An Overview of Pterin Analysis in Biological Samples: From Occurrence and Properties to Sample Pretreatment Combined With Hyphenated Separation Techniques

Journal of Separation Science, Volume 49, Issue 7, July 2026.
ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...

Incorporating Euglena gracilis into the habitual diet modulates immune function and reduces common cold-like symptoms: a randomized controlled trial

Nutrition Journal
Background Dietary approaches to support immune function have emphasized the importance of dietary fiber, including non-digestible polysaccharides, although intake remains below recommended levels in many populations.

Structural, Compositional, and Dielectric State Profiling in Label‐Free Single‐Cell Monitoring

Small Methods, Volume 10, Issue 13, 8 July 2026.
Label‐free single‐cell monitoring leverages distinct physical interactions to access structural, compositional, and dielectric states of cells, enabling non‐perturbative, repeatable, and information‐rich measurements across diverse biological contexts. This review organizes representative platforms by intrinsic state variables and connects measurement ...

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.

Effect of Cell Disruption and Protein Extraction on the Structural and Technological Properties of Tetradesmus obliquus Protein‐Rich Extracts

Sustainable Food Proteins, Volume 4, Issue 2, June 2026.
Despite its considerable potential as a functional food ingredient, T. obliquus faces a major limitation in protein recovery due to the rigidity of its cell wall. In the microalgae industry, protein extraction typically involves two main steps: cell disruption and protein extraction.

Chlorophyll a: b Ratio Increases Under Low-light in 'Shade-tolerant' Euglena gracilis

Tropical Agricultural Research, 2011
Shade tolerance is a key adaptive strategy displayed by heliophytic photosynthetic organisms in response to limited light. Although generalized morphological and physiological traits associated with shade tolerance exist, the interest in shade tolerance ...

The Mitochondrial Genome of Euglena gracilis [PDF]

European Journal of Biochemistry, 1975
Mitochondrial DNA from Euglena gracilis has been investigated in its chemical and physical properties. Its G + C content is equal to 25%; its buoyant density in a CsCl density gradient (1.690 g/cm3) is higher, by 5 mg/cm3, than expected for a bacterial DNA having the same base composition. The buoyant densities of denatured and renatured DNA are higher

Dynamic LHCI antenna and inter‐photosystem spillover enable flexible light harvesting in Euglena gracilis

The Plant Journal, Volume 126, Issue 5, June 2026.
Significance Statement Euglena gracilis is an early diverging photosynthetic organism with a unique mosaic photosynthetic apparatus. Biochemical and spectroscopic analysis reveals a kinetically slower photosystem I sharing excitation energy with photosystem II in the absence of strict photosystem segregation.
