Time-of-Flight Mass Spectrometry to Characterize Inorganic Coordination Complexes and Cyanobacteria
… has been developed to detect the presence of scytonemin, a UV-absorbing pigment. Detection of scytonemin is accomplished by a simple solvent extraction of cyanobacteria in the desiccated state with subsequent MALDI-TOFMS analysis. The method is rapid and semi-quantitative. Cyanobacteria is the …

Studies in biotic persistence and the taxonomic stability of traits over geological time
… the production of photoprotective pigment scytonemin, and Chapter 4 considers microbial iron oxidation. In these two chapters, I describe a metric called “clade fidelity” of a trait to describe its tendency to be associated with certain lineages and vertically inherited within them …

Characterizing ancient chemoclines through the use of pigment biomarkers and sedimentary stable isotope signatures
… the concentration of the photoprotective pigment scytonemin and its abundance relative to that of chlorophyll a decrease logarithmically with depth, consistent with the function of scytonemin as a UV screening pigment. As well, the increase in the concentration of chlorophyll a, b and the …
