Trehalose and Glycogen Dynamics in Galleria mellonella Under Stress: Tissue‐Specific Insights

Entomological Research, Volume 56, Issue 7, July 2026.
ABSTRACT Insects employ flexible metabolic strategies to cope with acute environmental stress. This study investigates how different stressors, including physical, mechanical, and thermal, influence carbohydrate metabolism in Galleria mellonella larvae.

Purification and properties of trehalase(s) from Neurospora

, 1963
Trehalase has been obtained in crystalline form from the mycelium of Neurospora crassa. During elution from the first pass through a DEAE-cellulose column, two peaks with trehalase activity were obtained.

The activity of saccharolytic enzymes in Collembola is associated with species affinity for caves

International Journal of Speleology, 2018
The activity of enzymes associated with digestion can reflect food availability and feeding preferences of invertebrates in a particular habitat. Caves are mostly nutrient-poor habitats lacking primary production.

At the Edge of Survival: Exploring the Frontiers of Tardigrade Extreme Stress Tolerance

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT Tardigrades possess extraordinary resilience to extreme environmental conditions, including near‐complete desiccation, severe levels of radiation, the vacuum of space and extreme sub‐zero temperatures. Despite significant interest in their survival strategies, the molecular mechanisms underlying their survival during extreme stresses have ...

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

Severe Restriction of Glucose Import Enhances Recombinant Protein Production in Escherichia coli

Biotechnology Journal, Volume 21, Issue 6, June 2026.
Graphical Abstract and Lay Summary Producing recombinant proteins in Escherichia coli is often limited by the bacterium's tendency to consume glucose too rapidly. This excessive glucose uptake causes overflow metabolism, leading to the accumulation of acetate, a byproduct that can reduce cellular performance and protein production.

Histochemical localization of trehalase activity in dorsal flight muscle of the flesh fly Sarcophaga bullata with light and electron microscopy.

, 1975
Trehalase activity in flight muscle of the flesh fly Sacrophaga bullata is detected histochemically at light- and electron-microscopic levels by using diaminobenzidine, glucose oxidase and peroxidase in the incubation medium.
