Comments "The number of PR molecules and amount of Bchl [Bacteriochlorophyll] a per cell have been used to evaluate the commitment of bacteria with these light-harvesting systems to phototrophy in natural microbial communities (Giovannoni et al., 2005a Cottrell et al., 2006). Although PR genes and expression have been extensively examined, few studies have estimated the number of PR molecules per cell (Table 2)." See notes beneath table
