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

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

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

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

International audience; Bacterial non-isoprenoid alkyl glycerol ether lipids (AGEs) are widespread in the environment but little is known about their biological precursors and mode of formation as a function of varying growth condi- tions. Here, we s

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

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

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

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

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
