2019/7/29/ · Vinegar is generally defined as a sour or acidic liquid obtained from a two-step fermentation process [10, 18, 40].The fermentation process utilizes yeast for the anaerobic fermentation of sugar to ethanol and acetic acid bacteria (AAB) for the aerobic oxidation of ethanol to acetic acid (Fig. 1) [10, 40, 86].As a key metabolite, acetic acid is
2023/12/1/ · The serum bottles were placed into a water-batch shaker for anaerobic fermentation at 140 rpm and 35 °C for 7 days. The fermentation liquid was collected by centrifugation at 8000 rpm for 10 min, which would be further used as supplementary carbon source for the inverted A 2 /O reactor. The fermentation liquid was stored at 4 °C before
2022/7/15/ · This study assessed the feasibility of a novel vacuum-enhanced anaerobic digestion technology, referred to as IntensiCarb TM (IC), under mild vacuum pressure (110 mbar), compared to a control (conventional fermenter), and evaluated the impact of the vacuum on the activities of various microbial groups. Both fermenters (test and control)
2022/1/1/ · There are four types of commonly used solid-state fermenters; tray, packed bed, horizontal drum, and fluidized bed reactors, which vary based on the aeration and agitation strategies (Berovic, 2019) (Fig. 5.1).Tray fermenters are the most basic solid-state fermenters that are commonly used in traditional solid-state fermentation of foods in
The fermentation process can be classified as anaerobic fermentation, aerobic fermentation and facultative fermentation according to the characteristics of the strain.
2016/11/11/ · Microbial fermentation of renewable feedstocks is an established technology in industrial biotechnology. Besides strict aerobic or anaerobic modes of operation, novel innovative and industrially applicable fermentation processes were developed connecting the advantages of aerobic and anaerobic conditions in a
2021/12/1/ · Therefore, the concentrations of NH 3-N and COD were higher in the early stage of dry-AD, and they decreased as fermentation progressed and organic matter was gradually degraded. 3.7. Microbial characteristics during dry anaerobic digestion3.7.1. Bacteria alpha-diversity and taxonomic analysis
2022/2/15/ · The cumulative profiles of hydrogen sulfide generation from WAS anaerobic fermentation in the presence of KMnO 4 at different dosages are shown in Fig. 1.It can be found that KMnO 4 addition efficiently reduced H 2 S production. The higher the KMnO 4 addition, the lower the H 2 S production. With an increase of KMnO 4 from 0 to
Aerobic fermenters: Aerobic fermenters are used to grow microorganisms that require oxygen to grow. Anaerobic fermenters: Anaerobic fermenters are used to cultivate microorganisms that can grow without oxygen. UPM Is Leading Industrial and Laboratory Bioreactor & Fermenter Manufacturer and Indian Exporter and Supplier In Indore India.
2021/3/1/ · Anaerobic acid-producing fermentation is regarded as a promising and sustainable technology for simultaneously sludge reutilization and advanced nutrient removal (He et al., 2021; Jiang et al
Manufacturer of Environmental Engineering apparatus - Laboratory Anaerobic Digester, Aerobic Digester Tank offered by Innovative Research Equipments, Kurukshetra, Haryana.
This Special Issue will therefore exclusively focus on innovative research outputs, short communications, and perspective reviews on the production of biofuels and high-value biorenewables via anaerobic fermentation to support net neutrality. The use of biomass pre-treatments to support/enhance fermentation product yields are also of interest.

In this study, an interesting phenomenon was found in a sludge anaerobic fermenter with a dynamic membrane (DM) which could not only enhance SCFAs production but also retain most SCFAs in fermenter. The separation factor of DM for NH 3-N/SCFAs and PO 4 3-/SCFAs throughout the DM development were about 40 and 80, respectively. Analysis …
