Effects of hydrostatic pressure on growth and luminescence of a moderately-piezophilic luminous bacteria Photobacterium phosphoreum ANT-2200.

Autor: Séverine Martini, Badr Al Ali, Marc Garel, David Nerini, Vincent Grossi, Muriel Pacton, Laurence Casalot, Philippe Cuny, Christian Tamburini

Publikováno v: PLoS ONE, Vol 8, Iss 6, p e66580 (2013)

Bacterial bioluminescence is commonly found in the deep sea and depends on environmental conditions. Photobacterium phosphoreum ANT-2200 has been isolated from the NW Mediterranean Sea at 2200-m depth (in situ temperature of 13°C) close to the ANTAR

Palynofacies and geochemical analysis of Oligo-Miocene bituminous rocks from the Moldavidian Domain (Eastern Carpathians, Romania): Implications for petroleum exploration

Autor: Matthew Makou, Gabriel Chirilă, Muriel Pacton, Daniel Ţabără

Publikováno v: Review of Palaeobotany and Palynology. 216:101-122

A palynological, palynofacies and geochemical investigation conducted on Oligo-Miocene bituminous rocks of the Lower Dysodilic Shale Formation and the Upper Dysodilic Shale Formation (Eastern Carpathians) has allowed recovery of pollen and spore asse

Until now, descriptions of intracellular biomineralization of amorphous inclusions involving alkaline-earth metal (AEM) carbonates other than calcium have been confined exclusively to cyanobacteria (Couradeau et al., 2012). Here, we report the first

Role of microorganisms in oceanic anoxic events (OAEs)

Autor: Georges E. Gorin, Muriel Pacton

Publikováno v: Geology Today. 30:215-221

The accumulation of organic matter (OM) during oceanic anoxic events (OAEs) that took place in the Mesozoic may reflect different biogeochemical pathways and feedbacks related to palaeoenvironmental changes. It originates from a combination of nutrie

Going nano: A new step toward understanding the processes governing freshwater ooid formation

Autor: Redha Farah, Muriel Pacton, Daniel Ariztegui, Crisogono Vasconcelos, Claire Rollion-Bard, Matt R. Kilburn, David Wacey

Publikováno v: Geology, Vol. 40, No 6 (2012) pp. 547-550

Marine and freshwater ooids were historically thought to form by purely physicochemical processes in turbulent environments. Recently, organomineralization has been identified as a key process for the initiation of freshwater ooid cortex formation, b

Amorphous organic matter — Experimental data on formation and the role of microbes

Autor: Muriel Pacton, Crisogono Vasconcelos, Georges E. Gorin

Publikováno v: Review of Palaeobotany and Palynology. 166:253-267

The origin of microscopically-amorphous organic matter (AOM) is problematic. It has been extensively studied because it is the dominant kerogen constituent in petroleum source rocks. Although microbes are widespread in natural environments, they are

Structural Arrangement of Sedimentary Organic Matter: Nanometer-Scale Spheroids as Evidence of a Microbial Signature in Early Diagenetic Processes

Autor: Muriel Pacton, Hans-Peter Gautschi, Crisogono Vasconcelos, Jocelyn Barbarand, Georges E. Gorin

Publikováno v: Journal of Sedimentary Research. 80:919-932

Nanometer-scale spheroidal objects (20–200 nm wide) have been widely encountered in geological samples, while their origin remains unclear. First described as “nannobacteria” (Folk 1993), they are more likely associated with various bacterial d

Discriminating the Role of Photosynthetic and Heterotrophic Microbes Triggering Low-Mg Calcite Precipitation in Freshwater Biofilms (Lake Geneva, Switzerland)

Autor: Muriel Pacton, Karine Plée, Daniel Ariztegui

Publikováno v: Geomicrobiology Journal. 27:391-399

Field and laboratory experiments in freshwater Lake Geneva (Switzerland) have recently demonstrated a substantial role of biofilms triggering the formation of ooids. However, the precise function and specificity of the microbes involved in this proce

Living stromatolites have been mostly described within shallow marine and (hyper)saline lacustrine environments. Southernmost South America lacks detailed investigations of these (organo)sedimentary buildups, particularly in regions experiencing extr
