Product Introduction

Biodegradation of wool waste and keratinase production in

May 3, 2013 · With the glucose fed-batch procedure in 30-L fermenter, keratinase production was significantly improved up to 117.7% (1728U/ml) as compared with initial data (793.8U/ml) in a 3-L fermenter and

Volatile fatty acids production from kitchen waste slurry

May 1, 2024 · High-quality VFAs was efficiently produced from kitchen waste slurry by AnMBR. •. Alkaline fermentation suppressed methanogenesis and acquired a high VFAs yield. •. Microbial community was reshaped to promote VFAs production at alkaline condition. •. Membrane fouling could be alleviated by chemical cleaning and sludge discharge. Abstract.

An overview of fermentation in the food industry - looking

Nov 28, 2023 · Due to its low cost, high productivity, and simplicity, submerged fermentation is more commonly used in industrial-scale fermentation. Food waste is considered an excellent input for microbial fermentation due to its abundance of phenolics, proteins, fatty acids, minerals, and several bioactive ingredients.

Current perspectives on acidogenic fermentation to produce

Feb 13, 2021 · The current route for VFA production is petrochemical based. VFAs can be biologically produced using organic wastes as substrate, therefore directly contributing to a sustainable economy. This process is commonly known as acidogenic fermentation (AF).

Production Fermenter - an overview | ScienceDirect Topics

The scale of manufacturing, often designated by the scale of the production fermenter or bioreactor, has a major impact on the cost of manufacturing. Generally, manufacturing labor requirements increase more slowly than volume increases. For example, a 2000 L bioreactor does not require ten times as many operators to run as a 200 L bioreactor does.

Bioreactor- Definition, Design, Principle, Parts, Types

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.

Enhanced lactic acid production from food waste in dark

Jun 11, 2020 · This study investigated the effects of pH, total solids (TS) content, and enzymatic pretreatment on lactic acid (LA) production from food waste with indigenous microbiota. A multilevel factorial design was applied to all the essential factors for making LA production the most efficient and productive. The experimental data revealed that all the tested factors had a significant effect on the LA

Lactic acid-based fermentative hydrogen production from

Although the observed yield is lower than the standard conditions for dark fermentative H 2 production, lactate-based H 2 production offers an alternative pathway for organic waste valorization. To maintain optimal pH for H 2 production, the pH of the R2 group was adjusted to 6.5 during the second stage of operation.

Fermenter Design | SpringerLink

Mar 8, 2022 · 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. The fermenter’s design and mode of

Medium chain Fatty acids production from Food Waste via

Apr 1, 2024 · To restore the anaerobic environment, the bioreactors were flushed with pure N 2 before sealing, except the reactors for Batch#3, which were flushed with pure H 2.At regular time intervals (t = 0 h; 24 h; 48 h; 72 h; 144 h; 192 h), the reactors were sampled to perform the chemical characterization of the fermentation broth.

Role of Microbial Fermentation in the Bio-Production of Food

Jan 31, 2024 · Flavour is a key driver of consumer preferences and acceptability of foods, and the food industry has made food aroma compounds a crucial area of research. At present, about 80% of food aroma compounds are produced by chemical synthesis; however, alternative production approaches have been explored to meet consumers’ demand for “clean label” food products and “natural” aromas. Bio

Foods | Free Full-Text | Fermentation of Agri-Food Waste: A

Mar 26, 2021 · In this view, FW is considered as a byproduct and resource, and several studies about waste and byproduct valorization have been conducted in recent decades [ 4, 5, 6 ]. FW is defined as any part of food that is discarded, regardless of its potential content of compounds retaining a high value [ 7 ].

Dark fermentative hydrogen production: Potential of food

Aug 25, 2023 · Co-fermentation of municipal food waste with kitchen wastewater having high value of COD (260–1380 mg/L) and total nitrogen (40–74 mg/L) along with high substrate degradation ability of anaerobic microorganisms was improved biohydrogen production (Tawfik et al., 2015). The aim of the present review is to provide an updated overview of

Advanced Fermentation Techniques for Lactic Acid Production

Aug 17, 2023 · Lactic acid plays an important role in industrial applications ranging from the food industry to life sciences. The growing demand for lactic acid creates an urgent need to find economical and sustainable substrates for lactic acid production. Agricultural waste is rich in nutrients needed for microbial growth. Fermentative production of lactic acid from non-food-competing agricultural waste

Co-fermentation of titanium-flocculated-sludge with food

Mar 1, 2024 · For a more practical interpretation, a semicontinuous co-fermentation experiment was conducted for 48 days using the dry weight ratio of Ti-loaded sludge to food waste of 3:1 as the standard. One-fourth of the fermentation substrate was replaced every two days, maintaining an SRT and HRT of 8 days.
