these parameters were quite independent of the growth rate ( the specific growth rate varied from 1.3 h-1 in broth cultures to 0.2 to 0.3 h-1 in chemostat cultures ) and of the nature of the anionic polymer in the wall ( which was teichoic acid in cultures with an excess of phosphate and teichuronic acid in phosphate-limited chemostat cultures ) .
