Biochemical and structural characterization of a tail‐spike protein with depolymerase activity identified in a marine podovirus

Acta Crystallographica Section D, Volume 82, Issue 7, Page 785-799, July 2026.
The marine tail‐spike protein Dpo31 degrades the exopolysaccharide of its host and has structural features similar to those of other members of this protein class, despite similarity not being detected at the sequence level.Marine phages are, through the infection of their bacterial hosts, key regulators of microbiome and carbon fluxes in the ocean ...

Wheat Bran‐Derived Carbohydrates as Functional Food Ingredients: Extraction and Evaluation of Prebiotic Potential

Journal of Food Science, Volume 91, Issue 7, July 2026.
ABSTRACT Wheat bran (WB) is a rich source of non‐starch polysaccharides, particularly arabinoxylans, which can be valorized into functional food ingredients with potential prebiotic properties. This study investigated the extraction of carbohydrates from WB using ultrasonic and hydrothermal treatments and evaluated their technological and functional ...

Characterization of Air and Ozone Micro‐Nano Bubbles and Their Impacts on Physicochemical Attributes, Total Phenolic Content, and Natural Microbial Load of Fresh “Fan Retief” Guava During Storage

Journal of Food Science, Volume 91, Issue 7, July 2026.
ABSTRACT Chlorine‐based water treatment for fresh produce has diverse limitations including the production of disinfectant‐by‐product residue. Thus, this study characterized and investigated the impact of micro‐nano bubble (MNB) water (air and ozone (O3)) on the quality attributes of guava fruit during storage.
