Comments "The absorption cross-section area of PSU [photosynthetic unit] in AAP bacteria is much larger than that for PRP [proteorhodopsin-based phototrophic] bacteria, a major difference between these two light-harvesting mechanisms. The estimates for cultivated AAP bacteria range from about 30×10^-20m^2 for an Erythrobacter strain to over 70×10^-20m^2 for Roseobacter denitrificans (Table 4). All of these estimates are about 10-fold larger than that of PR [proteorhodopsin] and account for much of the difference in light energy harvested by AAP and PRP bacteria. [Researchers] used the estimate for a natural community, about 60×10^-20m^2 (Kolber et al., 2001) for the linear response calculations." See note beneath table
