Stable Isotopes as Metabolic Probes for Nutritional Studies in Neonates
Clinics in Perinatology, 1995Metabolic and nutritional studies with stable isotope tracers have proved valuable in the human newborn. This technique is acceptable ethically, because it does not expose the infant to radioactivity, and it is sensitive enough for the analysis of very small samples.

Stable isotopes as probes for the metabolism of acetanilide in man and the rat
Biological Mass Spectrometry, 1988Acetanilide with the three hydrogens of the acetyl group replaced by deuterium was administered to 9 human volunteers (50 mg p.o.) and 5 male Sprague-Dawley rats (10 mg kg-1 p.o. and 100 mg kg-1 p.o.) and urine samples collected for 8 and 48 h, respectively.

Stable isotope probing of carbon flow in the plant holobiont
Current Opinion in Biotechnology, 2016Microbial communities associated with a plant host, constituting a holobiont, affect the physiology and growth of the plant via metabolites that are mainly derived from their photosynthates. The structure and function of active microbial communities that assimilate root exudates can be tracked by using stable isotope probing (SIP) approaches.

Identification of cellulolytic bacteria in soil by stable isotope probing
Environmental Microbiology, 2006Summary Plant residues, mainly made up of cellulose, are the largest fraction of organic carbon material in terrestrial ecosystems. Soil microorganisms are mainly responsible for the transfer of this carbon to the atmosphere, but their contribution is not accurately known.

In Situ Stable Isotope Probing of Methanogenic Archaea in the Rice Rhizosphere
Science, 2005Microorganisms living in anoxic rice soils contribute 10 to 25% of global methane emissions. The most important carbon source for CH 4 production is plant-derived carbon that enters soil as root exudates and debris. Pulse labeling of rice plants with 13

Applications of DNA-Stable Isotope Probing in Bioremediation Studies
2009DNA-stable isotope probing, a method to identify active microorganisms without the prerequisite of cultivation, has been widely applied in the study of microorganisms involved in the degradation of environmental pollutants. Recent advances and technique considerations in applying DNA-SIP in bioremediation are highlighted.

Stable Isotope Probing of Microorganisms in Environmental Samples with H218O
2019We describe a protocol for investigating microbial growth in environmental samples via stable isotope probing (SIP) with H218O. Water is a universal substrate for all microorganisms and replication is required for DNA to become labeled with 18O. By measuring how much the DNA of each taxon becomes enriched with 18O when an environmental sample is ...

Stable Isotope Probing and the Human Gut
2014This chapter describes the recent developments that have started to shed some light on the fermentative capacity of the colonic microbiota and its contribution to health and disease. The combined use of stable isotope probing (SIP) with analytical, gastroenterological, nanotechnological, and phylogenetic microarray techniques is highlighted in the ...

Profiling of Active Microorganisms by Stable Isotope Probing—Metagenomics
2019Stable isotope probing (SIP) provides researchers a culture-independent method to retrieve nucleic acids from active microbial populations performing a specific metabolic activity in complex ecosystems. In recent years, the use of the SIP method in microbial ecology studies has been accelerated.

Stable Isotope Probing Techniques and Bioremediation
2014This chapter summarizes the state of the art for applications of stable isotope probing (SIP) to bio-degradation and bioremediation research. SIP is one of the many emerging tools of inquiry used by environmental microbiologists. The goals of this chapter are to catalog and analyze trends exhibited by the majority of studies published to date that are ...
