Rice University via OpenStax CNX. High-performance liquid chromatography (HPLC) is a technique in analytical chemistry used to separate the components in a mixture, and to identify and quantify each component. It was initially discovered as an analytical technique in the early twentieth century and was first used to separate colored compounds.
2018/3/1/ · In this study, the performance of DCMD in treating fermentation wastewater with high organic concentrations was investigated for the first time. The results showed that after the 12 hr DCMD process, the volume of the feed wastewater, COD, TOC and protein in the feed fermentation wastewater were concentrated by 3.7, 3.5, 3.4 and 3.5 times
2015/1/1/ · Avocado fermented juice was prepared. The organic acids: malic acid, citric acid and tartaric acid in this juice were determined by reversed phase high performance liquid chromatography.
2023/9/1/ · During fed-batch fermentation, OD 600 and CDW were used to evaluate yeast growth. Supplementary Figure 1 shows the strong correlation between these two parameters (R 2 = 0.995). Glucose and ethanol concentrations were determined by high-performance liquid chromatography (HPLC) and gas chromatography (GC), respectively .
2024/2/25/ · The pH conditions can determine the fermentation performance, and the pH range of 4.0–5.0 was suitable for harvesting small molecules of organic acids and alcohols . At the start of the experiments, each reactor was loaded with 1080 mL of prepared FW as the substrate and 120 mL of biogas slurry as the inoculum.
2015/8/1/ · A high performance liquid chromatographic method was established for the determi-nation of metabolites (sugars, organic acids and alcohols) in microbial consortium fermenta-tion broth from cellulose.
2022/4/29/ · Volatile fatty acids (VFAs) are the important intermediates indicating the stability and performance of fermentation process. This study developed the spectrophotometric method for determining high-range VFA concentration in mixed-acid fermentation samples. The performance was compared with the gas chromatography
2022/12/16/ · Large amounts of secondary pollutants are released during traditional composting, and rapid fermentation is desirable for the stabilization of food wastes. Food wastes were mixed with rice husk, placed in a bioreactor, and stirred continuously to achieve high-temperature fermentation for 14 h. The transformations of the mixtures were
2017/4/1/ · A 7 L commercial fermenter (Major Science, USA) with 3 L working volume was operated in semi-continuous mode for 128 days at 55 °C (Fig. 1).The overhead mixer was controlled at 100 rpm throughout the entire fermentation period. 0.5 L of fermented sludge was withdrawn and replaced with the 0.5 L of feed sludge daily resulting in a SRT of 6 days.
2023/9/1/ · Given its high organic matter content and easy biodegradability, kitchen wastewater is an ideal substrate for anaerobic fermentation (Ren et al., Novel strategy to stimulate the food wastes anaerobic fermentation performance by eggshell wastes conditioning and the underlying mechanisms. Chem. Eng. J., 398 (2020), Article 125560.
2024/6/1/ · However, commercial organic matters used in practical engineering would increase costs. Anaerobic sludge fermentation was a promising means of resource utilization of waste activated sludge (WAS), and the sludge fermentation liquor (SFL) was rich in a variety of volatile fatty acids (VFAs) (Liu et al., 2016).
2024/5/28/ · In this report, based on spectrum coupling, thermal effect, and multiphase flow properties of hydrogen production, continuous pilot-scale biohydrogen production
2024/2/1/ · Effect of THP time on VFAs production of acidogenic fermentation. The performance of sludge acidogenic fermentation in response to different THP times was evaluated by the production and composition of VFAs. Fig. 1 (A) exhibits the VFAs accumulation was significantly enhanced with the longer THP time (20 and 30 min) (p < 0.05).
