The microorganism-microorganism or microorganism-host interactions are the key strategy
to colonize and establish in a variety of different environments. These interactions involve all …

Hopanoids and sterols are members of a large group of cyclic triterpenoic compounds that
have important functions in many prokaryotic and eukaryotic organisms. They are …

Sedimentary hopanes are pentacyclic triterpenoids that serve as biomarker proxies for
bacteria and certain bacterial metabolisms, such as oxygenic photosynthesis and aerobic …

Esta revisión es acerca de los organismos fijadores de nitrógeno, viviendo libres o en

Actinobacteria are Gram positive organisms characterized by normally having a high mol%
G+ C ratio, filamentous or non-filamentous morphologies, and some members that produce …

Bacteria of the genus Frankia are mycelium-forming actinomycetes that are found as
nitrogen-fixing facultative symbionts of actinorhizal plants. Although soil-dwelling …

The actinobacteria Frankia spp. are able to induce the formation of nodules on the roots of a
large spectrum of actinorhizal plants, where they convert dinitrogen to ammonia in exchange …

Hopanoids are ubiquitous isoprenoid lipids found in modern biota, in recent sediments and
in low‐maturity sedimentary rocks. Because these lipids primarily are derived from bacteria …

Abstract The 2‐methylhopanes (2‐MeHops) are molecular fossils of 2‐
methylbacteriohopanepolyols (2‐MeBHPs) and among the oldest biomarkers on Earth …

The actinorhizal symbiosis is a mutualistic relationship between an actinobacterium from the
genus Frankia and a wide variety of dicotyledonous plants representing 8 different families …
