2022/2/1/ · VFAs from fermented food waste, when used for lipid production by Cryptococcus, curvatus, resulted in a low lipid content at 13.8%, which might be due to the presence of the low carbon-to-nitrogen ratio (3.2:1), implying the importance of reducing nitrogen-containing compounds in the fermented waste if the lipid content is to be

2021/6/5/ · Well-designed and multidisciplinary research on the ED-BPM processes optimized for the recovery of organic acids directly from fermentation broth will certainly result in competitive industrial , with low energy consumption, a stable long-term

2024/5/28/ · Biological approaches include biophotolysis (direct and indirect), electrochemical systems (microbial electrolysis cells), and biological fermentation (dark

2024/2/20/ · Furthermore, in practice, the content of alcohols and acids is not solely determined by the components of food waste. For instance, Feng et al. (2018) found that the primary component in the food waste fermentation broth is lactic acid when the pH ranges from 3.2 to 4.5. However, when the pH is between 4.7 and 6.0, the fermentation process

2018/4/29/ · It should be pointed out that the acute toxicity of the food waste fermentation wastewater was very low, although it fluctuated during the treatment system. The toxic unit of raw wastewater was 5.47 TU, which is comparable with the toxicity of domestic sewages reported in previous research (Ma et al. 2011; Moraes et al. 2004).

2023/12/4/ · The ambition of LOW-Methane is to deliver at least 1 million metric tons of annual waste sector methane reductions well before 2030 working with 40 subnational jurisdictions and their national government counterparts, and to unlock over $10 billion in public and private investment. Reducing methane emissions from the waste sector is

2020/12/8/ · These bacteria utilizes the Wood–Ljungdahl pathway for fermentation to take place. Syngas fermentation of waste biomass has led to the development of biofuels rich in energy and valuable chemicals. Other than high gas-liquid mass transfer rates, process scale-up, low maintenance, and low operating costs are a few more key

2024/3/1/ · 1. Introduction. Potato is one of the four major food crops in the world, and its processing can produce about 15–40 % potato waste rich in nutrients such as dietary fiber, pectin, proteins, and starch [1].The global annual amount of potato waste exceeds 50 million tons based on potato yield [2].Potato waste is a rich biomass with great potential

2011/5/1/ · Lactic acid bacterial fermentation, which can, to a considerable extent, replace the expensive and non-environmentally friendly chemical processes, has been reported for shrimp waste demineralization [1], [12], [18]. During fermentation, lactic acid production creates a low pH condition.

2021/10/1/ · During food waste fermentation, the addition of biogas slurry promoted the production of lactic acid because it increased the pH values, maintained low OPR, prompted microbial diversity, and enriched functional microorganisms. A proper dose of industrial biogas slurry can increase the lactic acid yield to 0.42 g/g VS added. This result provides

2024/1/31/ · Highly efficient downstream processes. The team focused on two options for initial recovery of isopropanol and acetone: vacuum distillation and pass-through distillation. "Vacuum distillation was

Dry Fermentation of organic waste and manure. Dry fermentation (SSAD) in a biogas plant involves the fermentation of organic feedstocks to produce biogas under anaerobic conditions (without atmospheric oxygen). The solid fermentation plant consists of drivable, gas-tight, and acid-resistant concrete fermenter boxes, which are filled and emptied

2020/4/1/ · Now more than 90% of lactic acid production depends on pure culture fermentation, and mixed culture fermentation with lower maintenance and sterilisation costs has become a research hotspot in

2022/4/10/ · The addition of external carbon source for nitrogen removal from wastewater is an essential step in wastewater treatment. In this study, various external carbon sources from the fermentation of primary sludge (PS), thickened waste activated sludge (TWAS), food waste (FW), bakery processing & kitchen waste (BP + KW), fat, oil,

2024/4/1/ · Microbial fermentation, a method commonly utilized in the industry to produce LA, accounts for approximately 90% of LA production. This is largely due to its low production cost, high optical purity, and wide range of substrates (Agrawal and Kumar, 2023). In industrial LA processes, it is generally produced mainly based on starch or sugars.
