Inhibition by chromium and cadmium of anaerobic acidogenesis
Water Science and Technology, 2001 The effects of chromium (III) and cadmium on the anaerobic acidogenesis of a simulated dairy waste were examined using serum vials. At Cd dosages less than 20 mg/l, the acidogenesis process was enhanced by the dosage, resulting in a higher degree of acidification, protein conversion, and hydrogen production than the control. At dosages over 20-mg/l, Cd

Effect of rapid temperature change and HRT on anaerobic acidogenesis
Water Science and Technology, 1997 The effects of the rapid change in temperature and HRT on the characteristics of substrate degradation and bacterial population levels in anaerobic acidogenesis were investigated by using the laboratory scale anaerobic reactor. The degradation efficiency of substrate in acidogenesis was significantly affected by the rapid drop in temperature ...

Simultaneous Assessment of Acidogenesis-Mitigation and Specific Bacterial Growth-Inhibition by Dentifrices. [PDF]
PLoS ONE, 2016 Dentifrices can augment oral hygiene by inactivating bacteria and at sub-lethal concentrations may affect bacterial metabolism, potentially inhibiting acidogenesis, the main cause of caries.

Acidogenesis of dairy wastewater at various pH levels
Water Science and Technology, 2002 Continuous experiments were conducted to study the influence of pH in the range 4.0–6.5 on the acidification of dairy wastewater at 37°C with 12 hours of hydraulic retention in an upflow reactor. Results showed that degradation of dairy pollutants increased with pH from pH 4.0 to 5.5. At pH 5.5, 95% of carbohydrate, 82% of protein and 41% of lipid were

Synergies revealed: RNA-seq study of C. acetobutylicum and C. carboxidivorans co-cultured in the presence of conductive materials [PDF]
Microbiology SpectrumCo-cultures can improve substrate utilization and product yields, yet the dynamics between species remain highly variable and poorly understood. In this study, we investigated the metabolic and transcriptional interplay between Clostridium acetobutylicum

In situ buffering and enzymatic regulation of acidogenesis in two-stage anaerobic digestion of composite vegetable waste [PDF]
Scientific ReportsPeels of vegetable waste (VW), rich in cellulose, lignin, and hemicellulose, can impede hydrolysis due to reduced enzymatic accessibility and activity. This research comparatively evaluated the effects of composite vegetable waste (CVW) comprising of 2:3

Isolation of Kombucha Microorganisms for Application in Perilla Beverage Fermentation. [PDF]
Food Sci NutrFive commercial kombucha samples from Vietnam were screened, yielding 37 isolates (22 AAB, 6 LAB, 9 yeasts). Three representative strains—Komagataeibacter saccharivorans, Levilactobacillus brevis, and Wickerhamomyces anomalus—were identified and combined into a defined starter consortium (yeast: AAB: LAB = 2:2:1).
