2023/11/1/ · 1. Introduction. Solid-state fermentation (SSF) is a commonly used fermentation technology for growing microorganisms on solid substrates without free water flow [1], [2], [3].The solid substrate contains enough moisture to support microbial activities without adding water [2, 4, 5].The solid substrate can be the source of nutrients for
2024/5/1/ · It is imperative to note that lactic acid-type fermentation liquid (LAFL) markedly differs from VFA-rich fermentation liquid. During the fermentation process of food waste, lactic acid is preferentially produced during glycolysis due to its lower Gibbs free energy requirement compared to VFA (Holtzapple et al., 2022, Zhou et al., 2018).
2023/10/6/ · Plus, all of its stainless steel parts are dishwasher-safe, making it one of the easiest-to-clean airlock kits we've come across. Includes: 1 (1L) Le Parfait jar; 1 stainless steel fermentation
2024/3/1/ · Organic waste contains a large amount of matter containing carbon, so it is feasible to use it as substrate or electron donor to produce medium chain fatty acids, such as in a fermentation broth of organic waste such as sludge, food waste, fruit and vegetable waste, etc (Reddy et al., 2020; Wang et al., 2020a, Wang et al., 2020b, Wang et al
2023/10/12/ · Lactic acid is a versatile chemical with a wide range of industrial applications, including food additives as well as the production of biodegradable plastics, pharmaceuticals and cosmetics. LA can be produced through carbohydrate fermentation using various microorganisms, including lactic acid bacteria (LAB). However, the high
The main problem is that the versatile composition of organic wastes leads to a combination of fermentation products in various amounts. Therefore the technological challenges are: 1. Development of a continuous bioreactor system for complete waste transformation towards a major fermentation product 2.
However, this method exhibits several disadvantages, including low efficiency and serious waste generation, which makes it difficult to meet the current market demand. With the rapid development of synthetic biology and the deepening of high-density fermentation technology, the collagen preparation by biosynthesis strategy emerges as the times

2022/12/12/ · Solid-state fermentation (SSF) is part of the pathway to consolidate waste as a relevant alternative for the valorization of organic waste. The objective of SSF is to produce one or several bioproducts of added value from solid substrates. Solid-state fermentation can use a wide variety of organic waste as substrates thus, it is an
2020/1/1/ · Industrial fermentation is a chemical engineering term used to describe the processes that utilize a chemical change induced by a living organism or enzyme, in particular bacteria, yeasts, molds, or fungi, that produces a specific product [1].Although in the biochemical context the word “fermentation” describes the anaerobic metabolic
2023/9/1/ · They offer versatility in brewing and can handle both primary and secondary fermentation. Primary Use: Versatile; suitable for various fermentation processes; Price Range: $5,000 – $50,000 based on features and size. 4. Flat-Bottomed Tanks. Description: These are the traditional fermenting tanks with a flat base. They are used across
2023/2/22/ · The fed-batch cultivation is in many ways a benchmark for fermentation processes, and it has been an attractive choice for the biotechnological production of various products in the past decades. The majority of biopharmaceuticals that are presently undergoing clinical trials or are available on the market are manufactured through fed
2022/11/1/ · The remaining solids were centrifuged from hydrolysis mixture with 10000 rpm for 15 min. The FW hydrolysate was filtered and pumped to fermenters for ethanol fermentation by Saccharomyces cerevisiae. The ethanol fermentation was operated at the conditions of 30℃ and 400 rpm agitation speed (Chen et al., 2021). In order to reduce the
2022/9/12/ · During the anaerobic fermentation process, the organic loading rate is defined as the quantity of the material fed to the reactor per day per unit operating volume. Municipal waste fermentation plants generally operate at loading rates of 1.2–12.0 kg VS or 2.2–33.7 kg COD per cubic meter per day [58, 76,77,78]. During the entire anaerobic
2018/1/1/ · 3. Classification of Bioreactors for Solid-State Fermentation. Based on the scale of operation, the SSF bioreactors can be categorized into two types: (1) laboratory scale and (2) pilot and industrial scale. The first class of bioreactors comprises many designs with less sophistication while the latter class is mainly used at industrial level
