Elemental analysis for biomass determination in the presence of insoluble substrates

Modelling aerobic biodegradation of atrazine and 2,4-dichlorophenoxy acetic acid by mixed-cultures

“…Absorbance offers an accurate indirect measurement of microorganisms' concentration (Moser et al, 1996;Péquignot et al, 1998). To correlate the absorbance at 600 nm with the real biomass concentration, measured as Volatile Suspended Solids (VSS), an internal calibration was carried out.…”

Growth of Iron(III)-Reducing Bacteria on Clay Minerals as the Sole Electron Acceptor and Comparison of Growth Yields on a Variety of Oxidized Iron Forms

“…Bacterial direct counting procedures were modified for solid-containing suspensions according to the work of Proctor and Souza (33). Biomass was determined by measuring the accumulation of particulate carbon using previously described methods (27).…”

Biological treatment of wastewater polluted with an oxyfluorfen-based commercial herbicide

“…Absorbance gives a reliable indirect measurement of microorganisms' concentration (Carboneras et al, 2017;Moser et al, 1996;Péquignot et al, 1998). A correlation curve between OD600 and the real biomass concentration, measured as Volatile Suspended Solids (VSS), was developed and used to calculate the microbial concentration.…”
