Anaerobic Mineralization of Stable-Isotope-Labeled 2-Methylnaphthalene [PDF]
Applied and Environmental Microbiology, 2001 ABSTRACT An active sulfate-reducing consortium that degrades 2-methylnaphthalene (2-MNAP) at rates of up to 25 μM day −1 was established. Degradation was inhibited in the presence of molybdate and ceased in the absence of sulfate. As much as 87% of 2-[ 14 C]MNAP was mineralized to

Synthesis and Characterization of Stable Isotope Labeled 3,3',4,4'-Tetrachlorobiphenyl-D6
Journal of IsotopesA new synthetic method of the stable isotope labeled 3,3',4,4'-tetrachlorobiphenyl-D6 was investigated. The synthesis of 3,3',4,4'-tetrachlorobiphenyl-D6 is based on 1,2-dichlorobenzene-D4 as the labeling precursor through three steps of catalyzed ...

Stable oxygen and carbon isotope compositional fields for skeletal and diagenetic components in New Zealand Cenozoic nontropical carbonate sediments and limestones: A synthesis and review [PDF]
, 1996 The stable oxygen isotope composition (δ18O) of a precipitated carbonate depends mainly on the isotope composition, salinity, and temperature of the host fluid, whereas the stable carbon isotope composition (δ13C) reflects the source of CO2 for ...

Stable isotope labeling strategy based on coding theory [PDF]
Journal of Biomolecular NMR, 2015 We describe a strategy for stable isotope-aided protein nuclear magnetic resonance (NMR) analysis, called stable isotope encoding. The basic idea of this strategy is that amino-acid selective labeling can be considered as "encoding and decoding" processes, in which the information of amino acid type is encoded by the stable isotope labeling ratio of ...

Escher-Trace: a web application for pathway-based visualization of stable isotope tracing data
BMC Bioinformatics, 2020 Background Stable isotope tracing has become an invaluable tool for probing the metabolism of biological systems. However, data analysis and visualization from metabolic tracing studies often involve multiple software packages and lack pathway ...

Stable isotope metabolic labeling of Neisseria meningitidis lipooligosaccharide [PDF]
Journal of Endotoxin Research, 2006 The lipooligosaccharide (LOS) of a Neisseria meningitidis acetate auxotroph was metabolically labeled with either [2- 13 C]-sodium acetate or [1,2- 13 C 2 ]-sodium acetate. In this study, we demonstrated that this

An origin identification model for labeling of shiitake (Lentinula edodes)
npj Science of Food, 2021 With the increasing globalization of the food trade across countries and continents, reliable identification of the geographical origin of products is critical. In this study, we describe the limitations of the current origin labeling system for non-soil-
