enzyme alcohol dehydrogenase, transfers an electron from
2024/5/1/ · It is imperative to note that lactic acid-type fermentation liquid (LAFL) markedly differs from VFA-rich fermentation liquid. During the fermentation process of food waste, lactic acid is preferentially produced during glycolysis due to its lower Gibbs free energy requirement compared to VFA (Holtzapple et al., 2022, Zhou et al., 2018).
2023/11/16/ · Brewer’s spent grain (BSG) is a major by-product in the beer-brewing process which contributes to 85% of the entire generated by-product in the brewing process. BSG is rich in proteins, and most of the malt proteins (74–78%) remain insoluble in BSG after the mashing process. Solid-state fermentation (SSF) is a promising bioprocess that
Regularly adding biogas slurry into fermentation reactors is an effective way to enhance hydrogen or methane production. However, how this method affects the production of valuable organic acids and alcohols is still being determined. This study investigated the effects of different addition ratios on semi-continuous fermentation reactors using
2017/4/25/ · This work summarizes the diversity of applications of solid state fermentation to valorize biomass regarding alternative energy and environmental
However, this method exhibits several disadvantages, including low efficiency and serious waste generation, which makes it difficult to meet the current market demand. With the rapid development of synthetic biology and the deepening of high-density fermentation technology, the collagen preparation by biosynthesis strategy emerges as the times
2022/12/12/ · Solid-state fermentation (SSF) is part of the pathway to consolidate waste as a relevant alternative for the valorization of organic waste. The objective of SSF
Bacteria of several gram-positive genera, including Lactobacillus, Leuconostoc, and Streptococcus, are collectively known as the lactic acid bacteria (LAB), and various strains are important in food production.During yogurt and cheese production, the highly acidic environment generated by lactic acid fermentation denatures proteins contained in milk,
2023/8/22/ · In this case the substrate was efficiently converted via fermentation into butanoic acid, hexanoic acid or octanoic acid. 63 The product distribution depends on the waste substrate and fermentation conditions, with corn beer mainly yielding hexanoic acid or octanoic acid and corn silage yielding butyric acid. The fermentation broth is then
2 天之前 · The most sustainable feedstocks for industrial fermentation. Food industry waste. Startup Hyfe extracts sugar from wastewater produced by food manufacturing facilities, turning it into a standardised microbe ‘feed’ for precision fermenters to use as an input. Hyfe’s method of manufacturing this microbe feed doubles as a water treatment
2023/2/22/ · The fed-batch cultivation is in many ways a benchmark for fermentation processes, and it has been an attractive choice for the biotechnological production of various products in the past decades. The majority of biopharmaceuticals that are presently undergoing clinical trials or are available on the market are manufactured through fed …
