Dec 18, 2023 · Definition and Function of a Fermenter. A fermenter can be defined as a specialized vessel or apparatus designed to provide an optimal environment for the fermentation process. It is a controlled environment where microorganisms transform organic substances into more desirable compounds through biochemical reactions.
A Fermentor is a device used to accomplish the fermentation process by using microorganisms, and for this reason, it is also called “ Biofermentor or Bioreactor “. It is equipped with all the elements that are necessary to carry out the commercial production of substances like antibiotics, enzymes, beverages etc. in many industries.
The fermenter consisted of a large cylindrical tank with air introduced at the base via network of perforated pipes. In later modifications, mechanical impellers were used to increase the rate of mixing and to break up and disperse the air bubbles (Fig. 20.1). This process led to the compressed air requirements.
Nov 1, 2023 · In all phases, the reactor was operated at room temperature (22 °C), while the fermentation cycle was fixed at 14 days which is the typical fermentation time for LBRs operated on food waste [20]. High hydrolysis and acidogenic activities have been reported at near-neutral pH conditions [11], [21]. Therefore, the pH of the reactors was
Oct 1, 2012 · The general idea to use food waste as a co-substrate for treating materials, whose biodegradability need improvement, can be confirmed by our examinations. Although in this study food waste (consisting of different waste kinds, see 2.1 Substrate) as single substrate was anaerobically digested, the results allow the mentioned assumption.
Oct 1, 2001 · Feedstock for this experiment was food waste collected from a dining hall. The distribution of grains, vegetables and meats in the waste was 40.5, 44.2 and 15.3%, respectively. The leaching beds were operated in a rotation mode with a two-day interval between degradation stages as shown in Table 1. Acidified products in leachate from four
The first pilot fermenter was erected in India at Hindustan Antibiotic Ltd., Pimpri, Pune in the year 1950. Basic criteria of the fermenter . The vessel should be capable of being operated aseptically for a number of days and should be reliable in long-term operation and meet the requirements of containment regulations.

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.
Jul 1, 2013 · The H 2 fermentation was conducted as described in our previous work (Kim et al., 2011). In detail, prior to addition, food waste and sewage sludge were boiled at 90 °C for 20 min to prohibit methanogenic H 2-consuming activity. In the fermenter, first, food waste corresponding to 30 g Carbo. COD/L (g/L as carbohydrate COD) was placed in the
Mar 1, 2007 · Ueno et al. [57] operated a two-stage fermentation process producing hydrogen from organic waste where Thermoanaerobacterium and related organisms produced hydrogen at the yield of 2.4 mol/mol
Ethanol Fermentation. João Nunes de Vasconcelos, in Sugarcane, 2015. 15.11.2 Foam Presentation. When ethanol fermentation occurs within normality, with good performance, the bubbles formed are regular and with a certain glow, keeping the same pattern throughout the surface of the fermentation environment, and are easily broken by the pressure exerted by the carbon dioxide released during
Mar 8, 2022 · Abstract. A fermenter (bioreactor) is a closed vessel with sufficient aeration, agitation, temperature, and pH regulation arrangements and a drain or overflow vent to extract the waste biomass along with its products from cultured microorganisms. The fermenter is intended for the production of biological products.
Aug 11, 2020 · Traditionally, fermentation has been practiced to preserve any available resources into the most delicious foods that can be enjoyed throughout the changing seasons. A few familiar examples include curing meats, olives, cheeses, and summer winemaking with seasonal berries and grapes.
Aug 25, 2023 · The hybrid approach of fungal solid-state fermentation with dark fermentation with Biohydrogen bacterium R3 showed 52.4 mL H 2 /g food waste (294.47 mL H 2 /VS added) (Han et al., 2016). Comparatively, their previous study reported 39.14 mL H 2 /g food waste of 219.91 mL H 2 /VS added from 4 % food waste mass ratio.
