The rise of atmospheric oxygen has driven environmental change and biological evolution throughout much of Earth's history and was enabled by the evolution of oxygenic photosynthesis in the cyanobacteria. Dating this metabolic innovation using inorganic proxies from sedimentary rocks has

Biodegradabilities of several hydrocarbon biomarker groups, including isoprene, hopanes and steranes in a medium-crude oil BZ34-1 and a heavy-crude oil SZ36-1 from offshore, were determined under laboratory conditions. The results of GC-MS analysis showed that isoprene biomarkers such as pristane
Cyanobacteria are key players in the global carbon and nitrogen cycles and are thought to have been responsible for the initial rise of atmospheric oxygen during the Neoarchean. There is evidence that a class of membrane lipids known as hopanoids

Phytochemical investigation of the whole plant of Dicranostigma leptopodum (Maxim) Fedde led to the isolation of a new hopane triterpene, dicranostigmone (1), and a known compound, erythrodiol-3-O-palmitate (2). The structure of the new compound (1) was elucidated by various spectroscopic
We provide high-quality, relevant hopane reference standards to be used as biomarkers for petrochemical oil field remediation and spill analysis.
