Effect of HRT on Mesophilic Acidogenesis of Dairy Wastewater
Journal of Environmental Engineering, 2000Effect of hydraulic retention time (HRT) on the acidogenesis of dairy wastewater was studied using an upflow reactor at pH 5.5, 37°C, and six HRTs ranging from 4 to 24 h. Results showed that the degree of acidification increased rapidly with HRT from 28.2% at 4 h to 54.1% at 12 h; further increase of HRT to 16 and 24 h only increased acidification ...

Acidogenesis of cellulosic hydrolysates for new generation biofuels
Biomass and Bioenergy, 2016Abstract This article presents a comprehensive review on hydrolysis and acidogenesis of lignocellulosic waste biomass and makes clear new perspectives in biofuel research. Specifically, the acidogenesis of lignocellulosics and liquid effluent have been discussed extensively with potential goal the production of a new generation biofuel.

Characterisation of high-rate anaerobic acidogenesis
2020Detailed in-depth knowledge of acidogenesis is important for the development of robust and optimised anaerobic digestion processes, and also to selectively produce certain acids or other by-products such as hydrogen during the conversions. Although the complete anaerobic digestion process has been studied for a long time, the detailed understanding of ...

Acidogenesis in relation to fluoride resistance of Streptococcus mutans
Oral Microbiology and Immunology, 1991The velocity of acid production (Vap) of Streptococcus mutans C180‐2 and of 2 fluoride‐resistant mutant strains S. mutans C180‐2FR and S. mutans C180‐2MFR was examined in vitro at pH values between 7.0 and 4.5. The Vap of the fluoride‐resistant mutants was lower than the Vap of the parent strain at pH ≥6.0.

Anaerobic fermentation of cattle manure: Modeling of hydrolysis and acidogenesis
Water Research, 2007A mathematical model for the hydrolysis and acidogenesis reactions in anaerobic digestion of cattle manure is presented. This model is based on the premise that particulate hydrolysable fraction of cattle manure is composed of cellulose and hemicellulose that are hydrolyzed at different rates according to a surface-limiting reaction; and, that the ...

Giornale di stomatologia e di ortognatodonzia, 1989
The Authors consider the inhibition of acidogenesis in the dental plaque by topical application of fluoride. After an examination of the actions of fluoride on the bacterial component of dental plaque, the Authors come to the conclusion that inhibition of acidogenesis is one of the possible anticaries mechanism of topical fluoride.

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.

Comparative Plaque Acidogenesis of Caries-resistant vs. Caries-susceptible Adults
Journal of Dental Research, 1982The authors conducted a comparative study of plaque acids in three-day fasting or resting plaque samples from ten pairs of caries-resistant (CR) and caries-susceptible (CS) subjects chewing a sucrose gum for a period of 45 min. The study disclosed two important differences: 1) The amount and rate of production of lactic acid were lower in the CR group,
