Geographical traceability of bacteria based on a systematic stable isotope analysis method [PDF]

Applied Microbiology and Biotechnology
The outbreak of certain bacteria can trigger severe diseases, even posing a threat to public safety, leading to significant social panic and economic losses. Thus, tracing the origin of bacteria is of great significance.

Advancing Stable Isotope Analysis for Alcoholic Beverages’ Authenticity: Novel Approaches in Fraud Detection and Traceability [PDF]

Foods
Background: Alcoholic beverages have been popular for thousands of years due to their unique flavors and cultural significance. However, the industry’s high profit margins have led to increasingly sophisticated counterfeiting practices.

Isotopic Fingerprinting: A Promising Tool for Coffee Authenticity Checks

Proceedings, 2023
Almost every physical or chemical process in nature favors certain light stable isotopes over others, and thereby leaves an isotopic “fingerprint” on the substances involved.

Intracellular carbon storage by microorganisms is an overlooked pathway of biomass growth

Nature Communications, 2023
The concept of biomass growth is central to microbial carbon (C) cycling and ecosystem nutrient turnover. Microbial biomass is usually assumed to grow by cellular replication, despite microorganisms’ capacity to increase biomass by synthesizing storage ...

Evidence of considerable C and N transfer from peas to cereals via direct root contact but not via mycorrhiza

Scientific Reports, 2021
Intercropping of legumes and cereals is an important management method for improving yield stability, especially in organic farming systems. However, knowledge is restricted on the relevance of different nutrient transfer pathways.

Freezing and chemical preservatives alter the stable isotope values of carbon and nitrogen of the Asiatic clam (Corbicula fluminea) [PDF]

, 2011
We tested the impacts of most common sample preservation methods used for aquatic sample materials on the stable isotope ratios of carbon and nitrogen in clams, a typical baseline indicator organism for many aquatic food web studies utilising stable ...

Stable Isotope Analysis of Ozark Hellbender (Cryptobranchus alleganiensis bishopi) Living and Preserved Museum Tissue Reveals a Shift in Their Generalist Diet Composition

Ecologies, 2021
Ozark hellbenders (Cryptobranchus alleganiensis bishopi) have undergone marked population declines across their entire distribution. A variety of ecological life history research has been conducted to determine the cause(s) of the declines. Historically,

Diet uniformity at an early farming community in northwest Anatolia (Turkey) : carbon and nitrogen isotope studies of bone collagen at Aktopraklik [PDF]

, 2017
Aktopraklık is a settlement site composed of three areas (A–C) in the Marmara region of northwest Anatolia, with phases of occupation that date to the Late Neolithic and Early Chalcolithic periods, mid-seventh to mid-sixth millennium bc (ca.

Synthesis and analysis of stable isotope-labelled N-acyl homoserine lactones [PDF]

, 2016
Aliphatic aldehydes were deuterated at the alpha-position via a base-catalyzed exchange reaction with D2O. These deuterated building blocks were used for the synthesis of labelled analogues of quorum sensing signal molecules belonging to the three major ...
