Listeria monocytogenes Response to Anaerobic Environments

2020/3/12/ · Abstract. Listeria monocytogenes is a Gram-positive facultative anaerobic bacterium that is responsible for the disease, listeriosis. It is particularly lethal in pregnant women, the fetus, the elderly and the immunocompromised. The pathogen survives and replicates over a wide range of temperatures (4 to 42 °C), pH, salt and oxygen

Dry fermenters for biogas production - ScienceDirect

2020/1/1/ · SSAF or dry fermentation (DF) is defined as a fermentation process in which digestion occurs in the absence of water while the substrate possesses enough moisture content to support the growth as well as the metabolism of microbes [11].The usage of SSAF has been increasing since 2005 as the technique gives both economic

Cellulase–lactic acid bacteria synergy action regulates silage

2023/8/4/ · Background Feed shortage is an important factor limiting livestock production in the world. To effectively utilize natural woody plant resources, we used wilting and microbial additives to prepare an anaerobic fermentation feed of mulberry, and used PacBio single-molecule real-time (SMRT) sequencing technology to analyse the

Applying machine learning to anaerobic fermentation of waste

2024/3/15/ · Anaerobic fermentation is an effective method to harvest volatile fatty acids (VFAs) from waste activated sludge (WAS). Accurately predicting and optimizing VFAs production is crucial for anaerobic fermentation engineering. In this study, we developed machine learning models using two innovative strategies to precisely predict the daily

Fermentative Foods: Microbiology, Biochemistry, Potential

2020/12/31/ · (Β) Controlled fermentation with starter cultures: A fermentation that starts with the addition of a suitable inoculation with a large population of the desired fermentation microorganisms, necessary when the raw material is pasteurized (e.g., pasteurized milk) or when it is difficult for the desired fermentation microorganisms to

Metagenomic insights into improving mechanisms of Fe0

2022/10/1/ · Anaerobic fermentation has been verified to be an ideal and environmentally (Beijing, China), which was manually peeled from fresh potatoes. Moisture content, volatile solids (VS) content, carbohydrate content, carbon content, nitrogen content, and C/N ratio of the PPW were 80.1 %, 859.3 mg/g-dry solids, 665.7

Target and Enhance Ethanol and Butyrate Production from Anaerobic

2022/8/3/ · Compared to the FVW natural fermentation, the profit that comes from product revenue under the regulated strategy, the initial pH 4.0 and controlled pH 6.0, was considerable. The profits under pH 4.0 and pH 6.0 regulation condition were 240.75 and 435.97 RMB per ton FVW, respectively.

The anaerobic fermentation of food waste: a comparison of two

2012/10/1/ · The primary aim of this project is to explore the method of anaerobic fermentation for the efficient utilization of the waste generated by the food industry. (70 °C for a minimum retention time of 1 h), which is regulated by law and statutory for the contained substrate components. For the laboratory experiments, the crushed and

Chapter 8 - Anaerobic fermentation - Cambridge University Press

4 天之前 · The catalase and superoxide dismutase genes are transcriptionally up-regulated upon oxidative stress in the strictly anaerobic archaeon Methanosarcina barkeri. Microbiology 152 , 1671 – 1677 . CrossRef Google Scholar PubMed

Solar energy application and its effect on - ScienceDirect

2022/12/1/ · The anaerobic fermenter made of polymethylmethacrylate (PMMA) was a double-layer water bath container with the available volume of 8 L. The outermost layer was the water bath heating layer. The motor (51K40RGN-C) on the top of the container was set to mix for 2 min every 30 min with a speed of 80 r/min.

Modeling of industrial-scale anaerobic solid-state fermentation for

2020/8/15/ · Traditional solid-state fermentation processes can give fluctuating product quality and quantity due to difficulties in control and scale up. This paper describes an engineering study of an industrial-scale anaerobic solid-state fermentation process for Chinese liquor (Baijiu) production, aimed at better understanding of the traditional

A critical review on dry anaerobic digestion of organic waste

2023/4/1/ · 1. Introduction. Nowadays, the rapid consumption of fossil fuels has brought about severe energy crisis and environmental issues (e.g., climate change), which has hampered global progress towards the goals of economic, social, and cultural sustainability [1].An increasing consensus now views exploiting renewable energy to gradually replace
