WebChlorate-grown cultures of the five PRB strains had CD activities ranging from 25 to 50 U/mg of cell dry weight (DW), while aerobically grown cultures of the PRB had much lower CD activities (0.5-4 U/mg DW). To our knowledge, this is the first systematic comparison of the different methods to measure CD activities, and the first comparison of ... WebOct 27, 2015 · For the algal cultures with 0.1–1.2 g L−1 cell concentration, 10-mL culture volume was sufficient to get reliable dry weight using moisture analyser. To measure large number of samples, a modified method was developed which required pre-drying of samples in hot air oven at 80 °C for 15 min prior to dry weight measurement in a moisture ... modern pool table with crystal balls
