Production of pristane and phytane in the marine environment: role of prokaryotes.
Res. Microbiol. 162(9) , 923-33, (2011) This paper reviews studies dealing with the formation of pristane and phytane in the marine environment and focuses on the role played by prokaryotes in these processes. Prokaryotes may notably: (i) contribute to the formation of pristane during invertebrate ... |

Determination of anthropogenic and biogenic compounds on atmospheric aerosol collected in urban, biomass burning and forest areas in São Paulo, Brazil
Sci. Total Environ. 408(23) , 5836-44, (2010) This study was conducted at three sites of different characteristics in São Paulo State: São Paulo (SPA), Piracicaba (PRB) and Mata Atlântica Forest (MAT). PM 10, n-alkanes, pristane and phytane, PAHs, water-soluble ions and biomass burning tracers like levog... |

Isotopic biogeochemistry of the Oxford Clay Formation (Jurassic), UK.
J. Geol. Soc. London. 151 , 139-52, (1994) A total of 165 samples was obtained from the Oxford Clay Formation at seven different sites. Nearly all were from the Peterborough Member (Lower Oxford Clay), but seven were from the Stewartby and Weymouth Members (Middle and Upper Oxford Clay respectively). ... |

Biodegradation of phytane (2,6,10,14-tetramethylhexadecane) and accumulation of related isoprenoid wax esters by Mycobacterium ratisbonense strain SD4 under nitrogen-starved conditions.
FEMS Microbiol. Lett. 272(2) , 220-8, (2007) The accumulation of storage lipids during the biodegradation of 2,6,10,14-tetramethylhexadecane (phytane) by Mycobacterium ratisbonense strain SD4 grown under nitrogen-starved conditions was investigated. Detailed chemical analysis of intracellular metabolite... |

Compound-specific isotopic analyses: a novel tool for reconstruction of ancient biogeochemical processes.
Org. Geochem. 16(4-6) , 1115-28, (1990) Patterns of isotopic fractionation in biogeochemical processes are reviewed and it is suggested that isotopic fractionations will be small when substrates are large. If so, isotopic compositions of biomarkers will reflect those of their biosynthetic precursor... |

Characterization of aliphatic hydrocarbons in deep subsurface soils near the outskirts of Beijing, China.
J. Environ. Sci. (China) 17(3) , 360-4, (2005) Thirty-nine deep subsurface soils (150-180 cm depth) near the outskirts of Beijing were investagated. The concentrations including n-alkanes from C13 to C36, pristane and phytane were in the range of 0.60 to 170.10 microg/g, with a median value of 4.26. Carbo... |

Effect of time at pasture and herbage intake on profile of volatile organic compounds of dairy cow milk.
Anim. Sci. J. 87 , 117-25, (2016) Volatile organic compounds (VOCs) in milk were investigated as quantitative markers of herbage intake (HI) at pasture. Eight Holstein cows were fed indoors with concentrate and conserved forages (grass silage, corn silage and hay) (NG), then were divided into... |

The paleoecology, habitats, and stratigraphic range of the enigmatic cretaceous brachiopod peregrinella.
PLoS ONE 9(10) , e109260, (2014) Modern and Cenozoic deep-sea hydrothermal-vent and methane-seep communities are dominated by large tubeworms, bivalves and gastropods. In contrast, many Early Cretaceous seep communities were dominated by the largest Mesozoic rhynchonellid brachiopod, the dim... |
