Enhanced Biomethane Recovery From Source‐Separated Cow Urine via Co‐Digestion With Waste Paper

open access: yesGCB Bioenergy, Volume 18, Issue 7, July 2026.
This study outlines the experimental process where cow urine, collected from a dairy barn equipped with a source‐separating manure system, and waste paper are loaded into bioreactors (CU0–CU50) at varying ratios to analyze the biogas yield. The analytical results highlight that this collection system significantly enhances biogas and biomethane ...

Mathematical Modelling of Anaerobic Mesophilic Sewage Sludge Treatment

open access: yes, 1993
A mathematical model was developed to describe the dynamic behaviour of the anaerobic mesophilic digestion. Special emphasis was given to the acetate degradation kinetics, as the step that determines the stability of anaerobic digestion.

Density discriminates between thermophilic and mesophilic proteins

open access: yes, 2017
Despite an intense interest and a remarkable number of studies on the subject, the relationships between thermostability and (primary, secondary and tertiary) structure of proteins are still not fully understood.

Metal‐Dependent Effects and Crowding Robustness of Pseudomonas fluorescens Esterase I

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Pseudomonas fluorescens esterase I retains catalytic activity in metal‐rich and crowded environments, despite metal‐specific inhibitory effects. These findings highlight its robustness for biocatalytic applications in complex environments. Industrial biocatalysts are strongly influenced by their physicochemical environment, yet systematic studies on ...

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2842-2861, June 2026.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Comparative performance of mesophilic and thermophilic acidogenic upflow reactors

open access: yes, 2002
Two anaerobic acidogenic reactors, one mesophilic (37°C) and one thermophilic (55°C), were operated with a synthetic wastewater at a series of organic loading rates (OLRs).

Effect of Chitosan, Aloe vera Gel and Coconut Oil Edible Coatings on Postharvest Quality and Shelf Life of Strawberry (Fragaria × ananassa Duch) Under Ambient Storage

open access: yesFood Science &Nutrition, Volume 14, Issue 6, June 2026.
Postharvest application of eco‐friendly edible coatings consisting of chitosan solution (CH), Aloe vera gel (AVG), and coconut oil (CO) on strawberry fruit under ambient conditions. Six distinct formulations (CH, AVG, CO, CH + AVG, CH + CO, and AVG + CO) along with a distilled water (control) were analyzed.
