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).

Acidogenesis in Relation to In-Reactor Granule Yield
Water Science and Technology, 1992 A systematic study of in-reactor granule yield data was set up in the laboratory. Methanogenic granular sludge growth in fed batch shake flasks for different substrates appeared to decrease with the energy content of the substrate and required the presence of a mixing force.

Influence of substrate freshness on metabolite dynamics and methane emissions from pig slurry during laboratory incubation. [PDF]
J Environ QualAbstract Freeze/thaw pretreatment is commonly applied to animal slurry samples in laboratory studies, but its impact on organic matter transformation and methane (CH4) emissions remains uncertain. In this study, slurry incubations were performed at 20°C with three treatments differing in freshness of feces, urine, and inoculum.

Effect of Sulfate Reduction on the Acidogenesis of Sucrose.
Journal of Japan Society on Water Environment, 1995 Effects of COD/S ratio and hydraulic retention time (HRT) on the degradation of sucrose in acidogenic phase were evaluated by using anaerobic chemostat at 35°C. The COD/S ratio and HRT were changed in the range of 13 to 3,500 (control) and 2 to 10h, respectively.

Effect of Aso limonite on anaerobic digestion of waste sewage sludge
AMB Express, 2020 The effect of Aso volcanic limonite was explored in anaerobic digestion using waste sewage sludge (WSS). In this study, methane and hydrogen sulfide were remarkably inhibited when Aso limonite was mixed with WSS as well as a significant reduction of ...

Selected issues of anaerobic digestion based on the studies on hydrogen- and methane yielding bioreactors [PDF]
, 2019 Anaerobic digestion of organic matter results from the metabolic activity of many groups of microorganisms. Interactions between microorganisms during acidogenesis, acetogenesis and methanogenesis, source of inoculum, type of feedstock and operational ...

Optimizing volatile fatty acid production in partial acidogenesis of swine wastewater
, 2004 This research has been conducted based on the fact that acetic and butyric acids are favorable substrates for methanogens, and that a low level of propionic acid production during acidogenesis minimizes the inhibition effect on methanogenic growth.
