Maximization of volatile fatty acids production from alginate in acidogenesis
Bioresource Technology, 2013In this study, the response surface methodology (RSM) was applied to determine the optimum fermentative condition of alginate with the respect to the simultaneous effects of alginate concentration and initial pH to maximize the production of total volatile fatty acids (TVFAs) and alcohols.

Effect of xylitol and sorbitol on plaque acidogenesis.
Quintessence international (Berlin, Germany : 1985), 2009To evaluate the in vivo potential of xylitol to reduce plaque acidogenicity in comparison to sorbitol.After completing a questionnaire on general health, smoking, diet, and oral hygiene habits, 61 dentate adults refrained from oral hygiene for 3 days before the clinical baseline examination, which included decayed, missing, and filled teeth (DMFT ...

Anaerobic acidogenesis of primary sludge: The role of solids retention time
Biotechnology and Bioengineering, 1994AbstractThis research investigates the effect of solids retention time (SRT) on the acid‐phase anaerobic digestion of primary sludge. A series of experiments were conducted using two continuous‐flow 3‐L units with the following configuration: a completely mixed reactor (CMR) with clarifier and solids recycle and an upflow anaerobic sludge blanket (UASB)

Effects of Ammonia on Acidogenesis of Protein-Rich Organic Wastes
Environmental Engineering Science, 2008This study investigated the influence of ammonia on mesophilic acidogenesis of protein-rich organic waste, examined at initial ammonia concentration of 0–16 g-N L−1 at a neutral pH. VFA was dominant products from protein's acidogenesis, accounting for 80–90%, compared to lactic acid and alcohols.

Acidogenesis and Two‐Phase Codigestion of Fats, Oils, and Greases and Municipal Biosolids
Water Environment Research, 2013ABSTRACT: Acidogenic codigestion of fats, oils, and greases (FOG) was studied using suspended growth sludge digesters operated as batch fed reactors that were fed twice daily. The digesters were maintained at a 2‐day retention time and at 37 °C to mimic the acid phase of an acid‐gas digestion system. As FOG loading rates increased, volatile fatty acid (

Effect of Alkali Metal Cation on the Anaerobic Hydrolysis and Acidogenesis of Vegetable Waste
Environmental Technology, 2006Five batch testing scenarios were designed to evaluate the effects of alkali metal cations on anaerobic hydrolysis and acidogenesis. These scenarios were A (c=0 g l(-1)), B (cNa+=25 g l(-1)), C (cNa+=50 g l(-1)), D (cK+=25 g l(-1)), and E (cK+=50 g l(-1), pH 7.0).

Effect of heavy metals on acidogenesis in anaerobic digestion
Water Research, 1993The effects of chromium, cadmium, lead, copper, zinc and nickel on volatile fatty acid (VFA) production in anaerobic digestion were studied using serum bottle assays. Glucose acclimated seed sludge was used. The relative toxicity of heavy metals to production of acetic acid (HAc) and n-butyric acid (n-HBu) was Cu > Zn > Cr > Cd > Pb > Ni and Cu > Zn ...

Effect of cadmium and nickel on acidogenesis in anaerobic treatment
2020ÖZET Atıksu arıtımı su kaynaklarının kirlenmesini önlemek ve yeniden kullanımını sağlamak bakımından modern dünyanın önemli bir gereğidir. Anaerobik çürütme az enerji ve kaynak kullanması, metan gazı eldesine olanak vermesi ve az çamur meydana getirmesi nedenleriyle atıksu arıtma alanında birçok uygulama alam bulmuştur.
