A chloramphenicol resistant strain of S. typhi which caused a very large epidemic of typhoid fever in Mexico in 1972-73 survived in opened bottles of one carbonated drink with a pH of 4.6 for two weeks and in another such drink with a pH of 5.1 for six months. Bottled beverages are potential sources of large outbreaks of enteric disease, and deserve the same type of standards sand monitoring as comparable fluids such as milk.

The European Union aims for climate neutrality by 2050 and has proposed the Packaging and Packing Waste Regulation (PPWR) to promote a circular economy, focusing on reducing packaging waste. In this context, a comprehensive sustainability assessment for liquid dairy product packaging, including beverage cartons, bottles and to-go cups, in the DACH region (Germany, Austria and Switzerland) was conducted. The aim was to consider various ecological aspects of environmental impacts and circularity.

Polyethylene terephthalate (PET) is widely used across various industries owing to its versatility and favorable properties, including application in beverage bottles, food containers, textile fibers, engineering resins, films, and sheets. However, polymer materials are susceptible to degradation from factors such as light, oxygen, and heat. Therefore, it is crucial to understand the structural changes that occur during degradation and the extent of these changes.

Fraud in alcoholic beverages through counterfeiting and adulteration is rising, significantly impacting companies economically. This study aimed to develop a method using near-infrared (NIR) spectroscopy (1596-2396 nm) through the bottle, along with machine learning (ML) modeling for beer authentication, quality traits, and control assessment. For this study, 25 commercial beers from different brands, styles, and three types of fermentation were used.

Department of Biology, University of Padova, 35131 Padova, Italy. Electronic address:
The fermentation process in alcoholic beverage production converts sugars into ethanol and CO, releasing significant amounts of greenhouse gases. Here, Cupriavidus necator DSM 545 was grown autotrophically using gas derived from alcoholic fermentation, using a fed-batch bottle system. Nutrient starvation was applied to induce intracellular accumulation of poly(3-hydroxybutyrate) (PHB), a bioplastic polymer, for bioconversion of CO-rich waste gas into PHB.
