Sep 6, 2023 · Biofuels are the sustainable counterparts of fossil fuels to meet the increasing energy demands of the current and future generations. Biofuels are produced from waste organic residues with the application of mechanical, thermochemical and biological and processes. While mechanical and thermochemical conversion processes involve the use of heat, pressure, catalysts and other
Aug 3, 2023 · Stirrer glands and bearings. The most important factor of designing a fermenter is to maintain aseptic conditions inside the vessel. It is highly challenging in the case of pilot-scale fermenters. Therefore stirrer shafts are required. These stirrer shafts play an important role to seal the openings of a bioreactor.
The tower fermenter is an elongated non-mechanically stirred fermenter with aspect ratio of at least 6:1 for tubular section or 10:1 overall, through which there is unidirectional flow of gases. The tower fermenter used for citric acid production on a laboratory scale having height: diameter ratio of 16:1.
Jan 14, 2023 · Some examples of food waste fermentation include the production of (1) flavonoids and carotenoids from fruit or vegetable waste, (2) bioactive peptides from cereal processing waste and whey from cheese making, (3) antioxidative compounds from by-products of livestock and seafood processing (Martí-Quijal et al. Citation 2021; 4) enzymes
Sep 1, 2023 · Staged fermentation realizes the advanced treatment of food waste. • Staged fermentation provides suitable ethanol and VFAs for chain elongation. • n-Caproate production from food waste shows advantages in economy. • Microbiomes related to chain elongation are enriched.
Aug 31, 2023 · A bioreactor, or a fermentation vessel, is a device or system used to cultivate and produce biological. cells, tissues, or organisms in a controlled environment. It functions as a vessel-like
Mar 26, 2021 · The application of solid-state fermentation by different microorganisms (fungi, yeasts, bacteria) to produce several value-added products was analyzed, focusing on the exploitation of lactic acid bacteria as workhorses for the production of flavoring compounds. Keywords: waste, valorization, fermentation, lactic acid bacteria, flavor. Go to: 1.
Jan 22, 2020 · Fed-batch fermentation processes have been widely applied in many fermentation processes to produce various products and microbial lipids. The fed-batch cultivation process is superior to conventional batch cultivation and has been proven effective to increase the cell concentration and cellular lipid content in oleaginous microorganisms [16,17].
Nov 18, 2021 · Fossil fuels are a major contributor to climate change, and as the demand for energy production increases, alternative sources (e.g., renewables) are becoming more attractive. Biofuels such as bioethanol reduce reliance on fossil fuels and can be compatible with the existing fleet of internal combustion engines. Incorporation of biofuels can reduce internal combustion engine (ICE) fleet carbon
The abundance of organic solid waste throughout the world has become a common issue that needs complete management at every level. Also, the scarcity of fuel and the competition between food and substance as an alternative to a petroleum-based product has become a major problem that needs to be properly handled. An urge to find renewable substances for sustainable development results in a
Apr 10, 2018 · Lager fermenters are generally three to four times shorter in their diameter than the height and use an operation pressure of 1–1.5 bar. European fermentation tanks for lager beer commonly use shorter tanks with a diameter-to-height ratio of <2:1, which causes fermentation to equalize more completely than in horizontal vessels.
May 7, 2023 · Bioreactor Definition. A bioreactor is a type of fermentation vessel that is used for the production of various chemicals and biological reactions. It is a closed container with adequate arrangement for aeration, agitation, temperature and pH control, and drain or overflow vent to remove the waste biomass of cultured microorganisms along with their products.
Aug 1, 2023 · This review focuses on LA production from agricultural waste. Conventional fermentation approaches are discussed. Advanced fermentation techniques are also introduced, including cell immobilization, co-culture, simultaneous saccharification and co-fermentation.
Jul 7, 2023 · Food waste is categorized as organic solid waste, which has a negative impact on environmental sustainability. Food waste was simultaneously used for the feasible generation of mixed volatile fatty acids (VFAs) and bio-hydrogen by deploying dark fermentation. Original anaerobic digested sludge was prepared via the shock technique with 50 g/L glucose under thermophilic temperature (55 °C). The
