Spatial monitoring of hydrolysis in a plug-flow bioreactor: a support for flexible operation?
Bioresources and BioprocessingHydrolysis at changing hydraulic retention time, recirculation, bedding straw content in the feed, bioaugmentation and the impact of those changes on gradient formation in the liquid phase in plug-flow reactors (PFRs) was examined.

Waste to Bioplastic Conversion by the Moderate Halophilic Bacterium Halomonas Boliviensis
Chemical Engineering Transactions, 2016 The main purpose of this work was to evaluate the use of a waste stream for the production of polyhydroxyalkanoates (PHA). With the anaerobic acidogenesis process it is possible to treat and revaluate complex waste into a wide combination of volatile ...

Interdisciplinary Medicine, Volume 4, Issue 4, July 2026.A CRISPR/Cas12a‐powered dendritic DNA nanostructure is assembled to create confined enzymatic microdomains, enabling ultrasensitive detection. Integrated into a paper‐based origami biosensor, it allows equipment‐free on‐site quantification of acidogenic pathogens for the early diagnosis of dental caries.

CleanMat, Volume 3, Issue 2, Page 74-98, June 2026.Efficient conversion of organic waste to biogas depends on the coordinated optimization of feedstock composition, pretreatment, operational parameters, reactor design, and microbial community dynamics. This review highlights how these interacting factors improve methane yield and process stability, advancing anaerobic digestion as a practical pathway ...

Methane emissions from fresh dairy cattle and pig slurry
Journal of Environmental Quality, Volume 55, Issue 3, May/June 2026.Abstract During manure storage, methane (CH4) is produced by anaerobic decomposition of organic matter by methanogens. Frequent removal and further processing of manure from the barn can reduce CH4 emissions. However, little is known about how much CH4 is lost during the adaptation of methanogens to the changing environment from the gut to storage. The

Thermodynamics of anaerobic digestion: Mechanism of suppression on biogas production during acidogenesis [PDF]
, 2019 Anaerobic digestion process consists of several stages in which different type of microorganisms are involved. The current study reviews some possible reactions occurred in anaerobic digestion particularly in acidogenesis stage.

Mathematical model of anaerobic digestion in a chemostat: effects of syntrophy and inhibition
Journal of Biological Dynamics, 2013 Three of the four main stages of anaerobic digestion: acidogenesis, acetogenesis, and methanogenesis are described by a system of differential equations modelling the interaction of microbial populations in a chemostat.
