Lifespan and bioactivity improvement of bacteriophages immobilized on carboxymethylcellulose - Cationic starch-coated paper for food packaging.

Bacteriophages (phages) have a great potential to target specifically foodborne bacterial pathogens, particularly in packaging materials. However, incorporating phages into packaging surfaces requires stabilizing their structure and maintaining their infectivity during the papermaking process. In this study, several coating formulations containing various ratios of carboxymethyl cellulose, cationic starch, and glycerol were applied to a base paper to assess phage stability.

Correlations and impact of anaerobic digestion operating parameters on the start-up duration: Database construction for robust start-up guidelines.

Anaerobic digestion (AD) has become a popular technique for organic waste management while offering economic and environmental advantages. As AD becomes increasingly prevalent worldwide, research efforts are primarily focused on optimizing its processes. During the operation of AD systems, the occurrence of unstable events is inevitable.

Evaluating the impact of substrate addition for anaerobic co-digestion on biogas production and digestate quality: The case of deinking sludge.

To reduce greenhouse gas emissions from organic waste, anaerobic digestion has created new opportunities for energy and nutrient recovery from these wastes. However, the use of certain organic wastes in anaerobic digestion is limited due to their atypical physicochemical characteristics (e.g.

A simple mass balance tool to predict carbon and nitrogen fluxes in anaerobic digestion systems.

The increase in anaerobic digestion systems has profoundly affected the waste management of territories, particularly for agricultural systems. Changes in cultural practices and imports of organic waste modify the carbon (C) and nitrogen (N) fluxes on territories where anaerobic digestion is implemented. Successful anaerobic digestion can increase the economic and ecological efficiency of the waste management system.

Use of fermentation processes for improving the dissolution of phosphorus and its recovery from waste activated sludge.

Recycling phosphorus from waste activated sludge has attracted a lot of interest to tackle the problem of phosphorus stocks depletion and the increase in food demand. In this study, the use of fermentation processes was investigated to enhance phosphorus dissolution from waste activated sludge to improve its recycling. Two fermentation processes, bioacidification and dark fermentation, were used on two different sludges fermented with wheat starch syrup in continuous operating conditions.
