Ws. Kisaalita, EFFECT OF PSEUDOMONAS-FLUORESCENS-(2-79) CULTURE AGE ON THE RELATIONSHIP BETWEEN OPTICAL-DENSITY AND BIOMASS, Biotechnology techniques, 8(10), 1994, pp. 747-750
The effect of cell-cell adhesion (clump formation) on the relationship
between optical density and dry biomass was investigated for Pseudomo
nas fluorescens (2-79). Calibration curves were generated at the begin
ning, middle and end of the arithmetic growth phase, as well as during
the decay phase. The results show that use of a single biomass-turbid
imetric equation for the entire arithmetic growth phase may yield erro
neous results.
