Flux capacities and acclimation costs in Trichodesmium from the Gulf of Mexico (2008, methodology): “The chl a content of the lysates was determined by diluting a sub-sample in 90% acetone saturated with magnesium carbonate, and measuring the absorbance at 663 nm after correcting for absorbance at 750 nm (Porra 2002).”
Contrasting photoacclimation costs in ecotypes of the marine eukaryotic picoplankter Ostreococcus (2008, methodology): “Optical densities were corrected for background with an 80% acetone blank within a spectrophotometer (UV-1700, Shimadzu) and the Chl concentrations were calculated following Porra (2002).”

Universal chlorophyll equations for estimating chlorophylls a, b, c, and d and total chlorophylls in natural assemblages of photosynthetic organisms using acetone, methanol, or ethanol solvents (2008, methodology): “…of choice for Chl assays (see Arnon 1949, Šesták 1971, Jeffrey and Humphrey 1975, Jeffrey et al. 1997, Humphrey and Jeffrey 1997, Porra et al. 1989, Porra 1991, 2002, Wright et al. 1997, Ritchie 2006) but acetone is sometimes a poor extractant of Chl from many vascular plants and some algae,…”
Retrieval of foliar information about plant pigment systems from high resolution spectroscopy (2009, background): “The wavelength positions of maximum absorption vary with the extraction solvent used, due to differences in polarity, and the loss of pigment–protein interactions (Porra, 2002).”
