Dec 11, 2023 · Fermentation is usually associated with low oxygen conditions, providing an alternative path for recycling NADH when oxygen cannot be used as electron acceptor. Based on these findings, they expect that aerobic fermentation may also be relevant in other well-aerated tissues and might need to be taken into account when attempting to engineer
Dec 15, 2023 · Low carbon footprint acidogenic fermentation was aimed to produce VFA, successfully used as a carbon source to produce PHA. The results demonstrated that it is possible to achieve the amount of PHA to have an economically viable process (0.37 g PHA/g VSS) without applying sludge pre-treatment or chemicals addition, thus limiting the indirect

May 1, 2024 · Our findings provide valuable insights into the mechanisms for reducing CO 2 emission between nonfermentable carbon sources and biopolymers, contributing to the establishment of carbon emission platforms for aerobic fermentation in third-generation biorefineries.
Jan 1, 2012 · Comparing with aerobic metabolism, anaerobic metabolism especially fermentation can lead to the production of a broad range of valuable chemicals which have great biotechnological implications. To apply and manipulate bacterial metabolic pathways towards the maximal production of the desirable products, the fundamental principles of maintaining
impeller systems with D/T ratios of 0.3 and 0.5. How-ever, at V. = 0.7 m. n–1, P drops more for the larger im-gpeller. re explicitly, P of the larger impeller is 82%gthat of the smaller impeller; a. d kla is about 91% that of the smaller impeller. Consequently, if the overall process is oxygen-limited.
Oct 12, 2023 · Aerobic composting, especially semipermeable membrane-covered aerobic fermentation, is known to be an effective method for recycling and reducing vegetable waste. However, this approach has rarely been applied to the aerobic composting of vegetable waste; in addition, the product characteristics and GHG emissions of the composting process have not been studied in-depth. This study investigated
Jun 7, 2024 · The addition of biochar in aerobic fermentation systems can reduce CH 4 emissions by 20.8%, N 2 O emissions by 50.3%, and NH 3 emissions by 16.2% 34,35 due to the porous structure and surface

Oct 9, 2018 · The present study aimed to determine the preservation characteristics, in vitro rumen fermentation profile and microbial abundance of silages, produced with mixtures of sweet sorghum (SS) and alfalfa (AF) in different ratios: 100:0 (Control), 75:25 (SA25), 50:50 (SA50), 25:75 (SA75) and 0:100 (SA100) on a fresh weight basis.
Feb 1, 2024 · The low-temperature hydrothermal method for preparing hydrochar can retain functional groups in biomass and provide a carbon source for subsequent aerobic fermentation. In this study, the microstructure and functional group properties of hydrochar prepared by a low-temperature hydrothermal method were evaluated.
Jul 12, 2023 · Organisms break down organic molecules, such as glucose, through the common processes of cellular respiration and fermentation (Figure 1). Cellular respiration is generally described as an aerobic process, requiring oxygen, which yields the most possible ATP generated from one molecule of glucose.
Feb 21, 2022 · Here we describe the development of a carbon-negative fermentation route to producing the industrially important chemicals acetone and isopropanol from abundant, low-cost waste gas feedstocks,
Oct 30, 2013 · In heterogeneous gas-liquid reactions, e.g., in aerobic fermentation, the liquid phase controls mass transfer processes due to the relative insolubility of gases. This limitation is minimized by the use of bubble column reactors due to its good oxygen transfer with low cost operation when compared to stirred tank reactors ( Kantarcia, Borakb
